Two zone setup query and ‘calling for heat’ issue
Dual zone, upstairs and downstairs - Honeywell CM707 controllers changed to wired smart thermostats
Water controller changed out to an extension unit
all TRVs changed to Smart TRVs
I have the well documented issue that only when the Smart Thermostat calls for heat will a room warm up based upon that rooms settings and this works as expected, however, if TADO change the setup so a TRV can call for heat will it work, surely a signal is required to open the zone control valve?
any others with similar experience?
