EMER
Requires the CT102 HVAC TYPE be set to Heat Pump.
If you set your CT102 HVAC type to Heat Pump with the HVAC setup
program selected to enable auxiliary heat, the emergency function is
available on the Manual screen. Enabling Emer On disables the heat
pump and leaves auxiliary heat as your sole heating source.
Auxiliary heat is more expensive than the heat pump so use this
feature only if the heat pump cannot keep up or is defective. This
manual override stays active until you disable emer by switching the
thermostat to another mode.
