I installed a Thermostat Hub W200 about 2 weeks ago, connected to a ClimateMaster water-source heat pump, continuous building provided hot and cold water. Cooling worked correctly for about 12 days.
Two days ago, a firmware update was applied to the device. Since then, cooling no longer works — the fan runs normally when I set the thermostat to Cool, but the compressor doesn’t engage and no cold air is produced. Heating still works fine. My firmware version is: 4.5.49_0002.

Hi there.did you have try to restore the device by eliminating it from aqara app and add ut back? or first try turning off the power to your house let it for 1 min off and turning it back on as the w200 being an power device you can’t turn it off without cutting the power so this way the device can self healing properly.sometimes not many times after an update is better to do an reboot as sometimes this can fix small bugs.
I have turned circuit breaker off a couple of times just to see. This did not help.
Then next steep is to contact aqara support because if all this fails the only help you can get is from aqara support.
Thanks. I did that. I thought someone might have a similar experience.
I hope aqara support will give you the solution or my be a replacement of the device.this kind of things that you experience are rare to happen but sometimes it does when comes with electronic devices.
