Remote Thermostat Control
When connected to a remote thermostat, the indoor air temperature sensing is shifted from the unit to the remote thermostat. For this reason, the units will operate slightly differently when connected to a remote thermostat. The following chart shows the unit operation when connected to a remote thermostat.

Temperature Boost option should not be used with remote thermostat operation since this will cause the unit to switch to resistance heat when outdoor temperatures are below 46°F.
