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.
