If the display on the thermostat is blank, verify that the air handler breaker is not
tripped, and that the indoor air handler is being powered. Also verify that the outdoor
compressor breaker is not tripped. For a gas furnace, check for power to the outlet that
provides 120v to the indoor fan at the heater closet. If the outlet is powered and the
thermostat display is still blank, call Customer Service toll free at 1-888-232-5949.

If air conditioner just shut off, or had a power interruption, wait 5 or 6 minutes until
the compressor safety "time-out" delay is passed.
•
In COOL mode, set the cool setpoint temperature to at least 4 degrees lower than the
current room temperature. Wait 5 or 6 minutes to get past the 5-minute minimum
safety delay period. If STG 1 icon is displayed and cool does not come On, schedule a
cooling and heating contractor service call. If STG 1 icon is not displayed, call
