Question about Coleman Heating & Cooling

1 Answer

We changed our thermostat to a digital and did not list the wiring diagram before removing the old thermostat. Now the fan will not go off unless we flip the switch on the heating unit inside. It is a Coleman Evcon, from 1994.

How do i wire analog thermostat to digital

You need to get a different can change an analog thermostat to digital, but you have to replace the motherboard with a digital compliant one. You can't just change the thermostat. Your best bet is to put back the old thermostat or upgrade to a different compatable thermostat

I have 4 wires at thermostat, g, b, w, y. The old thermostat was removed before I owned the house. I would like a wiring diagram so I can trace the wires an know how to hook up. Thx. Ken

Trace the thermostat wires into your furnace and write down which color wire ties on to which letter at the furnace terminal strip. The HVAC color code is - g (Green) = house fan b (Blue) = auxiliary w (White) = heat y (Yellow) = cooling. If you need anything, let me know. And please vote on this response. Thank you.

A/C will not shut off

Hi, the photo is showing a split system, indoor unit and outdoor unit. Is it just the blower fan inside that keeps running, or the entire a/c keeps going? Lets say its everything. I would start at the thermostat and remove the cover to expose the control wires. Find the R terminal,Red wire and use a small screw driver to remove it from the terminal. If the unit shuts off, the thermostat contacts are faulty and you will need to replace the stat. Even though its only low voltage, 24 volts, I would shut off power when you take the wire off. If your stat is not a digital, you will need to remove cover and lossen several screws to remove the stat to get to the subbase and wires. On a digital you don't have to. After removing wire, turn on power to see what happens. If it keeps going, you have a thermostat wiring problem either at the indoor unit where the thermostat wires come in and connect or at the outdoor unit where they connect touching together somewhere. The red and green or red and yellow conductor wires have a bare spot and are calling for cooling all the time. You will have to look for this, it can be very difficult to find unless you can ohm out the wires. If its only the indoor fan running and not the outdoor unit, it still could be the stat, or you have a fan relay that is stuck. If you remove the panel on the indoor unit and look at the wiring diagram, don't let it confuse you, look for this, IDF and follow the wire or wire to FR fan relay. Depending on what type, you can try tapping on it with the but of the screw driver carfully, to see if that may shut it off. If not you will need to go to a a/c parts house or a appliance parts house to find one. Draw a good diagram so you know how to hook the wires back up, or you can get into more of a bind. Its worth doing this then trying to remember. Do these things and keep me posted on this. By removing the R, red wire at the stat will kill power to the fan if the stat is the problem, so you don't have to remove the G, green wire for fan, only the red. I will wait to hear back from you.
Best of luck,

How do i change an old style honeywell room stat

Shut the furnace off for starters. Remove the old Thermostat. As you remove each wire write down what terminal it wen to.

Red wire usually goes to R-Power
Green Wire usually goes to G-Fan
White usually goes to W-Heat
Blue or Yellow usually goes to Y-Cool

Forgot to mark wires before removing old thermostat...

You can take a look at the blower unit where the wires from the thermostat connect to. Usually they're labeled on the circut diagram on the front panel, or on the board itself.

This site may also be of some assistance.

I had an old thermostat that i had to change need wiring diagram

both thermostatats will have terminal designators R,W,Y,G, possibly O/B, C, W1,W2, Y1, Y2, etc.
Simplest method is to remove wires from old stat one at a time. mark where they came from and then install at same desinated terminal on the new t-stat. Hope this helps. be sure to shut off power supply to the unit (furnace) first. The wire coming to the R (RH,RC) terminal is the 24 volt a/c hot, all others are feeding back to perform given function.

Im changing an old honeywell thermostat with a new honeywell thermostat. the old on has wires 4 wires connected to 4 screws C,R,G,W but the new thermostat has a place where the wires go which are...

Yes, I believe that you will be fine. If the original wiring is correct then I have listed the basic wiring below. As always read the directions and make sure the wiring matches your system.

Red wire = Rh (24v power, should have an exsisting jumper to RC)
White wire = W (heat mode)
Yellow (or sometimes blue) wire = Y (A/C)
Green wire = G (Indoor Fan)

How to wire hunter 44155

Go to the hunter web site. They will have the proper wiring diagrams on the site. If you cannot do that pick up a basic wiring book at your local electric parts supplier. the place you got the thermostat would be a good start. I do know that menards has some books in the electric area that would be a great help to you. You also will need to be sure that the thermostat is able to handle both air and heat. many only do heat. If this does not help let me know and I will try and get more information to you

Hunter 44630 thermostat

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)
