SECTION I: SAFETY

This product must be installed and serviced by a qualified installer or service agency. Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage.

SECTION II: THERMOSTATS

YOUR KEY TO COMFORT

Though thermostats may vary widely in appearance they are all designed to perform the same basic function, to control the operation of your air conditioning system. Regardless of size or shape, each thermo- stat will feature a temperature indicator; a dial, arm, or push button for selection of the desired temperature; a fan switch to choose the indoor fan operation; and a comfort switch for you to select the system mode of operation.

COOLING ONLY

If your air conditioning system is designed to provide cooling only (AC), with no capability for heating operation (electric heat), a single-stage cooling only thermostat, with a manual, one-position “Cool” and “Off” comfort switch is all that is required for system operation.

NOTE: If you have an independent heating system (with a separate thermostat), always be sure the heating control is turned “Off” before turning on the cooling system.

COOLING AND HEATING

If your system has been designed to allow both cooling and heating operation, you may have either a manual change-over type, or a pro- grammable electronic type thermostat.

MANUAL CHANGE-OVER

Manual change-over simply means that the comfort switch must be manually positioned every time you wish to switch from the cooling to heating or heating to cooling modes of operation.
