Some thermostats run on their own batteries, but some need power from the furnace to display, check this first. "P" may mean power.

Flashing Light = 1
Fault = Indoor temperature sensor open or closedcircuit.
Display = Indoor.
Indoor Operation = ON

Error code = C2 or CH2
Flashing Light = 2
Fault = Outdoor temperature sensor open orclosed circuit.
Display = Indoor Outdoor.
Indoor Operation = ON

Carrier HVAC thermostat not fully displaying digital read out. Control bottoms doesn't work have to depress really hard and eventually works

Does it have a battery backup in the unit? If so replace them. If its an older model used frequently oil from your hands gets behind the buttons which causes intermittent connections and can cause display error. Remove the unit, carefully open it up and clean all contact surfaces with q-tip and a bit of rubbing alcohol. May solve your problem. While your at it make sure all wire connections are tight. Mark all wire locations during disassembly to make sure they go back in the right place.

Perhaps you could get some help from Carrier Support here:

I noticed they have an option of talking to an engineer, and perhaps they could explain how to reset or set the unit.
Hope this helps.

No power to white rogers thermostat

Hi,
Either you blew the fuse on the air handler control board or you burnt out the air handler transformer.
The thing that blew the fuse is probably the contactor in the condenser unit. You will need to check out out cause of the outage before replacing the fuse or transformer.

the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly

Carrier Infinity Control Thermostat SYSTXCCUID01-B

Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you
