Connection option 3:
Ventilation unit + Room air control +
External operating display. Refer also
to the wiring diagram in the appendix.
An operating display (lamp, contactor, etc.)
can be connected to the control circuit board
for an external monitoring of the ventilation
unit by a building supervisor, for example. For
this purpose, there is potential-free relay
contact "k1" on the control circuit board.

A2 Control circuit board: Jumper 8 bridged
= factory setting
B Room air control RB-D1-ZF4

(option to RB-D1-ZF4)
H1 Display element, e.g. glow lamp
(to be supplied by the customer)

not combinable with a RB-ZF4-control
(B1).
W3 Connecting cable for an external
operating display (to be supplied by
the customer). External diameter
3,2...6,5 mm, e.g. LIYY 2 x 0,75 mm².
The connection on control circuit
board A2 is done on the "Betriebs-
anzeige" terminal.
Relay contact "k1" is closed when the
i
ventilation unit is running. Maximum
load for relay contact "k1" = 3 A /
250 VAC, 2 A / 30 VDC
