5. Operation with RLS 4-1 Room
air control
(surface- or recessed-
mounted version)
● WRG 35 devices are operated with RLS 4-1
UP or RLS 4-1 AP room air controls.
● Only WRG-35 standard devices,
not H versions, can be controlled.
● Up to 4 RLS 4-1 room air controls can
be networked in a ventilation system.
In this case, each control must have an
address (1 to 4) assigned to it during
commissioning. The addresses are
assigned through DIP switches.
● If several WRG devices are in operation, a
setting always affects all ventilation units.
Setting ventilation levels
 Press the ▲ or ▼ button as often as
necessary until the required ventilation
level is displayed at the room air control.
The ventilation unit switches up or down a
level accordingly (see also labelling on the
room air control).
