CAUTION
Equipment Damage Hazard.
Can cause permanent damage to compressor or other equipment.
Do not operate cooling when outside temperature is below 50°F (10°C).
Allow compressor to remain off for five minutes before restarting.
See equipment manufacturer instructions.
❑ Slide the system switch to Cool and the Fan switch to Auto.
❑ Turn the dial counterclockwise to lower the temperature setting several degrees below the room temperature.
NOTE: If a call for cooling is made before the compressor has been off for five minutes, or if a power interruption
occurs while the compressor is running, the thermostat will go into a five-minute delay to protect the com-
pressor. The snowflake will flash during this delay.
❑ After five minutes, the thermostat will display a solid snowflake to indicate the thermostat has called for cooling.
The cooling system should turn on.
❑ Turn the dial clockwise to raise the temperature setting above the room temperature.
❑ The snowflake will disappear from the display to indicate the thermostat has ended the call for cooling. The
cooling system should turn off.
