My hunter model # 44132 thermostat keeps flashing AUX and my heating system wont turn on

SOURCE: my hunter thermostate keeps flashing a 4 and wont turn on !

hunter thermostats are not the highest quality. on the back of the thermostat there should be a not well identified reset button. You can locate and push this to attempt to fix the problem. Or purchase a new (i would suggest Robertshaw or braeburn) thermostat and install.

Just hold down the two buttons for 5 seconds and it will be reprogrammed.

Good luck.

RE CO means Auto Recovery. In my users manual it states:

Hunter's Auto Recovery feature meets the Energy Star guideline for energy efficiency by allowing the heating or cooling system to recover gradually from an energy-saving set-point temperature to a comfort set-point temperature.

Auto Recovery calculates how early to turn your system back on. so that the room temperature is already comfortable by the start of the comfort temperature program period. Auto Recovery works in both heat and cool modes.

*When the thermostat is in Auto Recovery mode, the display will alternate "RECO" with time and the program indicator will flash.

*Auto Recovery can be disabled by sliding the Recovery switch on the circuit board to disable. (this is located inside the thermostate)

*Auto Recovery can be cancelers manually if HOLD/RETURN is pressed during the recovery process.

*Auto Recovery will be canceled and change to temporary manual override mode if the set-point is adjusted during the recovery process.



Hope This Helped!!

Hi and welcome to FixYa,

Initially, I am inclined to suspect 3 possibilities:

• sticking relay contacts (if used) (a possibility, least likely);
• dusty thermal sensor/switch for the fan (likely);
• time delay. design feature, will power down the fan only after a certain period that the heater has turned off. This is to dissipate residual heat not only on the heater but on the immediate surroundings of the heater element (most likely).

make sure you have the jumper in place
if you dont have a secondary heat source red should be on r with a jumper to rh
