!
IMPORTANT: This feature can only be activated when used with the XCI Outdoor
Wireless Temperature Transmitter and Receiver. Please install the XCI Wireless
Temperature Transmitter and Receiver before activating this feature.
Increasing energy efficiency and reducing costs can be achieved by using the
dual fuel switch. Your heat pump can generally provide heat and comfort without
assistance to an outside temperature of just a few degrees below freezing. This
temperature is called the heat pump balance point. When the outside temperature
is above the balance point, the heat pump alone is sufficient for heating.
Once the outdoor temperature drops to the balance point the heat pump must
be assisted by your alternate energy source. When the outdoor temperature
drops below the systems normal crossover temperature (-12°C or -15°C), your
heat pump will stop operating and the alternate energy source will take over.
