Re: Offset Temperature

Try to play with offset.
In my case, this did not help and I switched (after playing with thermostat replacement) to use of room thermostat HmIP-WTH, no issues since that viewtopic.php?f=49&t=46514&start=10#top

Re: Who controls whom: temperature sensor + radiator thermostat with ccu3

Only that Virtual Device should then be used to switch settings, profiles etc. That is correct only for settings that is valid for all HMIP heating devices, right? To original question: you really need to manipulate only with HMIP-WTH-2. If that is what you meant as "temperature and humidity sensor...

Re: Floor heating + Radiators

Gas boiler has contact 230V for heating on/off. Mixer will be just on/off. I assume I must use HmIP-WHS2 to do that? While all described sounds reasonable, could you provide more details on exact purpose of those contacts group, as it described by manufacturer? This should also help to clarify conc...

Damn, pretty old bug! I think i'll stick with the 2 degree lower setpoint. Buying a WTH-2 to control a single radiator doesn't make sense.
I got to the same conclusion... :wink:

Re: HmIP-eTRV-B actuator constantly overshooting given setpoint

Hey guys, i'm having some very strange problems with my eTRV-B's. Got them a month and a half ago from cyberport (HmIP-SK9) an it seems that they are constantly overshooting the set point by 2-2.5 degrees when the boiler turns on. .... If i pair the eTRV-B with a WTH-2 it's tracking just fine. I ha...
