Adjusting the temperature

The temperature is changed by adjusting the setpoint on
the thermostat to a value between 41°F to 95°F (5°C to 35°C).
Use the dial on the thermostat to adjust the temperature.
A backlight will light up when twisting the dial. It shuts off
after about 10 seconds of inactivity.
The illustration below shows how to adjust the thermostat
temperature setpoint.
Figure 6-2: Adjusting the thermostat setpoint
To adjust the thermostat temperature setpoint:
• Twist the dial clockwise for a higher temperature.
• Twist the dial counter-clockwise for a lower temperature.

Replacing batteries

Replace the batteries of the thermostat when the
LED flashes twice during a heating or cooling demand.
The thermostat will perform a self test, for about
10 seconds, when the batteries have been inserted.
The system will be blocked for input and the thermostat
LED flashes during this period.
The illustration below shows how to change batteries.
