Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
Our Honeywell rth230B is not turning the furnace on in that zone of the house. The other thermostats in other heat zones are fine but this one will not bring the hot water baseboard heating to that room. We were mighty cold sleeping last night. The display seems ok.
What we tried:
Resetting the filter button.
Using manual mode and the desired temp.
Switching from heat to off to cool and back.
Prior to the no heat problem, radiator in that room had been "gurlgly". We went away for four days and turned the heat OFF then. When we returned, we could not get the heat back on. The pipes could not have frozen b/c it was not below 32 while we were away.
Help us please--
It is not your thermostat, it is an airbound zone. The gurgly noise you heard was that water and air flowing through the radiator. The zone needs to be purged either at the boiler, or through vents on the radiator. Hope this helps
