Hello everyone
I need help connecting my AC unit ( carrier) Furnace and Thermostat.
There are 2 black wires coming from the relay work box.
The transformer has 2 wires Green and Red.
The Thermostat has 4 wires Red, Green, Blue, and White.
The Gas valve has 3 terminals TH, TH-TR, TR
The other side of the gas valve is a honeywell switch with a black wire looks like it was connected to one side of the transf. There are 2 red wires that go back into the relay work box. There is a button on it that switches the fan from manual to auto.
can anyone help?
Thanks
