Settings Setting FAN and SYSTEM Switches Fan and system settings are controlled by using FAN and SYSTEM switches located on the bottom of the thermostat case. First set the FAN switch: Auto: Normal setting for most homes. In cooling, the fan goes off and on with the cooling equipment. In heating, the fan may start a few minutes after the heating equipment comes on. On: The fan runs continuously. Use for improved air circulation and air quality.
Then set the SYSTEM switch: Cool: Normal setting for months when your home needs cooling (air conditioning). Digital display shows a snowflake when cooling is on. Off: Both heating and cooling are off. Heat: Normal setting for months when your home needs heating. Digital display shows a flame when heating is on.

Troubleshooting Guide CAUTION Low Temperature Hazard Operating at too low of an outdoor temperature may cause compressor damage. Do not operate cooling if outdoor temperature is below 50°F (10°C). Refer to manufacturer’s recommendations. Heating or cooling does not come on. • Check power to the heating or cooling equipment. For compressor protection, on initial startup, and during power interruptions the Thermostat will go into a 5 minute delay.
• Check that the SYSTEM switch on the thermostat is set to Heat or Cool. • Check the system fuse or circuit breaker and replace or reset if necessary. • Check for air movement at the register. Temperature setting is too warm or cool • Adjust the temperature by pressing either the ▲ or ▼ key.
