Improper installation, adjustment, alteration, ser-vice or maintenance can cause injury or property damage.HOW YOUR SYSTEM WORKSCOOLING CYCLEIf your hand is wet and you blow on it, it feels cool because some of themoisture is evaporating and becoming a vapor. This process requiresheat. The heat is being taken from your hand, so your hand feels cool.That's what happens with an air conditioner. During the cooling cycle,your system will remove heat and humidity from your home and willtransfer this heat to the outdoor air.HEATING CYCLE (HEAT PUMPS)During the heating cycle, your system will remove heat and humidityfrom the outdoor air and will transfer this heat to your home. This is pos-sible because even 0°F outdoor air contains a great deal of heat.Remember that your heat pump doesn't generate much heat, it merelytransfers it from one place to another.System OperationYour thermostat puts full control of the comfort level in your home atyour fingertips. DO NOT switch your thermostat rapidly ON and OFF orbetween HEAT to COOL. This could damage your equipment. Alwaysallow at least 5 minutes between changes.SETTING THE THERMOSTAT[ CAUTIONJThe main power to the system must be kept ON at all times to pre-vent damage to the outdoor unit compressor. If necessary, the ther-mostat control switch should be used to turn the system OFF.Should the main power be disconnected or interrupted for 8 hoursor longer, DO NOT attempt to start the system for 8 hours after thepower has been restored to the outdoor unit. If heat is needed dur-ing this 8 hour period, use emergency heat.THERMOSTATSYOUR KEY TO COMFORTAlthough thermostats may vary widely in appearance, they are alldesigned to perform the same basic function: to control the operation ofyour air conditioning or heat pump system. Regardless of size or shape,each thermostat will feature a temperature indicator; a dial, arm, orpush button for selection of the desired temperature; a fan switch tochoose the indoor fan operation; and a comfort switch for you to selectthe system mode of operation.Only approved thermostats have been tested and are fully compatiblewith this equipment. Please be aware that many different thermostatsoperate on batteries or "power stealing" principals. These types of ther-mostats can not be supported as trouble free when used with this product.If your system has been designed to allow both cooling and heatingoperation, you may have either a manual change-over type, or a pro-grammable electronic type thermostat.Manual change-over simply means that the comfort switch must bemanually positioned every time you wish to switch from the cooling toheating or heating to cooling modes of operation.A complete operating instruction is provided by the manufacturer foreach thermostat. Familiarize yourself with its proper operation to obtainthe maximum comfort with minimum energy consumption.The computerized electronic thermostat is actually a sophisticated elec-tronic version of a manual change-over type. This thermostat includesfeatures which allow "set-back" temperature variations for periods ofsleep, or while you are away during the day, and means energy savingsfor you. The thermostat also features a digital clock.COOLING ONLYIf your air conditioning system is designed to provide cooling only (AC),with no capability for heating operation (heat pump), a two-stage cool-ing only thermostat, with a manual, one-position "Cool" and "Off" com-fort switch is all that is required for system operation.COOLING AND HEATING (HEAT PUMP)If your system has been designed to allow both cooling and heatingoperation, you may have either a manual change-over type, or a pro-grammable electronic type thermostat with 2-stages of cooling and 2-stages of heat.MANUALCHANGE-OVERManual change-over simply means that the comfort switch must bemanually positioned every time you wish to switch from the cooling toheating or heating to cooling modes of operation.Johnson Controls Unitary Products 813196-UUM-C-0412
