Emergency Heat
The Emergency Heat feature allows you to “turn on”
the electric heat section of the system by moving the
system switch to the Em. Ht. position. The LED lights
and the thermostat displays “Em. Ht.” when the
system calls for emergency heating. The thermostat
may also display “Aux. Ht.” if the system calls for
additional back-up heating (see figure to right).
When the heat pump requires servicing, the LED
lights and the system automatically activates emer-
gency heat. After contacting your service technician,
clear the LED signal by moving the system switch to
Em. Ht. then back to Heat or Auto. Auxiliary Heat
The auxiliary heaters assist the heat pump under
normal conditions when low outdoor temperature
occurs. The auxiliary heaters may also operate while
in the recovery mode to maintain comfort level. The
thermostat displays “Aux. Ht. ” (see figure above)
when the auxiliary heating equipment operates.
