Connecting sensor

The Trio CO2 I sensor can be connected to connection W8 or W9. Configuration/parameterisation is carried out with the commissioning software, as described in the WS 120 Trio installation, commissioning and maintenance instructions.

Configuration/parameterisation of the sensor can also be undertaken with the optional RLS T2 WS control unit.

If the RLS 1 WR control unit is deactivated (Single control unit parameter inactive), connection W10 or W11 (sensor 3 or 4) can be used. The power supply to sensor 3 or 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.

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 must be activated with the commissioning software and the sensor type specified.

  1. Connect the sensor on the main board according to the wiring diagram.
  1. Slide the electronics slide-in module into the two guide rails of the ventilation unit and screw it in place with the retaining bolt.
  1. Fit front cover and hand-tighten the 6 screws. Ensure that the front cover is positioned correctly and no infiltration air can be drawn in.

Tighten the screws carefully and make sure that the front cover is not pushed in, in the area of the screw head. When using a cordless screwdriver, reduce the torque accordingly.
