THERMOSTATS - Your Key to Comfort

Though thermostats may vary widely in appearance, all are designed to perform the same basic function - to control the operation of your air conditioning system.

Regardless of size or shape, each thermostat 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.

The following illustrations and discussion will aid you to determine which type of thermostat you have for your system. Follow the applicable instructions in this manual to obtain the maximum comfort with a minimum of energy consumption.

COOLING ONLY

If your air conditioning system is designed to provide only cooling, with no capability for heating operation, a cooling only thermostat, with a manual, two-position “Cool” and “Off” comfort switch is all that is required for system operation.

Cooling and Heating

If your system has been designed to allow both cooling and heating operation, you may have either of two types of thermostat. A manual change-over type, or a computerized electronic thermostats.

Manual Changeover

Manual changeover 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 models of operation.

Computerized Electronic Thermostat

The computerized electronic thermostat is actually a sophisticated electronic version of a manual change-over type. This thermostat includes features which allow “setback” temperature variations for periods of sleep, or while you are away during the day, and means energy saving for you.

The thermostat also features a digital clock. If you have selected this type of thermostat, a complete operating instruction is provided by the manufacturer with the thermostat.

Fan Operation Selection

A two-position fan switch allows you to choose the type of operation of the indoor fan.

AUTO

With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cooling. This position will provide the lowest operating cost, and better humidity control on cooling operation.

ON

CONTINUOUS FAN OPERATION:

With the thermostat fan switch set to “ON”, the indoor fan will not shut-off. However, the cooling and heating systems will still operate as required by room temperatures. This provides continuous air filtering and more

even temperature distribution to all conditioned spaces. The sound level within the building will also remain relatively constant.

FAN ONLY OPERATION:

On moderate days, usually during spring and fall, when neither heating nor cooling is required, you may want to run only the fan to ventilate, circulate and filter the air in your home or building.

Set the comfort control switch to “OFF” and the fan switch to “ON”. Be sure to return the switches to their original positions for normal operation.

START-UP

The comfort control switch is assumed to be in the “OFF” position. If the main power supply to the unit is off, turn the appropriate disconnect switch to the “ON” position.

If a warning label is attached to the disconnect switch, as shown below, and if the power supply has been off for 8 hours or longer, the disconnect switch must be turned on 8 hours before the thermostat is set to operate the compressor.

IMPORTANT

IF POWER HAS BEEN OFF FOR 8 HOURS OR LONGER, DISCONNECT SWITCH MUST BE TURNED ON 8 HOURS BEFORE THERMOSTAT IS SET TO “HEAT”, “COOL” OR “AUTO”.
