• Multi-Stage

*

Heat Pump

• Single Stage

• Multi-Stage

All compatible components are connected and configured by the Energy Wise Rewards technician during installation.

:

• Single Stage Gas or Oil

• Multi-Stage Gas or Oil

• Single Stage Electric

• Multi-Stage Electric

temperature differences may enable the auxillary heating mode and potentially cause your electric bill to increase
significantly in the fall and winter months.
