Configuration of sensor 3 / sensor 4

Conditions for connecting sensor 3 and sensor 4: Single control unit inactive parameter

Parameters: Sensor 3 / sensor 4 configuration

Set value: yes / no

Parameters: Sensor 3 / sensor 4 type

Set value: CO₂, VOC, r. h., digital. If digital, then Start/Stop, night-time cooling, flush mode, motion detector.

The function of the original single control unit connection on the RLS terminal is changed to two more sensor connections:

• 0-10 V inputs on terminal S1+ for sensor 3 and terminal S2- for sensor 4
• 12 V supply voltage on terminals LD 1 - LD3

The supply voltage of sensors 1 and 2 can be used for 24 V sensors. Yes activates the connected external sensors named/specified by type. The name appears on the main control unit. If the digital type sensor parameter is selected, the 12 V supply voltage can be looped via a pushbutton and returned to the associated 0-10 V input (S1+ or S2-) 6 Main menu settings. When the pushbutton is pressed, the ventilation unit switches to intermittent ventilation for the time stated under Duration of ventilation level. Once this time has elapsed, the ventilation unit switches back to the previously selected ventilation level.
