5.3 Operating, Control, and Safety Switch
5.3.1 The system is operated with the rotary switch and indicator on the operating
panel.
5.3.2 The blower switch is the main switch for the air conditioner. This can also be
used to vary the speed of the vaporizer blowers and the corresponding air flow.
– level 1 50% air flow
– level 1 70% air flow
– level 1 100% air flow
5.3.3 Use the thermostat switch to switch off the coolant compressor and to regulate
the room temperature. The control operation is started by switching the coolant
compressor off and on. The switching is regulated by the air temperature and the
compressor speed.

and the entire air conditioning system. This switches the coupling off in abnormal
operating situations.
