The system has two different power supplies. It’s switching the power supply A to B or vice versa Automatically and instantly in case of any power failure without any interruption to the Chiller running 👍

Glad you like it 😉

Thanks!

@@rhvac I really appreciate your help! I will definitely carry out the pressure test. After that, could you advise on the best charging method? Should I go with auto charge or manual?I understand that I need to charge the system before the test operation to avoid getting the "JA" error again, so I'd appreciate your guidance on the next steps once the vacuum is completed.Looking forward to your advice!

Hi, Unfortunately by accident I deleted my previous comment in regards to how to do it 😖 But hopefully as you read it, you remember to put the system in recovery mode before doing the pressure test or vacuuming or charging it 😉 For charging the system, I usually look at the system refrigerant charge records and then I put the unit in recovery mode and charge it manually through the liquid and discharge line. After that, I personally keep it in the off position by turning the power supply isolator off for at least 10 minutes and then turn on the system and it should automatically come out of the recovery mode and power up in the normal mode 👍

@rhvac will do ,thank you for the advise

Welcome 👍

Welcome 👍

Plz describe this sign and how to clear if this light is on

Which sign!?

@rhvac do u have a whtasapp group i ll share with u

@@rhvac i have sent

Try one of these: 4618 or 4633 or 4643 or 4648 👍

The system was put in the Recovery Mode and then switched off from the main rotary isolator to be kept in the Recovery Mode so that all the Solenoid valves, Expansion Valves are kept open. You must do this if you want to Pressure test, vacuum or charge the system. To charge use the liquid service port and because of the system being in the Recovery mode the refrigerant will be running into all system. The Recovery Mode process is different for each system but this is how I put that Fujitsu VRF system in the Recovery mode: ruclips.net/video/JmrkmffPKX4/видео.htmlfeature=shared

Welcome 😊

@@rhvac if you have any other tips please share thank you

Sure 👍

Thanks 👍

Recovered the remaining refrigerant from the system and found a leak on the outdoor unit by pressure testing the system with Nitrogen. Repaired the leak and recharged the system 👍

Depending on the model, the Airedale Crac units usually have a DX condenser outside where the Compressor is located or some of them have the main components such as compressor, indoor and inside the Crac unit. You can connect the Manifold Gauge to the High and Low Pressure service ports of the compressor and use a Magnet to lift the Liquid Line solenoid valve open and recover the system refrigerant, vacuum , pressure test or charge the system 👍

How do I change the machine password and restore the old password?

You will need a high level user access password for that. Download the controller manual and you should be able to do that 👍

The TH6 is a sensor reading the Room temperature and in case of the Filter Reset, it will display an indicator when the period of cleaning filter is reached otherwise no need to turn it off.

For checking the EEV opening status that is in Palses, you need a Service Checker as the controller unfortunately doesn’t display it.

👍

Thanks 😊 In cases of your question, do you mean resetting the VRV after an Alarm!? Or do you mean the Controller password!?

@@rhvac resetting the VRV after an alarm

It depends what Error is, some Critical Error will stop and prevent the system from running until you fix the problem and then they will Auto Reset but some like Filter reset could be done via the Controller, I had posted a filter reset here: ruclips.net/video/H2vU2HS_ae8/видео.htmlfeature=shared Or here: ruclips.net/user/shorts4xEmlZmpMaE?feature=shared I will try to post more stuff about the VRVs 👍

Sure I will 😊

Unfortunately I don’t speak 🇫🇷 but I suggest that you try to use some software that does French subtitles perhaps 🤔 Good luck 🤞

It means you have a Master Controller that overrides the local controller. I assume that perhaps you have a VRF system with multiple indoor units with their controller and one Master Controller that restricts access level for the local controllers.

Glad was helpful 👍

Can u upload the photo for this table

I am going to update the link for the photo 👍

Setting No 14 will tell you how many Branch Selectors are connected (BS Boxes). VRV outdoor units are piped into the BS Boxes and BS Boxes are branched connected to the indoor units. Check this: images.app.goo.gl/4u4p5vuf28M336Qq7

As far as I know, you pair Madoka to the phone App by Bluetooth

The sounds in the background is when other DX Units Compressors loading and unloading. There are 4 DX units connected to each AHUs 👍

You can lock or unlock the options via the Madoka Assistant app on your phone 👍
