OPERATING YOUR UNIT

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 desired temperature 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 demand. Needless use of the supplementary heat reduces potential energy savings.

2. Ice or frost tends to form on the coil during winter heating operation. Your unit is designed to automatically melt the ice. When in this defrost cycle, it is normal for steam or

fog to rise from the outdoor unit, and for water to drain from the outside of unit. Do not be alarmed!

To star t t h e unit:

1. Turn on the electrical power supply to unit.

2. Set MODE control to desired mode and select temperature.

To shut off unit:

NOTE: If the unit is being shut down because of a malfunction,

call your dealer as soon as possible.

1. Set system MODE control to OFF.

2. Turn off the electrical power supply to unit.

Cooling Mode

With the SYSTEM or MODE control set to COOL, your unit will run in cooling mode until the indoor temperature is lowered to the level you have selected. On extremely hot days, your unit will run for longer periods at a time and have shorter “off” periods than on moderate days.

Heating Mode

With the SYSTEM or MODE control set to HEAT, your unit will run in heating mode until the room temperature is raised to the level you have selected. Of course, your unit will run for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones.

Supplemental Heat

Your unit 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 automatically turn on the supplemental heat, as needed, in order to maintain the level of comfort you have selected.

When your heat pump needs additional heat to keep you comfortable your thermostat will turn on the supplemental heat (if equipped).

Defrost Mode

When your unit is providing heat to your home or office and the outdoor temperature drops below 45F(7.2C), moisture may begin to freeze on the surface of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the
