Compressor Protection
Compressor protection is enabled/disabled in the Installer Settings (See Installer Manual). If enabled, this
feature is automatically present in cooling and/or heating modes. This thermostat includes an automatic
compressor protection delay to avoid potential damage to your system from short cycling. This feature activates
a short delay after turning off the system compressor. Additionally, for multi-stage heat pump systems, this
thermostat provides cold weather compressor protection by locking out the compressor stage(s) of heating for
a period of time after a power outage greater than 60 minutes. This cold weather compressor protection can be
manually overridden at any time by changing the system mode to OFF momentarily, then back to HEAT.
