Cooling Demand

The thermostat must be in cool mode in order to properly control the cooling equipment. When in cool mode, if the room temperature is higher than the temperature setpoint, a cooling demand is detected by the thermostat.

The thermostat will then activate the cooling equipment to satisfy the demand. Cooling operation is indicated by a snowflake icon in the SYSTEM box as shown in figure 7. When the actual temperature drops below the temperature setpoint, the snowflake icon will disappear. This indicates that the cooling demand has been satisfied and that the cooling equipment has been turned off.

Fan Control

The FAN button is located behind the small door on the right-hand side of the thermostat. See figure 3. The FAN button can be used to select either continuous fan mode or auto fan mode.

If continuous fan mode is enabled, the fan will run continu- ously regardless of whether the heating or cooling equip- ment is running. Also, ON will be displayed in the FAN box as shown in figure 9.
