Hello again, be sure you have power to the furnace turned off when you change the thermostat, or you could blow a fuse on the printed circuit board.

Phone calls are a premium service $25 I will submit if you like or we can continue here.

Tell me what color wires were attached to which terminal letter on the old thermostat....I can coach you more effectively that way
