immediately.

•  AUTO: Heating or cooling will come on according to the heating and cooling setpoints. The

Special Heat Pump Mode: Emergency Heat

•  EHEAT: An additional system mode, “EHEAT” 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 EHEAT 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.
