Emergency Heat

The Emergency Heat feature allows you to Òturn onÓ the electric heat section of the system by moving the system switch to the Em. Ht. position. The LED lights and the thermostat displays ÒEm. Ht.Ó when the system calls for emergency heating. The thermostat may also display ÒAux. Ht.Ó 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.
