NOTE
—
Up to five M-WRG-S/Z-S ventilation units may be connected to the three-step rotary switch
and intensive ventilation pushbutton. No separate power supply is needed.
—
Please note the following if you intend to connect more than one M-WRG-S/Z-S ventilation
unit to the three-step rotary switch:
— The terminals 01 (0 V) of all ventilation units must be connected to one another (see
— The terminal 02 (+24 V DC) of the three-step rotary switch may only be connected to
the terminal 02 of a single ventilation unit (see Fig. 4).
—
The feedback from multiple ventilation units for intensive ventilation cannot be combined in
a single group signal.
—
The total length of the control cable must not exceed 50 m.
