The heat strip was never hooked up, there is three wires on top of the heat strip, grey, brown, and white , the thermastat is only hooked up with green yellow and red. There are two wires not hooked up a white and blue. There is a blue that is not hooked up on the unit. this is a package unit. I know that the three wires activate a relay to turn on the strip, and the white goes to both the grey and brown relays if they are some sort of relay. So I hope you can help me. drew

I installed a new Honeywell Programable thermostat, When I turned on the AC it turned on the Heater... I followed the wiring but some of it is not making sense... G=Green, Y=Yellow, R=Red, C=Blue, W2=White, Y2=Brown... The problem is that I have an Orange and Black Wire left over, Which one do I connect to W? and do I have the wiring right... my unit is a central Heat & Air, not a heat pump.

I just replace a Honeywell T87F28733844 Thermostat with a Honeywell RTH221 Thermostat since then my the furnance will not produce any heat. I replaced the thermocouple, but still no go.

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
