Corrective Action
Diagnostic: Press SYSTEM button to select HEAT
and press to raise the temperature setpoint
above room temperature. Within a few seconds
the thermostat should make a soft click sound.
This sound usually indicates the thermostat is
operating properly. If the thermostat does not
click, try the reset operation described on page
17. If the thermostat does not click after being
reset, contact your installing contractor for a
replacement. If the thermostat clicks, contact the
furnace manufacturer or your HVAC contractor to
verify the heating is operating correctly.
Corrective Action
Press SYSTEM button to select COOL and press
to lower the temperature setpoint below room
temperature.
Verify thermostat and system wires are securely
attached.
Verify the outdoor unit disconnect or breaker has
not been tripped.
