Thread: HCM200d and HR80UK TRV heads

I am happy with the system now, yes. I eventually moved the controller as it was possibly too close to a DECT phone (about 1.5m away) and nearer to the boiler controller. It is all behaving now. To explain a bit more, I fancy what was happening was that the controller was periodically losing communication with one or more of the valves. As a result it would go into a failure mode which includes cycling the boiler every 10 minutes, presumably...

Many thanks for the update. Can I ask some more questions please: Is the unit multilingual? Are the valve motors noisy at all? Have you ever needed to update the firmware? I have also been looking at the HouseHeat/HouseTech solution which is much cheaper but I have some reservations: It is only available in German (including the labelling on the plastic covers), I can't find out who makes it and what backup I could get, not sure if you...

I went for Honeywell TRVs to ensure compatibility, but it does leave a stack of TRV bodies spare. Anyone need one?

The HCM200D is not multi-lingual and the language cannot be changed via firmware updates so you need to buy the version that supports the language you require. The radiator controllers do make some noise, it is a motor driving the valve after all. we have supplied/installed thousands of these and I only know of one customer who found the noise an issue in their bedroom. In this case the radiator controller seemed to transmit the mechanical...
