Re: Heater does not turn off
It could be, or it could be a wiring issue. Make sure that your wires are in the correct place (R or Rh and W), and that they are not touching each other. If you have the unit running, and you disconnect either of the wires, it should shut off. If it does not, then the problem is in the wiring. Hope this helps

Sounds like the variances are not set right. if I am understand you. You set the thermostat to 74 and the heater shuts off at 70? If that is correct then the variances are wrong or you have placed the T stat in a bad location where it is getting heat from a vent, wall where there is a appliance or in a very drafty location
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).
I had the same set and problem. I had a RC wire which is the power to the AC. But didn't have an RH wire which is the power for the heat. To fix this just use the jumper wire and insert it in with the RC wire and hook it up to the RH. Fixed my problem.
Here is a link that will have wiring diagram it is for a similar model hunter. Also check your dip switch on the back of the stat to ensure it is set for gas (HG) or electric heat (HE) depending on your type of unit. Good Luck. Rule of thumb for most four wire systems is RED (power to stat) Yellow (Cooling) Green (Fan) White (heat)
Auto recovery – allows heating and cooling systems
to gradually recover from an energy-saving setpoint
temperature to a comfort setpoint temperature. Auto recovery
calculates the time needed to adjust the temperature to
the next program setting. When the thermostat is in Auto
Recovery mode, the display will flash alternating messages of
RECO and the time. Auto Recovery can be disabled by sliding
the recovery switch on the back of the circuit board to the
(Auto Recovery will not operate if Permanent or Temporary holds
Press Hold/Return during the Auto Recovery process to
manually cancel the recovery.
Need more information about tstat model number what type of a/c and heater do you have..heat pump, gas furnace, electric heat. Also what wires are connected to the tstat and to what position on the tstat. I have included a link to hunter's user manual page for tstats. The wiring diagrams are there just enter your model number and click submit. Good luck Kevin
