Special Heat Pump Mode: Emergency Heat
An additional system mode, “Heat-E” for Emergency Heat will be displayed if the HVAC System
Type is set to Heat Pump . If there is a compressor failure with the Heat Pump system, setting
the mode to Emergency Heat will allow the supplemental Aux Heat to come on first whenever
there is a call for heating . It also disables the compressor output to prevent further damage to
the HVAC system .
CAUTION!
Emergency Heat should only be used for emergencies until the HVAC system can be
repaired . Running the system in Emergency Heat mode is commonly the most expensive mode
since only the electric heat strips are being used instead of the more efficient heat pump
compressor .
