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

removing, cleaning or ser vicing thermostat.

• Read this manual thoroughly prior to installing, programming or operating this

thermostat.

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

oil or electric heating or cooling system. This thermostat can also be used on

250mv to 750mv millivolt heating only systems.

• Do not use this thermostat on applications with voltages higher than 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.

• The system must have 24 Volt AC power present for proper system operation and

control.

• 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 hea ting 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 possibly damage the controlled cooling system and may 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.

PROGRAMMING cont. 5.4 Setting Your Energy Saving Programs cont.. 5.4.2 Using Quick Program Groups or Individual Day Programming cont.. Weekend – allows you to program the weekend days (SA, SU will show in the display) at the same time. Again, individual day programming can be used to change specific setpoint times or temperatures. Individual Days – allows you to program each day of the week individually to give you the greatest schedule flexibility.

ADDITIONAL OPERATION FEATURES cont. 6.4 High Temperature Safety Switch 6.7 Changing Fahrenheit (°F) to Celsius (°C) cont. While the thermostat is in the HEAT mode of operation (selector switch in the HEAT position), the thermostat will mechanically turn-off if the room temperature raises higher than 99˚F (37˚ C). There is also a software feature that will automatically turn-off the thermostat in HEAT mode if the temperature raises higher than 93˚ F (34˚ C). 4.

TROUBLESHOOTING SYMPTOM Thermostat does not turn on heating or cooling system. POTENTIAL SOLUTION Check to see if OFF is shown in display. 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. Compressor protection features may be in effect due to compressor short cycle conditions, power outages or rolling blackouts.

7 TROUBLESHOOTING cont. SYMPTOM POTENTIAL SOLUTION Thermostat will not allow me to program a setpoint temperature higher than 90˚ F (32˚ C). 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). Fan continues to run all the time whether the system is on or off.
