Hi guys-
I want to use a 24v AC thermostat to control my goodman GM1090-3 furnace and blower.
The thermostat is a carrier programmable model and I would like to run a day/nite program to cut on heat costs.
I am confused where to connect the red and black thermostat wires on the furnace.
I see a control board with a terminal marked "24v hum", and also that board is powered by a 115 to 24v AC transformer. Can I just tap into the 24v side of the transformer? That sounds logical to me but I like to be sure.
thanks- this forum has been great to me so far.
