Heat Controller failure



Hi guys,

I have 7 heat controllers in HC3 at home. Three of seven are gone after few week using. I'm using only two heat schedules per day (morning and evening). Every time when heat controller is gone is: heat controller is fully open (full heating), any response on manual control, any response with control in HC3. Led ring not work, I can't do reset to factory reset (any response on holding button). Device looks like good in HC3, but nothing doing.

Any ideas? Today was third dead :(

The battery of the "dead" heat controllers might be totally depleted. Have you tried recharging them?

There is known problem with the current firmware that sometimes (!) for some reason a heat controller drains its battery completely in a very short time.

If this is indeed the problem you are having, version 4.9 of the firmware was supposed to fix this, but it was faulty and was pulled again, so it can not (yet) be downloaded.

Still, three valves after one week of use is unusual, so maybe it's another issue...

Similar problem here.

I have 3 TRVs with firmware 4.5 which work reliably, but the one with version 4.6 is going nuts occasionally, showing the same behaviour, cannot be controlled, neither manually nor via gateway.

After re-calibrating it, it works fine for about one week until it starts all over again, waking me up with about 23°C in my bedroom.

Using Hubitat Elevation as a Z/IP-Gateway.

What firmware version has yours?
