Great video. Question: I will be connecting this thermostat to a relay in my truck (12V). When the power is disconnected from the thermostat module (via relay) will the setting on the module remain at MY settings or will they default to a factory setting when relay restores the power to themastat module? Thank you.
Thanks a lot for the video. I got this for a project of mine and I'm trying to find if it's possible to program it so that the + - increments go by 1 degree instead of 0.1. Also, is there a way to program it so that it is on for a certain amount of time? Thanks again!
very helpful video! I purchased several of these about four years ago but need to reset it. your video helped me, because I could not remember how to set it up.
@@anandjoshi8554 well I guess it depends on the project. If it’s Nuclear reactor or a guided missile project, or a human cryogenic freezer then no! But for anything else yes, they work great. I have six of them and they work great.
Well done! Just a safety comment if I may. If you connect a test load as shown in the video be aware that 120 - 240 volts will be exposed on the back side of the circuit board. Use caution, or perhaps test with an LED and a 1K resistor in series with the relay contacts.

Hello, is it possible to connect a heater(polyamide, for instance) and heat something throughout a certain period of time, with a fixed temperature and then it goes off when the time limit is reached?
I have only one question that no seller can answer, but if the 12 volt DC power is lost, then you loose your settings and have to start again. I am guessing this because they list “Static Current” of less-than 35mA. I looked to see if someone ask the question and watched the entire video as well. As a retired automotive ASE Master Tech since 1978, at 62, I still like to learn, but truthfully want to use it for a fan over my transmission cooler. I enjoy your explanation & the equipment you use and describe your findings. If this was a hobby, I would not own a Fluke 87 V digital multi meter. I tell people asking wiring issues on vehicles to use dielectric grease where exposed to water/moisture but also good grounds and these “Star” washer to dig into the metal. Most forget the ground side on a vehicles chassis and using voltage drop as a diagnostic tool. Thanks again for your clear videos. I am saving this one for myself!
Hi Dean, The settings are saved when power is disconnected. Your assumption is correct on the amount of current. thank you for sharing your thoughts. stay safe.
@@robojax Thank you so very, very much! The “Static Current” they refer to must be the amount of current this device consumes when on, digital display shining, just no “On-Off” activity.

Hi, thank you for the detailed video. I have been using this module to control a greenhouse misting system to cool down if it reaches a certain temperature. It’s been working well up until I needed to disconnect the power supply and after reconnecting the temperature reading continues to rise up to 110c despite no significant increase in room temperature. It does this even without the temperature sensor connected. I have also tried resetting the unit with no change to result. I purchased a second unit and have had it connected for 3 weeks before it started doing the same thing. Have you experienced this and might you be able to offer some direction to fix? Thank you.
Very good explaining video... One question, can I run a 12v input into the power feed (Positive and negative) then a 12v power source into k0 and 12v appliance into k1?
How will i do? When i try to do setting in my new XH-W1209, in the P3 it goes upto only 14 (the range is between only 14 to -30). I am confuse as you mention it as 50 to -50.
Hi can you jump 12v to k1 and put the positive of the device needing to be powered (say a 12v water pump) to k0 and the negative of the pump to the gnd supply of the module?
Ty sir robojax... very informative.. very easy to install. Ordered another batch of this device for my incubator projects.. this is very useful for us beginners.. more power sir robojax...
You are welcome. See my videos on other better sensors ruclips.net/user/robojaxTVsearch?query=temperature Thank you for not skipping the ads and keep watching them. This will help me a lot.
Hi nice hardware , i was thinking if insted of lamp i run a pump cycaling water into a radiator ( not neccary just for the example ) to cool down viaclhle motor . and the sensor positaion inside the radiator . if the tempuraute goes high , above setpoint . the relay close and the pump circate. and i zm curios if there is option to aplly PID . so the pump motor doesnt turn off imadatlly , but slow down when the mesurment is 2% close to the setpoint . sorry for my spelling mistakes . thanks Netael
Hi, this is very simple timer. if you want to have full control, then use Arduino shown here ruclips.net/video/yJYXfaU9J34/видео.html if you don't know about Arduino, here is my course worth $200 on Udemy is available for free on RUclips here bit.ly/arduinoStepByStep

What is your opinion about connecting a reverse diode across the Relay terminals, to protect the contacts from potential Back EMF ?? I am switching a 12Volt 1.5A DC Fan, so a 1A rectifier should do the trick. Thank you for an awesome explanation. It was a life saver, since product ships with absolutely nothing in the way of instruction from Amazon.
Hi, Im just learning about this existing while taking abt a semester worth of time to do exactly what this does with arduino, so that sucks. I just want to ask, if I supply like 5V to the module, will the device work? I just want to use it for the temperature display and not the relay, so do I have to supply all 12V?

hello robojax....i am doing a DIY hot air station blower....the blower handle has a thermocouple....what circuit board is the best to control the temperature of the hot air blower? thanks.
I connected my W1209 to a 12v lead acid battery with battery and load gnd lead to the gnd terminal. Added a Jumper to +12v and K1 terminals and then load positive to K0 following a dc wiring diagram. When the temperature reached H set point, the fan came on as expected. Once temp reached low set point fan turned off. When I attempted to rerun the test, the W1209 lost power, it appears to have failed. I read that any voltage in excess of 12dcv could compromise the circuit board. I measured 12.8v at the battery. Can the board handle this voltage over nominal. If it can’t what can I do to supply 12 v without any over-voltage?
Hello,, if you need stable volage, get the MT3608 boost converter www.aliexpress.com/item/32948417810.html and adjust the output to 12V. Even with 5V-25V input, it will give 12V. Yes 12.8V or 13V might hram this module.
Would this work with a 12V dc supply having two of these modules in series? One to switch a fan on at a certain temperature, and the other to switch off when a certain temperature is reached
turning on and off about the load and not about the power supply. so you can connect both to the 12V. and then you can connect them as AND or OR configuration to do something. to first device is A and second is B see this page www.ee.surrey.ac.uk/Projects/Labview/gatesfunc/
Hi. Thanks for the video. I have noticed that the thermostat in the incubator I bought is constant at 37.7 C but this thermostat runs up and down. What settings will make it remain at 37.7?
There's no such thing as a constant temperature with something like this. You can get higher or lower amounts of up and down, but the relay is switching ON and OFF. Each time it switches it has to go above a certain point to turn off then below a certain point to turn back in again. There's very little you can do about this besides maybe making your chamber better insulated so there's less heat loss and more consistency. Even solid state devices that vary the power to the heater (not just ON/OFF like this one) will vary slightly, even if only a fraction of a degree.
@@lazyh-online4839 Thanks a lot. I totally agree now that I made a second incubator with thicker styrofoam and the fluctuation is not that much. Of course I'm still mystified because the insulation on my small plastic body factory made incubator doesn't look that great but the temperature fluctuations is almost not noticeable.😏
@@tomokoth4841 another thing to reduce fluctuations is to use a lower power heating element. It won't heat as fast but it also won't overshoot as much.
When you splice and the wire in half and . And put the fan on. the other end do you have the plug do you plug in the wall outlet and have the electric run through it as it's hooked up to the battery to.
Hi, is it necessary to use jumper cable wire connected k1 and 12v?? If so, what kind of cable is needed? Can i directly plug in cables from 12v adaptor?
for 12V yes it is okay. You can connect it as long as you know the polarity.. But for "jumper cable wire connected k1" sorry I did not understand it. What do you mean?
I have not see such thing. But you can buy very cheap boost converter where you can input 5V and it will boost it to 12v. I have video in that . Search my channel
@@robojax Thanks. I later saw that the solid state relay would work with an input trigger voltage anywhere between 3V to 30V to switch on high (resistive heater) loads, so no worries.
hii ,, Thanks for the full informative video .... I want to ask if this one could be used for 220V devices ?? as I just got it 125V as I didn't know that before getting it .... Thanks
This guy Robofax has obviously no clue. Sure you can use it on the switching side to switch 220V. I would'nt use this divice to switch anything, because after x times switching the realay will burn up. You need to desolder the relay and add the appropiate solid state relay for your purpose. T
@@Lisas4us can it be used to switching 12 v dc to ac ssr , safely ? Are this reliable enough to be used in a project ? or one should buy expensive controller?
Can I connect this to a 12 volt battery 1.4AH? I intend to connect a small fan and small buzzer on a compact surface. I know it has a 20amp relay so im not sure if this requires more power to activate the fan.
I am not sure you can find such thing. But you can jaw Arduino that can go up 1300C here is the basic ruclips.net/video/dVh77wT-4Ao/видео.html or with led display ruclips.net/video/cD5oOu4N_AE/видео.html or with lcd ruclips.net/video/BlhpktgPdKs/видео.html
hello, may be this ruclips.net/video/dVh77wT-4Ao/видео.html or search my channel Here is how to find Specific RUclips Video in a channel bit.ly/findRUclipsVideo
my friend, people could use it millions of ways. we can't mention them all. we say control temperature. I showed the minimum and maximum temperature value. you do whatever you want to do with it.
@robojax Back Lash: In P2 mode we will adjust one value, ie How far from the set point you want to turn on your relay again. (Assume you are in H mode ).
What’s the amperage of the module alone? I’m worried it would consume so much current in my 12V 20A power supply that would also power peltiers and fans.
this needs so much low current, when controlling AC load it would be negligible. for your information it is less than 100mA or 0.1A. for Relay power rating see this I mage snipboard.io/UDJMCg.jpg
I got a pb with mine. Sometime it is not switching light ON, when it should and I can hear a buzzing sound. When I touch it a bit, to inspect it, hope it works. And what is strange, the LCD is fine, I mean here temperature is shown as supposed. Any idea?? Thx
@@robojax Thx you, I ll investigate into Power side, and check about its voltage. I saw on another video a capacitor is remplaced. Capacitor can give a buzzing sound, but here only SMD Capacitor are present. What do you think ??
I bought one of these controllers great little bit of kit but there is a fault in the software when using it to cool a PC with a fan. When you set the temp you want the fan to kick in at you have to deduct the differential you have set from the temp you require i.e. if you want a fan to kick in at 30c with a 2 degree backlash (differential) you have to set it at 28c to achieve this. This way the fan kicks in at 30c and cuts out when it gets down to 28c . It works fine in the heating mode though
Ok, thank you. Any suggestion what thermostat would be good to use with a "12V" LiFePO4 battery(max 4x3.6V)? Would need a thermostat to control heating pads in freezing temperature.
Is it possible to calibrate to a car's stock temperature sensor? What are the electric specifications of the expected temperature sensor shown? I also would prefer Fahrenheit. I am glad to see the comment that it holds programming when power is off. Is it safe and calibrated if a car voltage changes 12v to 14v?
There is no calibration, but you can compensate for deviation as I have explained it. Add or subtract from the value. I have not tested it with 14V but most devices are mode to tolerate 2 to 2.5V fluctuation of input voltage.
A car sensor typically lowers resistance as temperature goes up. An oven sensor typically goes up 2 ohms per degree F, 1100 ohms at room temperature. What does this device expect for sensor properties?
It uses an ams1117 voltage regulator, this can handle a 15v voltage drop during regulation, so hypothetically it can go up to 20v and down to 8v, but if you get anywhere near those values you could easily fry your entire board.
Thank you for a clear and useful tutorial. I am using this controller in heating mode and have experienced a strange problem. When there is no load connected to the relay, the temperature sensor gives a steady reading as expected. However when I connect a 12V DC load to the relay the temperature sensor reading fluctuates up and down every half second, upto 2° up and down randomly. Is this a circuit defect or am I doing something wrong? Thanks for your help.
@@robojax - I inserted a suitable capacitor across the supply but it made no difference. I found that for some reason the load current was too high and the voltage too low and both were fluctuating. I replaced the power supply for the load with a current limited 12V 2 amp unit. This solved the problem. Thanks for your help. Cheers....
Very thanks for this great video, actually I'm looking for a compact module like this to control temperature between something around room temperature to around 300c using thermonuclear type k or whatever that can handle that temperature. I'll be grateful if you have any answer to this. Thanks again

If we disconnect the 12v power does it lose the settings we have ?
No. It will keep the settings.
@@robojax thank you!
You are welcome.
Very good explaining video... One question, can I run a 12v input into the power feed (Positive and negative) then a 12v power source into k0 and 12v appliance into k1?
Yes you can power this module with 12v and your load can be also 12v
How will i do? When i try to do setting in my new XH-W1209, in the P3 it goes upto only 14 (the range is between only 14 to -30). I am confuse as you mention it as 50 to -50.
something is wrong. my be this is either different or it has been programmed from the manufacturere incorrectly.
Thank you for this video. Made my project so much easier.
Glad it helped!
Hi can you jump 12v to k1 and put the positive of the device needing to be powered (say a 12v water pump) to k0 and the negative of the pump to the gnd supply of the module?
Yes, that's what I've done.
Ty sir robojax... very informative.. very easy to install. Ordered another batch of this device for my incubator projects.. this is very useful for us beginners.. more power sir robojax...
You are welcome. Sir.
Thank you so much for the explanation for this devise! It came with no information.
You are welcome. See my videos on other better sensors ruclips.net/user/robojaxTVsearch?query=temperature
Thank you for not skipping the ads and keep watching them. This will help me a lot.
Hi nice hardware , i was thinking if insted of lamp i run a pump cycaling water into a radiator ( not neccary just for the example ) to cool down viaclhle motor .
and the sensor positaion inside the radiator . if the tempuraute goes high , above setpoint . the relay close and the pump circate. and i zm curios if there is option to aplly PID . so the pump motor doesnt turn off imadatlly , but slow down when the mesurment is 2% close to the setpoint .
sorry for my spelling mistakes .
thanks Netael
Hi, this is very simple timer. if you want to have full control, then use Arduino shown here ruclips.net/video/yJYXfaU9J34/видео.html if you don't know about Arduino, here is my course worth $200 on Udemy is available for free on RUclips here bit.ly/arduinoStepByStep
Really clear and helpful explanation. Thank you!!
Glad you enjoyed it!
very nicely explained, btw can i alter the control range to 0-500 deg C by changing the sensor or this unit is calibrated for 10K NTC sensor only.
if you want higher temperature and custom display with proper functionality, then you build your own. I have shown it here ruclips.net/video/cD5oOu4N_AE/видео.html
What is your opinion about connecting a reverse diode across the Relay terminals, to protect the contacts from potential Back EMF ??
I am switching a 12Volt 1.5A DC Fan, so a 1A rectifier should do the trick.
Thank you for an awesome explanation.
It was a life saver, since product ships with absolutely nothing in the way of instruction from Amazon.
It has already the needed diode
@@robojax Thank you ..... I guess my extra one can't hurt :) ...
Hi, Im just learning about this existing while taking abt a semester worth of time to do exactly what this does with arduino, so that sucks. I just want to ask, if I supply like 5V to the module, will the device work? I just want to use it for the temperature display and not the relay, so do I have to supply all 12V?
It works with 12V only.
Thank you for your thorough explanation!!!

hello robojax....i am doing a DIY hot air station blower....the blower handle has a thermocouple....what circuit board is the best to control the temperature of the hot air blower? thanks.
Hello, because of heat you need k-type sensor. But that needs Arduno. See them here ruclips.net/channel/UCkcBSig_Iu4ZnAIeCeG1TVgsearch?query=k+type
What are your default setting temperature
I connected my W1209 to a 12v lead acid battery with battery and load gnd lead to the gnd terminal. Added a Jumper to +12v and K1 terminals and then load positive to K0 following a dc wiring diagram. When the temperature reached H set point, the fan came on as expected. Once temp reached low set point fan turned off. When I attempted to rerun the test, the W1209 lost power, it appears to have failed. I read that any voltage in excess of 12dcv could compromise the circuit board. I measured 12.8v at the battery. Can the board handle this voltage over nominal. If it can’t what can I do to supply 12 v without any over-voltage?
Hello,, if you need stable volage, get the MT3608 boost converter www.aliexpress.com/item/32948417810.html and adjust the output to 12V. Even with 5V-25V input, it will give 12V. Yes 12.8V or 13V might hram this module.
Would this work with a 12V dc supply having two of these modules in series? One to switch a fan on at a certain temperature, and the other to switch off when a certain temperature is reached
turning on and off about the load and not about the power supply. so you can connect both to the 12V. and then you can connect them as AND or OR configuration to do something. to first device is A and second is B see this page www.ee.surrey.ac.uk/Projects/Labview/gatesfunc/
@@robojax Do you have any suggestions for AND gates that can support 12v?
Can you extend sensor wire so if I want to put outside my room and will this change accuracy?
Test it with short and long sensors wire in the exact environment and you will know.
Hi. Thanks for the video. I have noticed that the thermostat in the incubator I bought is constant at 37.7 C but this thermostat runs up and down. What settings will make it remain at 37.7?
Hi, you are welcome. Test it with other temperatures. may be your temperature is fluctuating.
There's no such thing as a constant temperature with something like this. You can get higher or lower amounts of up and down, but the relay is switching ON and OFF. Each time it switches it has to go above a certain point to turn off then below a certain point to turn back in again. There's very little you can do about this besides maybe making your chamber better insulated so there's less heat loss and more consistency. Even solid state devices that vary the power to the heater (not just ON/OFF like this one) will vary slightly, even if only a fraction of a degree.
@@lazyh-online4839 Thanks a lot. I totally agree now that I made a second incubator with thicker styrofoam and the fluctuation is not that much. Of course I'm still mystified because the insulation on my small plastic body factory made incubator doesn't look that great but the temperature fluctuations is almost not noticeable.😏
@@tomokoth4841 another thing to reduce fluctuations is to use a lower power heating element. It won't heat as fast but it also won't overshoot as much.
@@lazyh-online4839 Like you adviced ,I made the second incubator with thicker walls and the temperature is holding well.

Can I use this gadget for regulating temperatures in poultry brooder ?
it is up to you to regulate whatever you want. sure. you can.
When you splice and the wire in half and . And put the fan on. the other end do you have the plug do you plug in the wall outlet and have the electric run through it as it's hooked up to the battery to.
yes. Exactly. So if you have AC load, connect it to wall outlet. If you have DC load, then connect it to battery.
What will happen when the power goes off ? We have regular power cut in our area will it retain the settings
yes it will retain the settings.
Hi, how can i get one....I think it's a good gargent...pliz let me know.
Hi, the links are in the description of the video under the video.
Hi, is it necessary to use jumper cable wire connected k1 and 12v?? If so, what kind of cable is needed? Can i directly plug in cables from 12v adaptor?
for 12V yes it is okay. You can connect it as long as you know the polarity.. But for "jumper cable wire connected k1" sorry I did not understand it. What do you mean?
As in, can I just use any wire for the "short wire" that is used to put ino K1 and 12V? Or must it be a specific wire?
Thanks. Very clear explanation of programming the device. Is there a similar module that works with 5V?
I have not see such thing. But you can buy very cheap boost converter where you can input 5V and it will boost it to 12v. I have video in that . Search my channel
@@robojax Thanks. I later saw that the solid state relay would work with an input trigger voltage anywhere between 3V to 30V to switch on high (resistive heater) loads, so no worries.
hii ,, Thanks for the full informative video .... I want to ask if this one could be used for 220V devices ?? as I just got it 125V as I didn't know that before getting it .... Thanks
You are welcome.
This guy Robofax has obviously no clue. Sure you can use it on the switching side to switch 220V. I would'nt use this divice to switch anything, because after x times switching the realay will burn up. You need to desolder the relay and add the appropiate solid state relay for your purpose. T
@@Lisas4us or just a properly rated mechanical relay. Agreed don't use this with 220.
@@Lisas4us can it be used to switching 12 v dc to ac ssr , safely ?
Are this reliable enough to be used in a project ? or one should buy expensive controller?
Can I connect this to a 12 volt battery 1.4AH? I intend to connect a small fan and small buzzer on a compact surface.
I know it has a 20amp relay so im not sure if this requires more power to activate the fan.
the voltage is the only important value. 12V is fine. you can connect 0.2A to 1000A will work.
@@robojax thank you! I intend to try the 20amp 😁
Can I find such a controller for high temperatures like 0-1000 degrees Celsius?
Thx
I am not sure you can find such thing. But you can jaw Arduino that can go up 1300C here is the basic ruclips.net/video/dVh77wT-4Ao/видео.html or with led display ruclips.net/video/cD5oOu4N_AE/видео.html or with lcd ruclips.net/video/BlhpktgPdKs/видео.html

One more question Sir.
Your example was for ac current, for dc current on the relay should I bridge KO to K1 or K1 to positive or does it matter.
this is just a switch which turn ON or OFF. you can DC or AC load. it doesn't need any other change.
Can I use this in seed germination . For controlling temp. 15 to 32 c. Please help
my friend, people could use it millions of ways. we can't mention them all. we say control temperature. I showed the minimum and maximum temperature value. you do whatever you want to do with it.
I have a 2A power supply I have connected to it and then connected a 10w heater to it. It's not running, is the A enough or does it need 10A to work?

@ 7:10 why you stopped explaining that back lash part.and @10:30 also
what is back lash? After 500k views you are the first asking for it.
@robojax
Back Lash:
In P2 mode we will adjust one value, ie How far from the set point you want to turn on your relay again. (Assume you are in H mode ).
Does it work with the Celcius scale?
yes all values are Celsius.
What’s the amperage of the module alone? I’m worried it would consume so much current in my 12V 20A power supply that would also power peltiers and fans.
this needs so much low current, when controlling AC load it would be negligible. for your information it is less than 100mA or 0.1A. for Relay power rating see this I mage snipboard.io/UDJMCg.jpg
Robojax thank man! I appreciate it a lot!
you are welcome.
I got a pb with mine. Sometime it is not switching light ON, when it should and I can hear a buzzing sound. When I touch it a bit, to inspect it, hope it works. And what is strange, the LCD is fine, I mean here temperature is shown as supposed. Any idea??
Thx
Buzzing sound seems to be weak power that can’t turn the relay ON.
@@robojax Thx you, I ll investigate into Power side, and check about its voltage.
I saw on another video a capacitor is remplaced. Capacitor can give a buzzing sound, but here only SMD Capacitor are present. What do you think ??
Wow, perfect instructions for this circuit, thanks!
You're welcome!
I use this relais for a cooling fan (switch on/off) in the housing from my FMD Printer. It works great.
I bought one of these controllers great little bit of kit but there is a fault in the software when using it to cool a PC with a fan. When you set the temp you want the fan to kick in at you have to deduct the differential you have set from the temp you require i.e. if you want a fan to kick in at 30c with a 2 degree backlash (differential) you have to set it at 28c to achieve this. This way the fan kicks in at 30c and cuts out when it gets down to 28c . It works fine in the heating mode though
Hello. Is this W1209 safe to use with 14.6V input voltage?
no.
Ok, thank you. Any suggestion what thermostat would be good to use with a "12V" LiFePO4 battery(max 4x3.6V)? Would need a thermostat to control heating pads in freezing temperature.
Does this have a remote.? Or is there any other model available with remote.?
I have shown everthing this has. just push buttons on it.
Hi mate... Will this work for 25 watt bulb for egg incubator? and AC 220 volt wall outlet?
sure it will. The relay can handle over 1000W.
Is it possible to calibrate to a car's stock temperature sensor? What are the electric specifications of the expected temperature sensor shown? I also would prefer Fahrenheit. I am glad to see the comment that it holds programming when power is off. Is it safe and calibrated if a car voltage changes 12v to 14v?
There is no calibration, but you can compensate for deviation as I have explained it. Add or subtract from the value. I have not tested it with 14V but most devices are mode to tolerate 2 to 2.5V fluctuation of input voltage.
A car sensor typically lowers resistance as temperature goes up. An oven sensor typically goes up 2 ohms per degree F, 1100 ohms at room temperature. What does this device expect for sensor properties?
I am sorry I have got no information in that regards. May be try to find the sensor model and then find manufacturer datasheeet.
@@RebChaim613
The spec. is at 7.38 , a 10Kohm NTC.
It uses an ams1117 voltage regulator, this can handle a 15v voltage drop during regulation, so hypothetically it can go up to 20v and down to 8v, but if you get anywhere near those values you could easily fry your entire board.
Thanks, great tutorial. does the device setting hold if power is interrupted
you are welcome. yes it does.
I bought one of these to make a chiller for my aquarium. My unit didn't come with any instructions. Your video was really helpful...
So how would i set it for an rv refrigerator by using this to replace thermistor?
this module works only if this temperature sensor is used and connected.
Sir can we use Ac fan or dc fan by changing circuit connection
it can control CD or DC no problem. It need 12V DC to operate. snag.gy/UDJMCg.jpg
Thank you for a clear and useful tutorial. I am using this controller in heating mode and have experienced a strange problem. When there is no load connected to the relay, the temperature sensor gives a steady reading as expected. However when I connect a 12V DC load to the relay the temperature sensor reading fluctuates up and down every half second, upto 2° up and down randomly. Is this a circuit defect or am I doing something wrong? Thanks for your help.
Your load is disturbing the power. Add 16V 1000uF or higher - and + and it should be fixed
@@robojax - thanks. Please clarify where the capacitor should be inserted - across the 12V and Ground, or across the relay contacts. Thank you.
Yes at power supply
@@robojax - I inserted a suitable capacitor across the supply but it made no difference. I found that for some reason the load current was too high and the voltage too low and both were fluctuating. I replaced the power supply for the load with a current limited 12V 2 amp unit. This solved the problem. Thanks for your help. Cheers....
