It is possible to use a conventional room temperature setpoint adjuster (absolute or
relative). For more detailed information, refer to the 2 subsections below.
The 4 setpoints are readjusted according to the following rules:
• Parallel readjustment of Comfort and Precomfort setpoint
• When the Economy setpoint is reached, it is shifted along with the Precomfort setpoint
• With the Protection setpoint, the Comfort, Precomfort and Economy setpoints are
limited
The effective setpoint is displayed on the service level and on the Info page.
