Having wiring problems installing my honeywell rth221
I installed a new honeywell rth221 t-stat. All the wires from the old t-stat were then placed on the new t-stat (yellow to yellow, white to white, red to red, green to green except for a black one. I just pushed it back to the wall. I turned the unit on cool and then it seems like it is getting hotter instead of cooler??
