OK, so CD78E30C-66EA-4EBC-8F4D-42E086D606AC.jpg
here is a mystery - Perfectly working EH system suddenly starting giving comms errors on all 12 zones yesterday - photo attached. No new wireless devices, no new Bluetooth devices, no new alarms added, no changes made to WiFi. Battery out and rest of controller has no effect. Changed batteries in many HR92 without success.
Stranhge thing is that heating and hot water are still working, i.e. changing as needed!
Moved controller to different parts of house no change - Any ideas please?
