CAUTION
Low Temperature Hazard
Operating at too low of an outdoor temperature
may cause compressor damage.
Do not operate cooling if outdoor temperature is
below 50°F (10°C). Refer to manufacturer’s
recommendations.
Heating or cooling does not come on.
• Check power to the heating or cooling equipment.
For compressor protection, on initial startup, and
during power interruptions the Thermostat will go
into a 5 minute delay. During this delay, the cooling
icon, a snowflake , will flash.
