INSTALLATION

2.1

Replacing Existing Thermostat

Always turn off power to the air conditioning or heating system prior to removing

existing thermostat.

Remove the cover of your old thermostat and locate the wire terminals. Do not

remove wires from terminals yet.

Using small pieces of masking tape, label wires prior to removal from terminals. Use

the chart below to determine the new terminal designations for your new thermostat.

WIRING DIAGRAMS

• Always turn off power to the air conditioning or heating system prior to installing,

removing, cleaning or servicing thermostat.

• Read manual thoroughly prior to installing, programming or operating thermostat.

• This thermostat is designed for use with a 24 Volt-AC low voltage single stage

gas, oil or electric heating or cooling systems, including single stage heat

pumps. This thermostat can also be used on 250mv to 750mv millivolt heating

only systems.

• Do not use this thermostat on applications with voltages above 30 Volts AC.

• This thermostat requires two (2) properly installed "AA" alkaline batteries to

provide power for the thermostat to properly control the system operation.

• Wiring must conform to all building codes and ordinances as required by local and

national code authorities having jurisdiction.

• Do not short (or jumper) across terminals on the gas valve or at the heating or

cooling system control board to test the thermostat installation. This could

damage the thermostat and void the warranty.

• Do not select COOL mode of operation if the outside temperature is below 50˚ F

(10˚ C). This could damage the controlled cooling system and cause personal injury.

• This thermostat should only be used as described in this manual. Any other use is

not recommended and will void the warranty.

ADDITIONAL OPERATION FEATURES Entering Your Program cont. 5.1 Review Set Temperature 8. Place the system switch in the COOL mode of operation. The display will show COOL. Follow steps 2 through 6 to program the setpoint times and temperatures for the Quick Program Group or Individual Day selection for the COOL mode. 1. Press and hold or button. The current setpoint temperature will be displayed in the place of the current room temperature, and the indicator SET TEMP will be displayed.

This indicates that the system is turned off at the thermostat. Move the system selector switch to the HEAT or COOL position. After the compressor short cycle protection 5-minute period expires the system should start within a minutes time. Low battery indicator is shown in thermostat display.

This is above the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C). Thermostat will not allow me to program a setpoint temperature lower than 45˚ F (7˚ C). This is below the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C). Thermostat will not allow me to change the setpoint. The Keypad is locked.
