Question about Heating & Cooling
The "Aux HT" indicator went on, however the room temp will not go up.
I change the mode to "EHEAT", the fan on the outside unit stopped, "Aux HT" indicator is still on, however the room temp still not goes up. The air comes out of the vent is warm but not hot...
Any hint what's going on? Thanks a lot! The AUX HT Came on my thermostat, what is this, and should I be worried about it? Should I put it on EHeat instead for some reason? It is pretty cold outside (in the low 20's). My unit is not that old, is there a problem? Please help!!
You have a heat pump which removes heat from outside air when it is too cold out below 30* the unit can no longer produce heat and electric strip heaters kick in

The unit is probably to small for theare you are trying to heat.
When the Aux HT light came on that meant the heat pump could not keep up with the demand for heat. (Probably due to extreme cold, or undersized unit.)
If yu have heat, then at least one heat strip is operating. If you have multiple heatstrips, one or more could be malfuncioning.
Or it could simpy be to cold/to small fr your area and not able to keep up.
How many square foot are you trying to heat?
What is the outside temp?
What is the inside temp?
What size unit (BTU output) do you have?
