5 CHECK THERMOSTAT OPERATION

CONTINUED FROM THIRD PAGE

Before you begin using your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, gently pull it straight out from the base. To replace the cover, line up the cover with the base and press gently until the cover snaps onto the base.

Operating Features

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

•SIMULTANEOUS HEATING/COOLING SETPOINT STORAGE — You can enter both your heating and cooling setpoints at the same time. There is no need to re-enter the thermostat at the beginning of each season.

•TEMPERATURE SETTING — Press or until the display shows the temperature you want. The thermostat will keep the room temperature at the selected temperature.

•°F/°C CONVERTIBILITY — The factory default setting is Fahrenheit. If you need Celsius temperature setting, go to menu mode and change the fifth option to C (see configura- tion menu, page 5).

•TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However,if you wish, you may adjust your new thermostat temperature

display to match your old thermostat. This can be accom- plished (within a ±4° range) by going into the menu mode (see configuration menu, page 5).

2)Select FA or SL (Fast or Slow) Heating Cycle Rate—The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is normally for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and can be set to

your personal preference. FA cycles the system just under 1°F and the SL setting cycles at approximately 1.5F°.

3)Not Available

4)Select Compressor Lockout LOC OFF or ON—Selecting LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling cycles. This is intended to help protect the compres- sor from short cycling. Some newer compressors already
