Have HVAC Questions? Ask an HVAC Expert for Answers
I will be happy to assist you with this. Can you tell me what wires you had to what terminal on old thermostat?
This all looks correct There should be a function 2 set to 0 also (You heat pump reverses in COOL mode)
I will stand by if you want to try everything.Did you turn off power to air handler before you started? If not and system does not work, look for a small auto type fuse in air handler which may have blown if any wires touched and sparked.
Let me know if everything works.If not we will go from here. Keep in mind we will have a 5 minute delay between heat and cool before thermostat allows unit to come back on.
If you have further questions, please let me know.
