OPERATING YOUR HEAT PUMP
The operation of your heat pump system is controlled by the
indoor thermostat. You simply adjust the thermostat and it
maintains the indoor temperature at the level you select. Most
thermostats of heat pump systems have 3 controls: a temperature
control selector, a FAN control, and a SYSTEM or MODE control.
Refer to your thermostat owner’s manual for more information.
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
1. During heating, increasing the thermostat setting more than
2°F may cause the supplemental heaters to be turned on for
a short period of time to satisfy the thermostat. Needless use
of the supplementary heat reduces potential energy savings.
