If your thermostat does not power on, please check the
following:
1. Turn off the power to your system. Check that all wires
are properly inserted into the terminal blocks at the ther-
mostat. Tug lightly on the wires to ensure they are not
loose.
2. Ensure you turned the power back on to the equipment
either at the switch at the indoor equipment or the electri-
cal panel (where you originally turned off the equipment).
3. If your device still doesn't power on check the AC voltage
between Rc and C or Rh and C using a multi-meter to
ensure it is 24V AC.
