Configuring/activating sensor

The sensor can be parameterised with the commissioning software or on the optional RLS T2 WS control unit.

  1. Connect the PC/notebook to the ventilation unit (USB) → Front side of ventilation unit.
  2. Call up commissioning software. Select USB connection. The start screen appears.
  3. Call up the Installer parameter and enter the service code. The programme changes to the Installer level.
  4. Select the Device settings/Sensors parameter.
  1. Activate the desired sensor (1, 2, 3 or 4), set to CO2 and name it. The name appears on the main control unit.

Minimum limit values apply to reduced ventilation (RV) and maximum limit values for intensive ventilation (IV). Linear control is used between the two.

  1. Set the CO2 limit value min. and CO2 limit value max..
    Setting value for CO2 limit value min.:
    500 ... 800 ... 900 ppm (factory setting 800 ppm)
    Setting value for CO2 limit max.:
    1000...1230...2000 ppm (factory setting 1230 ppm)

Be sure to set the sensor’s CO2 control voltage for 0 V and 10 V as follows.

  1. CO2 control voltage 0 V: Setting value 0 ppm
    CO2 control voltage     10 V: Setting value 2000 ppm
  2. Remove USB cable, test settings and functions.
