i bought a honeywell digital thermostat and followed the directions on wiring it up and now my fan blows all the time and the outside unit doesnt come on.. i have no power to the blend air II box.. when i switch the thermostat to heat the whole thermostat turns off.. im experienced in wiring so i need a wiring diagram to rewire from the outside unit to the inside unit to the thermostat.. thanks..

Hi,

Red to t-stat RH

Yellow to Y

White to W

Green to G

If it has the setting inside with pins to set, set for HE .

The yellow from t-stat will connect to terminal strip Y in furnace or by wire nut or molex plug.

It will connect to a wire going to outside condenser.

There will be another wire from secondary-common side of transformer and it will connect with other wire from outside condenser via terminal strip, wire nut or molex connector plug.


That is for a normal 4 wire hook-up for electric furnace and straight a/c.


Thanks,
Robert

yeah everything is right.. i also have wires commin from the deluxe blend air II box .. i have more than 4 wires going to the t-stat im guessing for the a/c unit.. my old t-stat was a mercury style and it had like x1 and x1 or y1 and y2 or somethin like that.. but either way i cant even get power to my t-stat with the blue wire on 'c' .. the only thing that i can get power to is the blower (which never cuts off)

What is the outside condenser model number ?

Is your t-stat battery operated ?


Thanks,
Robert
