With all the wires connected (including the C wire), it is time to turn the AC power back on. Do this at
the breaker you used to switch it off. The CT80 will power-up in the control OFF mode. Your CT80 is

function.
IMPORTANT: Make sure the CT80 is powered up and is in the OFF mode before set-up. (To turn
your thermostat off, press the
display and touch OFF). Heating and cooling systems must be confi gured separately.
