Operating instructions
2
Speed selector switch
The signal lamp indicates the current operating status of the equipment:
3
Operating mode selector switch
*If the speed selector switch is in the "Auto" position, the "Day" mode of operation is active..
4
Temperature setting, day mode
For setting the required room temperature during the "day mode" phase.
5
Night mode, temperature lowering setting
For setting the required temperature reduction during the night mode
phase.
6
Timing switch
For setting the times at which the day/night mode is switched over. For a
description of this, see timing switch operation (Chapter 4.1 ff)
Releasing the motor malfunction (thermal contact triggered)
A malfunction can be released via the zero reference position of the speed
selector switch. If the malfunction has not been eliminated, the
malfunction signal will reappear (see page 9).

Fig. 4: Setting the differential gap
Differential gap of the room temperature controller
If necessary, the differential gap (hysteresis) of the temperature controller
can be changed:
We recommend a setting of approx. +/- 1 Kelvin.
