NOTE:
If you are installing this thermostat in a new installation be sure to locate
the thermostat 4 to 5 feet above the floor in accordance with applicable building
codes. Make sure to install the thermostat in a location that provides good airflow
characteristics and avoid areas behind doors, near corners, air vents, direct sunlight
or near any heat generating device. Installation in any of these areas could impact
thermostat performance.
• Electrical Rating: 24 Volt AC (18-30 Volt AC)
1 amp maximum load per terminal
2 amp total maximum load (all terminals)
• Control Range: 45˚ - 90˚ F (7˚ - 32˚ C)
• Accuracy: +/- 1˚ F (+/- .5˚ C)
• DC Power: 3.0 Volt DC (2 AA Alkaline batteries included)
• Compatibility with low voltage single stage gas, oil or electric heating or cooling
systems. This thermostat can also be used on 250mv to 750mv millivolt heating
only systems.
• Terminations: R, W/Y, G
Replacing Existing Thermostat
1.
Always turn off power to the air conditioning or heating system prior to removing existing
thermostat.
2.
Remove the cover of your old thermostat and locate the wire terminals. Do not remove
wires from terminals until step 4.
3.
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.
4.
After labeling and removing all wires from terminals, unscrew the existing thermostat
sub-base from wall. Make sure to secure wires to prevent them from slipping
back into the hole in the wall.
NOTE:
This thermostat is designed for use with a 24 Volt-AC low voltage
single-stage gas, oil or electric heating or cooling systems. 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.

WARNING
Important Safety Information
• Always turn off power to the air conditioning or heating system prior to installing,
removing, cleaning or servicing 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 systems. 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.
• 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 heating or
cooling system control board to test the thermostat installation. This could
damage the thermostat and void the warranty.
• Do not operate compressor 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.
