Hi. I have a blank display on one of my Radio Thermostat CT80 7-Day Programmable thermostat. How can I fix this? There is nothing wrong with the breaker.
Please check the connection of your C and RH wires, Pull up on the C wire and make sure it has a good connection and doesn’t pull out — do the same with the RH wire.. If it pulls out then reconnect it and see if it works. Also if the HVAC is not working please cycle the breakers.
If it still not working please let me know when you purchased it and where you purchased it from.
We look froward to hearing from you.
