Operating The New Thermostat

1) Set the System switch to either the HEAT or COOL position and the Fan switch to either the AUTO or ON

position. NOTE: In AUTO, the system blower will run only when the A/C or heat is running. In ON, the

system blower will operate continuously.

2) Use the red and blue arrow keys to select the desired temperature set point.

3) The LCD (liquid crystal display) displays the room temperature on

the left and the set point temperature on the right. Note: The set

point temperature may sometimes differ slightly from the room

temperature due to a rapidly changing room temperature or a dif-

ferential setting of 1 or 2.

Understanding Additional Features

• High Temperature Protection: While in the HEAT position, if the room temperature reaches 93 F (34 C),

the thermostat will automatically shut off. In the unlikely event the room temperature reaches 99 F (37 c),

a mechanical bimetal switch will shut off the thermostat.

• Low Temperature Protection: While in the HEAT position, if the room temperature drops below 40 F (4

C), the thermostat will automatically initiate a call for heat.

• Compressor Protection: To protect the system compressor(s) from damage, the thermostat features a 5

minute delay. After the cooling system (or heat pump turns off), the thermostat will not allow it to re-start

until the 5 minute delay expires. A blinking snowflake indicates this feature has been activated. Once the

5 minute delay expires, the snowflake will illuminate continuously and the system will be able to re-start

when called upon.

NOTE: For the purpose of unit installation, this delay can be overridden by

depressing the RESET button. This will erase any programmed settings.

• System Reset: The thermostat can be reset to factory software settings. All user entered settings will be

lost. The reset will also override the 5 minute compressor protection feature. To reset the thermostat, gen-

tly press the reset button on the front panel using a paper clip or similar small pointed object.
