By describing the wires from your new thermostat and your old one, it sounds like your new thermostat is not compatible with your system. If you have seven wires now, then you more than likely have a heat pump system and you have to get a thermostat that is compatible with this type of system. Then you will have the connections you need.

The usual color code for thermostats are as follows:
Red (R) = Power
White (W) = Heat
Yellow (Y) = A/C
Green (G) = Fan/Blower Motor

That is for a standard 1 heat 1 cool thermostat. The other colors that you have described are usually for a heatpump system in which you have more than four wires. Depending on the furnace model, you can sometimes see the wires that go to a circuit board that are also mark with the same color codes. If so, then you just have to make sure that the w on the board is the same color has the w on the thermostat and etc. Hope this helps.

Press reset button with a straightened paper clip. Here is manual:

The Red and White wires coming from the furnace are the only ones that call for heat. the Green wire turns on the fan continuously, the yellow is for AC. If you have another wire color, it may be a Common wire and should not be used if your t-Stat has batteries. If no batteries, it goes to the C screw.

It seems that you have the emergency heat running all the time. On some t-stats there is a switch that runs the emergency heat all the time.
The other thing that could be happening is that the out door unit is stuck in defrost so the backup heat is trying to run any time you are in heating mode.
Without checking what is energizing the heat coils with an electric meter it is impossible to tell what exactly is going on.
I can tell you that I'm sure that it is related to the emergency heat, though and if you can shut off the breaker that runs that for now it will help you out till you can get it looked at futher.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Did you try calling Hunter Tech support. I had same issue and the thermostat I had was not compatable with the system I had. They immediately recommended the proper model per the number of wires that were on the old thermostat. The 800# for Tech support should be on the package that the thermostat came in.

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!!

Take it back to the supplier. If the replacement does the same it's probably a wiring fault.

Hunter Fan... | Answered on Dec 06, 2009

I hate to tell you this but that thermostat will not work with your system.
The system you have is a 2 stage system and the thermostat you got will only do one stage.
You will need to get a thermostat theat is compatible with stage heating and cooling.
The W1 is the first stage heating, the W2 is second heating. The same is true for Y1 and Y2 on cooling
You could double them up, but it would defeat the encomoy reasons for having a 2 stage unit.
Wish I could give you better news..

I hope that this will help you to solve your problem!

I am not sure the hunter is the correct type of thermostat for the heating/AC system you have. what follows is the type of systems this works with, if u don't know call Hunter support for further information.

Gas - Standing Pilot Electric Furnace
Gas - Electronic Ignition Electric Air Conditioning
Gas - Fired Boilers
Gas - Milivolt Systems This thermostat will NOT control multi-stage
Oil - Fired Boilers heat pumps or 110/220 V baseboard electric
Oil - Fired Furnace heating systems

here is alink to the PDF install instructions.

Hi, that is the indication for "Error" and you should first replace the (2) AA batteries in the thermostat, (even if you just replaced them recently) and then using a small paperclip, reset the thermostat, by inserting the unbent end of the paperclip into the reset hole next to the keypad.

Be advised that this will reset the thermostat to the default temperature and time cycle settings, so you'll have to reprogram the unit, once you've reset it. With your unit, you only need to set a weekday setting and one for each of the weekend days.

Here's a copy of the instructions for your use in resetting and reprogramming the thermostat, once you've replaced the batteries.


You can also contact Hunter tech support, should the above info not get your thermostat back in working order by calling them at 1-888-830-1326, from 8 AM to 5 PM Central Time.

I hope you find this Very Helpful and best regards!

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

Hunter Fan... | Answered on Oct 17, 2009

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.

Find the 5-digit model number (example 40170) on your thermostat. Go to http://www.hunterfan.com and paste the number into the search field at the top of the page. If Hunter still supports this product, you should be taken to the support page for it which has a link to the product manual PDF.
