Connection of sensors to WS 170 KBR / KBL / KBRET / KBLET
A - Ventilation unit
A1 - Electronic slide-in module
A2 - Controlled domestic ventilation unit control
CO2 - CO2-sensor (# accessories)
VOC - Air quality controller (# accessories)
r.h. - Humidity sensor (# accessories)
T-S - Intermittent ventilation button / external potential-free contact

W9 - Connecting cable (provided by customer) external CO2 sensor 2, e.g. LIYY 3 x 0.5 mm² W10 - Connecting cable
(provided by customer) external sensor 3, e.g. LIYY 3 x 0.5 mm²
W11 - Connecting cable (provided by customer) for external sensor 4, e.g. LIYY 3 x 0.5 mm²
The control’s sensor inputs can be freely parametrised.
The inputs are not defined for a particular sensor type.
When commissioning a sensor, the sensor input on the control must be activated and the sensor type specified #
Commissioning and maintenance instructions.
If the RLS 1 WR is deactivated (parameters – single control unit
inactive) on the controller, a connection of up to four sensors is possible.
The power supply to sensors 3 + 4 can be ensured via terminals LD1, LD2, LD3 (all 12 VDC) or with double assign-
ment, via the 24 VDC supply of sensor connections.
