Question about Honeywell TH4210D1005 Heater
I have a goodman heat pump with a honeywell th4210d thermostat, the auxiliary heat will not turn on when outside temperature is in the low 25-30 degree range,unless there is a setting of 5 or more degree difference between room temp and temp setting the problem is I cannot maintain a steady room temp. How does thermostat know when to turn on aux. heat? Thanks
Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

"PLACE A JUMPER (PIECE OF WIRE) BETWEEN Y AND W IF YOU ARE USING A HEAT PUMP WITHOUT AUXILIARY/BACKUP HEAT." if this dosnt work check the fuse in the air handler you may have blown it if you did not turn the unit off before installing.
