Heat Pump
*
:

Furnaces:
• Single Stage Gas or Oil
• Multi-Stage Gas or Oil

• Millivolt Heat System
Aux Heat:

All compatible components are connected and configured by the Energy Wise Rewards technician during installation.
* If you have a heat pump, make sure your heat settings are no more than 2˚ between the warmest temperature,
the one you set when you are home, and coolest temperature, the one you set when you are away. Large
temperature differences may enable the auxillary heating mode and potentially cause your electric bill to increase
significantly in the fall and winter months.
