Zones being activated when not being called for

Hi there,

Had a quick search through the forums on this, and whilst I am sure this is simple, I couldn't find it. Evohome controller with a hot water and 3 heating zones. When I call for heat on heating zone 3 (with a DT92e wireless thermostat and a BDR91 wireless relay), it turns on the hot water and one other heating zone (also a DT92e and BDR91) but interestingly the remaining heating zone, which uses the EcoHome controller as its thermostat, remains off.

I have checked the system devices screen and the Appliance Control is set to off. All the heating zones have Heating Type set to Zone Valve, and Stored Hot Water in Enabled and using a Hot Water Valve.

If this was some appliance relay thing, why is the zone using the EvoTouch sensor not firing as well? Any thoughts?

Pete

Hi Pete,

Multiple zone valves with evohome should be setup as the BDR91's operating the 'zone valve zones' and then a single BDR91 acting as a 'appliance relay' and hot water setup as 'hot water only'.

This will cure the issues.
