    ABSOLUTELY SUPERB Video!!! I could not believe I had EXACTLY the same manual Thermostat in place as this one and was changing it for the same Digital one as.here (both Honeywell). My Manual thermostat in the hall had stopped working. My good friend and I (both ladies) changed this ourselves, watching this video step by step on my IPad - lol. Procedures SO well and clearly explained. SUCCESS!! Thank you SO MUCH for this wonderful video.

    .... A few weeks ago I plumbed in and fitted a new radiator - but it would only get luke warm and not heat up properly - I was about to call in a plumber but I found your video - and it showed me how to ballance the system and it immediately sorted the problem. Now, just last week my old 30+ year Honeywell room thermostat in the hallway stopped working (so no central heating for a week) - so I followed this video and replaced it for exactly the same one in your video following your instructions. Heating now working perfectly again. This is now the second time lately that your videos have got me out of trouble - and saved me having to call in (and pay) a plumber / electrician ..... Thank you so much 👍👍👍 Keep up the good work - saved me a few bob .... small donation sent 👍👍

    Good video, I have been told the yellow wire and the restrictor has a reduced power connection to the boiler. I was warned should you connect the 240v directly to the boiler you can kill the circuit board in the boiler.

  • @benbradley2331

    Brilliant help mate. I had a old bio.metric British gas stat. Plumb shop suggested Drayton turn dial stat. Fitted it. Wouldn't even tell boiler to come in... Reason. Has relay that needs 240v in my red wire i only get 190v. Dont know why. But i went out and bought this honeywell u have. Works a treat. U saved my day. So thank you !

  • @Olivarus238

    I know that this is an old video, but it's nowhere near as old as my Honeywell thermostat. It dates back to 1991 and pre-dates the one that you replaced in the video. So I have just replaced it with DT90E, even though that must be at least 4 years old by now. Thank you for the "If you've got red, yellow, blue and earth" section, because that's exactly what I have. Using the red and yellow stopped me using the blue! It's perfect and working well. Great video!

  • @leonbryce8384
    @leonbryce8384 Год назад +4

    Great video, but as an electrician I do not advise just cutting the earth wire off, sleeve it and pop a wago on. It makes it easier for testing purposes not only that when not connected together you are unable to obtain r1 r2 readings which then can become costly on the customer as it’s not always easy to find 👍🏿

  • @happyharry7331
    @happyharry7331 3 года назад +1

    very accurate thermostat the only downside is it continues to monitor the room temperature even when the heating is off with a loud click when it senses the temperature is low, not a problem if you are in a large house and are remote from the thermostat. We are in a small bungalow and the click is loud I basically turn the thermostat to the frost setting and that stops it. and turn it on again in the morning. Checked this out on several websites and other people also moaning about the loud click

    Hello.
    Thanks very much for your informative video. My central heating failed to fire at the weekend. Water was okay but the heating wouldn't come on when I turned the thermostat up or put the heating on constant. I ordered the same Thermostat control in the video and fitted it last night using your wiring instructions for the yellow and red wires. Bingo! works fine. So Thanks.
    Can't help thinking that your very calming voice is also of great benefit to anyone watching these films as most like me will be in some state of panic at the thought of an impending night of minus seven degrees with no heating. Your somewhat soothing manor acts almost as therapy for anyone in such a situation. So much so that the next time I get stressed out I might watch one of your films just for the calming effects despite not having any central heating problem.
    Cheers

    Hi nice little video . in the old days the electricians used red/black plus earth cable to wire a stat exactly as you have . Now they have to use twin brown cable I would have put a bit of brown or red tape on the black cable just to identify it being a live cable .

    A great explanation, nice and simple, excellent! Quick question, in my current unit ( exactly the same as yours) Th current wires are as follows: EARTH x 2 wires, Number 2 slot BLUE wire, Number 3 BLACK wire, Number 1 slot BROWN wire..... Would I be right in the new unit wiring to be: LIVE, into A slot- BROWN, NUTURAL into B slot- BLACK, or BLUE?
    Any advice guidance would be greatly appreciated.!
    Again, thanks so much a great source of no nonsense example.

    Hello del, i found this ole video you done and it gave me all the confidence to install. It was very easy to do mine had the 3 wires. The neutral is actually for the resistor/ Heat Anticipator to make the stat work more accurately as you say within 2 deg rather that yours which is 5 deg. But i see the digital ones know work within 1 deg of accuracy without need for neutral . Once again big thanks to you taking the time making these videos. nice one.

I showed him your video and two minutes later it's up and running. Thanks.

    Hi, firstly thanks for this useful video. I have one of these fitted as per your instructions and it seems to work ok. However, as a couple of people have mentioned, it calls for heat when the timer/programmer is off and the room cools. Is that a 'feature' of this model? If so can I assume it's basically a battery operated on off switch governed by the temperature and not affected by the timer/programmer.

    Great video, this helped me with fitting mine within a house I've just brought, first house.
    I could do with a little bit of help if you, or anyone, can spare some. My new room thermistat is set to 18c, which is where I want it, but once it reaches this temperature the radiators don't turn off. I still have to go round an manually turn off all the radiators is the house, but the radiator valve. I thought my thermostat would take over from the valves but it hasn't. Any advise on how I could make this happen.
    Thank you in advance

    Hi, My wires are confusing me. I have Brown, Black, White (with some blue tubing on it) and the earth. Its a combi boiler and I have bought the Honeywell THR840DUK digital thermostat. I am assuming I connect Brown to (A) and Black to (B) and then tape up Blue and Earth. Is that right?

    @freebornjohn2687 3 года назад

    Great video. This setup works well with a big room and a dedicated pipe run to a valve, but how do you have thermostats in different rooms with individual radiators operating off a single run? Am I missing something? - but the ideal would be an accurate thermostat in each room commutating with the radiator valve in the same room.

    • @dereton33
      @dereton33  3 года назад

      Yes it would but you will need smart valves for each room and stats, so an expensive option.

    Hi thanks for your informative videos.
    But it’s gone wrong for me this time.
    I followed your replacement Honeywell room stat video.
    Apparently I have a High voltage system, so I’ve blown the fuse in the boiler.
    There was no mention of High/Low voltage systems in your video ?

    • @dereton33

      That video is a bit old now. So if you are unsure about the wiring do consult an electrician. This wiring I showed was for a high mains voltage system.

    My cable only has a black and a green/yellow wire. There is NO red or blue wire. I'm not sure it's even function, as the black wasn't properly connected to the live slot. It is very old wiring (before 1980). How do I wire a new digital one?
    I believe the cable is a 6241y.

    hey Al, love your videos. I have a Worcester greenstar combi boiler, I have a very old fashioned myson analogue thermostat connected to it, looks like it's been there since the 70s/80s. I have had a look to see what wires it has. it has blue wire connected at the top, red wire connected at the bottom and a bare wire connected in the middle. there is a loose yellow wire not connected to anything. so can you just confirm which wires I need to connect to this new unit? is it red in the A terminal and the yellow that is not connected to anything in the B terminal? and the blue and bare wire safely tucked away.

      dereton33 so connected the red and yellow, wouldn't fire the boiler. wasn't brave enough to try another wire, so got a qualified electrician out, better safe than sorry. after he checked the wiring, turned out it was the blue wire that was the live switch. glad someone professional did it for me. Thanks for you help Al.
