Question about Heating & Cooling
Hydronic Buderus system, Honeywell controllers (above).
Three zones, each master/slave.
One zone giving trouble.
In one zone, with thermostat set at 61 degrees, heater does not kick on, even when ambient room temperature is 51 degrees. Cycling the thermostat, i.e. "off/on", then setting temperature at 65 degrees or above, will deliver heat.
When running, heater will heat room to temperature set on thermostat (e.g. 62 degrees = 62 degrees). Problem is, thermostat won't kick heat on - even with 10 degree difference in set vs. actual temp.
