Troubleshooting Guide

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 manufacturers
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.
