W8 Connecting cable (provided by customer) for
external VOC sensor, e.g. LIYY 3 x 0.5 mm²
W8’ Connecting cable (provided by customer) for
external relative humidity sensor 1,
e.g. LIYY 3 x 0.5 mm²
W8‘‘ Connecting cable (provided by customer) for
external switch / potential-free contact
(function pulse ventilation /sensor type = digital),
e. g. LIYY 2 x 0,5 mm²

sensor 2, e.g. LIYY 3 x 0.5 mm²
W10 Connecting cable (provided by customer) for
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 (parameter for simple control unit
inactive), 4 more sensors can be connected.
The power supply to sensors 3 + 4 can be
ensured via terminals LD1, LD2, LD3 (all 12
VDC) or at double assignmenet via the 24
VDC supply of sensor connections 1 and 2.
