Question about Honeywell Programmable Thermostat Heater
This has happened to three different thermostats, so I know it's not the thermostat. We have a two-stage heat, one-stage cool heat pump that's about 11 years old. The outside unit says "Aire Flo" and the inside unit says "Intertherm". Never had to have it worked on. A/C works perfectly in the summer. When winter hits, we turn the temp up to, say, 74. Heat will kick on and when thermostat hits 74 it kicks off. About 5-10 minutes later, the fan will kick on again but it will blow cool air instead of warm. So it seems like it's running the "emergency heat" to get it up to temp, then the heat pump part kicks on and blows cool. I do not know for a fact that this is what it's actually doing. This is on the "heat" setting, not the "auto" setting where it could run heat and cool on the same day. HVAC guy said everything looks like it's running and wired properly, but something must be amiss. He was a little "green" and needless to say it's not fixed. Any suggestions?
Heat pumps defrost which is the AC mode, if the heat strip isnt working during a defrost, the air will be cold, A heat pump only feels warm if the heat strips are on too! the refrigeration cycles heat output is much less sensible to our 98F skin. heat pumps that satisfy a room setpoint are working at least, all heat pumps feel drafty to most.

SOURCE: Heater running continuously
Sounds like you have a problem with your heat pump. Your aux heat is a electric coil. how old is the unit when was the last time it was serviced? How cold is it out side?

However - the problem is probably not with your thermostat but with your furnace. It is most likely a dirty flame sensor - a maintenance issue. If you have not had your furnace serviced recently (more than 1 year) that is where you should start. Modern furnaces require regular maintenance.

Sounds like it could be a effiency function to warn you that the heat elements are on. Check your thermostat manual and see if you can turn this feature off. If this is not a feature then the thermostat may be wired wrong or something in the circuit may be trying to short out.
