Hi
Twice over the past four months I have woken to find that all the HR80UK valves in my system have lost communication with the HCM200D and hence set themselves to a very generous 20C
There were no changes made the night before (in fact none barring a slight schedule change in several days). No power cut. HCM200D not complaining of anything and still showing the various valves as installed. No changes to other wireless equipment around the house. All the batteries were replaced a few months ago...
Re-installation of each valve gets them working again and the time programs have not been lost. I haven't checked the boiler controller yet to see if it has also disconnected although I suspect it has gone too.
Anyone else experienced this and if so do you have any ideas of the cause please?
Many thanks
David
