    I’ve had 2 mass communication failures since installing in November. Both times the dt92 thermostat in the living room has shutdown/batteries went flat. Both times multiple zones were either demanding heat or losing contact.

    I would agree with this hypothesis regarding batteries and the failures spreading out. I do think Honeywell should be investigating this issue as there is no way a low battery in one device should be allowed to affect the entire system.

    We had a suspicion mine was down to the ‘phantom override’ problem but the double dt92 failure always niggled as being just too coincidental.
