Intertherm to Honeywell thermostat
Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.

I have an intertherm electric furnace FEH-A020, with multispeed blower installed when A/C added. My problem is blower operation. at the end of the cooling season with fan set to auto operation the fan ran continuously. Now that I've turned the unit back on for heat the blower will only function with the switch in the on position (continuous operation), in auto mode the heating elements come on with the signal from the thermostat (Honeywell CT3400), but the fan does not. I checked the fan relay p

I have a Intertherm P3rA-042K that runs the ac at the same time as the heat strips. I have a Honeywell RTH3100c I have the red wire at R the Yellow at Y the Green at G and the W2 at aux. I had a jumper between Aux and E like the manual said but it makes no difference. Also for some reason it was hooked up before with a blue wire joined with the red at the unit and the blue going to B at the thermostat. I removed the blue as i saw no use for it and it still doing the same thing. The unit froze up

Honeywell thermostat is out. Tried replacing battery but still out. Trying to replace with temporary Honeywell thermostat but can not figure out wiring. I have a white, red, and blue wire. The original thermostat is a Honeywell Vision pro IAQ.
You will need a voltmeter. I believe 2 of the wires (probably the white and red are the power; either 12 or 24 volts) and the blue is the switch leg.\015\012\015\012If you don't have a voltmeter, you can twist the blue and the white toget ... Ruud UAMB Air Conditioner
Intertherm Thermostat I bought a programable thermostat to replace the intertherm. I am confused about the wires. The intertherm has an x wire, it is black but there is no x wire option with the new thermostat which is a Hunter 44860.

Borg warner Is the old round York Borg/Warner thermostat incompatable with a Honeywell? I just replaced my old round mercy switch thermostat with a Honeywell RTHL111 thermostat. The air conditioner service man says it is hooked up right, but the fan on the unit will not run on auto (it must be in the on position on the thermostat [thus the fan runs all the time]). He also replaced a relay switch inside the unit. We are using air conditioning only on this unit. Red to R (strapped to Rc), gree

I have an American Standard Freedom-80 Two stage furnace/AC. After replacing my old Honeywell with a new Honeywell RTH2310 thermostat (which the guy from A-1 Heating & A/C assured me was compatible with my system) the A/C won't kick on. The thermostat is registering the ambient temp & when I turn the thermostat fan switch to ''on'', the fan turns on, but not with cold air. I have not even tried the heat because it was 89 degrees F inside already, but would expect the same issue. The metal doo
If your system worked prior to installing the new thermostat, then you may have to change how your thermostat is wired in the rear, as I encountered the exact same problem in that regard. Beyond that, if you have a blinking light, chances are it may ... Air Conditioners

HONEYWELL RTH230B thermostat: we just installed the honeywell rth230b. The fan is working, but it's not turning on the outside unit.

I have just purchased a honeywell ct87n, could you please provide a schematic in order to connect it properly.

Hi The old thermostat broke down and the AC technician bypassed the thermostat on our external Brivis Buffalo.

Well, how did he bypass the thermostat? Is it just a wire? First turn off the power to the unit and then simply remove the bypass by cutting it out or unscrewing it. I'm not exactly sure what he did, but if you take a picture and post it here of t ... Air Conditioners
