Having trouble the heat in one zone of the house.
Have a direct vent setup (purefire - gas - radiators ) . 3 story twin, house is one zone, back family room on another ( addition )
Using two honeywell programmable therms. One on the house is working fine.
Problem is the one in the addition is being odd.
Past few nights it has been cold. Rads are getting warm but the therm is reading 68 degrees ( inside temp ). Problem is I have it set at 70 ( on hold there ) . It wouldnt go past 68 until today I had to push the therm to 75 then then the inside temp hit 70. So i dropped the temp to 70. ( also scheduled to hold on 70 )
Went to check it again....dropped back down to 68 on the inside temp. I have no idea what is going on with this thing. The other therm is working fine.
Suggestions? Is it the system itself? Therm bad ( it is brand new )? Should I just unhook it and rehook it back up?
