Setting a New Temperature Differential
IMPORTANT: The default temperature differential is factory set at 1°F. When your room temperature
varies by 1°F, the thermostat turns your system on. If you notice your system turning on and
off too frequently, increase the temperature differential accordingly.
Step 1: Remove cover. Insert a coin or screwdriver in slot at top if needed.
Step 1: Press the reset button once (see diagram on Page 1).
Step 3: The display will show
This is the temperature differential setting.
Step 4: Press the or button to adjust the temperature differential down or up.
Step 5: Replace the thermostat cover.
The display will return to the room temperature display five
seconds after the last input. The new temperature differential
setting will be saved.
Starting the Thermostat
Step 1: Move the Fan switch into the Auto position.
• In Auto, indoor fan runs only during a heating or cooling cycle
• In ON, indoor fan runs continuously
Step 2: Move the Mode switch to either Cool or Heat position, depending on
the season. The thermostat will now operate and maintain the room
temperature at the desired setpoint.
Note: When the thermostat operates the system, there is built-in
compressor protection. After the compressor turns off, the
system will not turn it back on for about five minutes. This
protects the compressor.
