Connection option 4:
Ventilation unit + Room air control +
CO / VOC / RFS sensor. Refer also to the
2
wiring diagram in the appendix.
A Ventilation unit RB 300 or RB 400
A2 Control circuit board: Jumper 8 bridged
= factory setting. Jumper 10
bridged  sensor is recognised.
B Room air control RB-D1-ZF4
B1 Room air control RB-ZF4
(option to RB-D1-ZF4)
CO2 CO -Sensor SKD, see accessories
2
VOC Air quality controller EAQ 10/2
RFS Humidity control
W1 230 VAC connecting cable
W2 Screened control cable (to be supplied
by customer) for RB-D1-ZF4 control
W2´ Control cable for room air control RB-
ZF4 (to be supplied by the customer)
W4 Connecting cable for an external CO
or VOC sensor (to be supplied by the
customer). External diameter 3,2 to
6,5 mm, z. B. LIYY 3 x 0,5 mm².
Connection to control circuit board A2
at terminals "CO2" and "OT". Set
jumper 10 (CO2) to release the
feature, see figure.
Connection of a CO
controller for the demand-driven supply of
fresh air. The ventilation unit only reacts to
sensor if ventilation level 2 (nominal
ventilation) is selected at the room air control.
VOC/RFS
Permitted connection
● 1x CO
1x humidity control RFS.
● RB-D1-ZF4 (B) not combinable with a
RB-ZF4 (B1).
● Connection of a CO
only permitted with a room air control.
● Damage of device: Never combine an
RFS with a CO
