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.
A1
Electrical terminal box RB 600
A2
Control circuit board: Jumper 8 bridged
= factory setting
B
Room air control RB-D1-ZF4
B1
Room air control RB-ZF4
(option to RB-D1-ZF4)
H1
Display element, e.g. glow lamp
(to be supplied by the customer)
W1
230 VAC connecting cable
W2
Screened control cable (to be supplied
by the customer) for RB-D1-ZF4
room air control
W2´
Control cable for room air control RB-
ZF4 (to be supplied by the customer)
80
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.
The ventilation unit is factory-set for
i
the connection of the room air control
RB-ZF4. Jumper 8 is set on the
control circuit board A2.
Relay contact "k1" is closed when
i
the ventilation unit is running.
Maximum load for relay contact
"k1" = 3 A / 250 VAC, 2 A / 30 VDC
