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 → Sensor settings. If the RLS 1 WR single control unit is deactivated on the control unit (parameter single control unit inactive), up to 4 sensors can be connected. The power supply to sensors 3 and 4 can be ensured via terminals LD1, LD2, LD3 (all 12 V DC) or with double assignment, via the 24 V DC supply of sensor connections.
