Pulled the thermostat (AC, vs, circuit, outside)

[eugenet]

Hey everyone,

I was mowing and ripped out the thermostat wire from the AC condenser unit outside. There are 3 wires, green, red and white.

These clip into a circuit board on the AC unit, one black and one yellow wire.
Anyone know whether it's red and black or red and yellow vs white and black or white and yellow?

There is 24 V running through the thermostat wire and the AC kicks in if i depress the contactor, just wanted to know the right polarity for these wires.

Thanks.

Take off the thermostat in the house and look ant the markings wherew the wire is connected. That should get you going.

Red = Thermostat power wire(24 Volt) - R connection

White = Cooling call - W connection

Green = Fan switch in T-stat - G termination.

It is as easy as it looks.

This is a cooling only unit, correct?
