The flush-mounted thermostat is adapted to the requirements of different heating systems. The optimal use of energy resources is made possible by various functions. The Optimum Start function allows the thermostat to save heating energy independently, as it "learns" how much lead time is required to reach the desired temperature at the set time, avoiding unnecessarily long and expensive preheating. If you go out of the house for a few hours, the party timer can be used to adjust the temperature to suit your needs during this time without having to intervene in the program.

To monitor energy consumption, the controller can display usage from the last few days up to the last 12 months, providing the user with the necessary information to optimize room-specific heating energy consumption. In addition to a proportional control method, the thermostat also offers two-point control. For special applications where frequent burner switching must be avoided, a restart delay can be specified.

In summer, the room temperature controller can also be used to cool the rooms or switched off completely thanks to the integrated mode changeover. The valve or pump protection function ensures that pumps and valves start up again without any problems after the summer break. In the event of a malfunction, the heating output is reduced to 30%, preventing the room from overheating or cooling down. The frost protection function prevents damage due to cold snaps and switched-off controllers, while the unauthorized person and child protection prevents unwanted adjustments.

All versions of the clock thermostat have flash memory in which all data is safely stored, even in the event of a power failure. The very large display with backlight allows easy reading of the displayed values and operation of the control element, even in unfavorable lighting conditions.
