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/1.1°C 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 sav- ings.

Step 1ÐCooling Mode
With the SYSTEM or MODE control set to COOL, your heat pump will run in cooling mode until the indoor temperature is lowered to the level you have selected. On extremely hot days, your heat pump will run for longer periods at a time and have shorter ªoffº periods than on moderate days.
Step 2ÐHeating Mode
With the SYSTEM or MODE control of your indoor thermostat set to HEAT, your heat pump will run in heating mode until room temperature is raised to the level you have selected. Of course, your heat pump will run for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones.
Step 3ÐSupplemental Heat
Your heat pump is your primary heating source. Your system may also be equipped with a supplemental heating source such as electric heat. On cold days and nights, your system will automati- cally turn on the supplemental heat in order to maintain the level of comfort you have selected.
When your heat pump needs additional heat to keep you comfort- able, your Carrier electronic thermostat will turn on the supple- mental heat (if equipped) and display the ªAUX HTº message.
