Questions and answers
How to turn system on
The Honeywell Home T4 Pro Series thermostat system turns on automatically when properly wired and powered. Ensure the thermostat is installed correctly and connected to power. If the system does not turn on, check the wiring, power source, and ensure the C-wire (common wire) is connected if required. If the system is in a delay mode, wait for the built-in compressor protection time to elapse before it starts operating.
