Test Operation
• On the thermostat, slide the Mode Switch to COOL. Press the COOLER
or WARMER button until the set temperature is 10 degrees below
room temperature. The HVAC unit should energize in the cooling mode
(Page 6). Note: You may need to wait up to five minutes for cooling to
energize due to the compressor lockout feature.
• On the thermostat, slide the Mode Switch to OFF. Slide the Fan Switch
to Fan On. The fan should turn on and run continuously (Page 6).
