5 Override button / party mode In the time switch program, this button allows you to quickly change from the active temperature level to the next and back. Thus, you can quickly change to energy saving temperature when you leave the apartment for a short period of time, thus saving energy. The display indicates the change. It is valid only until the next switching time. Activate party mode: Press the button for 3 seconds. Party mode is available only in operating modes and .

Operating modes 24-hour operation with time switch program The controller offers the two time switch programs . and Example A with 2 heating phases Enter a start time and end time for each heating phase. The comfort temperature setpoint can be freely entered and is the same for both heating phases. Between the heating phases the controller always switches to the same, freely selectable energy saving temperature setpoint.

Remote control Use a suitable remote control unit to activate the "Remote control" temperature setpoint in the controller. Changeover takes place by making a potential-free contact connected to terminals T1 and T2. A flashing symbol indicates active remote control mode. After the contact opens, the previously set operating mode is reactivated.

A Sensor calibration: DIP switch 1 If the displayed room temperature does not match the measured room temperature, the temperature sensor can be recalibrated. Set DIP switch to ON and press the DIP switch reset button: CAL symbol is displayed. The currently measured temperature flashes. Press or to recalibrate by max. ± 5 °C. Set DIP switch to OFF and press the DIP switch reset button to save the settings.
