t stat wiring problem

3408 Views 4 Replies 4 Participants Last post by  Tinman_iii
My furnace (gas) has C G Y W R
for controls.

Stat itself (digital) has Y RC RH (jumper in place on rh an rc) W G C H2 H1

what I would like to do is use the "cool" function of the thermostat to strictly start the blower. I have no "cooling" in place, I just would like to run the blower on the t-stats "cool" cycle to help circulate the air.

any input?

thanks in advance.

Most thermostat will energize both Y and G when calling for cooling, so you should not need to do anything other than verify your G thermostat wire runs to the air handler's G terminal.

Let us know if that doesn't work, and please post make and model of thermostat.
