A2 - Control circuit board: Jumper 8 bridged (= factory setting) Jumper 10 bridged = sensor is detected.
B - RLS D1 WR room air control
B1 - RLS 1 WR room air control
CO2 - SKD CO2 sensor
VOC - EAQ 10/2 air quality controller
W1 - 230 V AC connection cable
W2, W2´ - Control cable for room air control
W4 - Connection cable for external CO2 sensor and/or VOC sensor (provided by customer). Connection to A2 provid-
ed by customer at CO2 and OT terminals. Set jumper 10 (CO2) to release the feature
When connecting a CO2 or VOC sensor for the demand-driven fresh air supply. The ventilation unit only reacts to the
sensor if ventilation level 2 (nominal ventilation) is selected on the room air control.
If a CO2/VOC sensor is connected, only one RLS 1 WR room air control may be connected.
Never operate an EAQ 10/2 air quality sensor together with a CO2 sensor.
