Good morning everyone. So I have a little annoying dilemma on my hands with the fireplace and HVAC system. Problem is is that when it's cold out like last night (30 but felt like 20 degrees), I have the fireplace on and the fireplace fan is set to a setting that's quite yet continuous once the fireplace reaches a certain temp. The problem: When my fireplace is on for a while the rest of the house gets pretty cold except for the main floor that has the fireplace. It dawned on me that the furnace isn't kicking on as often because the thermostat is being satisfied by the fireplace. Is there a way around this and what are some methods to tackle this one? A second thermostat on the second floor that somehow communicates with the main floor thermostat to say "hey it's getting cold up here so u must turn on"?
