W4 - Connection cable for external CO2 sensor and/or VOC sensor (provided by customer). Connection to A2 provided 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.



WS 170 ventilation unit with hygrostat and RLS 1 WR or RLS D1 WR room air control

A - WS 170 electronic slide-in module

A2 - Control circuit board: Jumper 8 bridged and jumper 10 (CO2) = open (= factory setting)

B - RLS D1 WR room air control

B1 - RLS 1 WR rH room air control HY 5 or HY 5 I hygrostat

W1 - 230 V AC connection cable

W2, W2´ - Control cable for room air control

W4 - Connection cable for external hygrostats (to be supplied by the customer). Connection to A2 control circuit board at CO2 terminals

When connecting a hygrostat with potential-free contact for demand-driven removal of moisture, the hygrostat must have a potential-free switching output.

The hygrostat always switches the ventilation unit to ventilation level 3 if the set humidity value is exceeded (potential-free contact in hygrostat closes).

If the humidity in the room drops, the ventilation unit switches back to the previously selected ventilation level.

If you switch manually from ventilation level 3 to level 2 or 1, this deactivates the automatic function of the hygrostat temporarily. This is then switched back to active if the level drops below the hygrostat set point once.

Connect the hygrostat to terminal "CO2".

Jumper 10 on the A2 control circuit board must be open.

Set the switching point at the hygrostat manually.

Never connect a hygrostat and a CO2 sensor/VOC sensor at the same time.



WS 170 ventilation unit with differential pressure controller and RLS 1 WR or RLS D1 WR room air control

A - WS 170 electronic slide-in module

A2 - Control circuit board: Jumper 8 bridged (= factory setting)

B - RLS D1 WR room air control

B1 - RLS 1 WR room air control

P - Differential pressure controller with potential-free relay contact k (provided by customer)

k - Switching output, potential-free relay contact

W5 - Connection cable for differential pressure controller (provided by customer)

If there is negative pressure in the room, the differential pressure controller switches the fans in the ventilation unit off. This blocks the room air control RLS 1 WR. The LED display goes out. The unit is only released again when the differential pressure controller switches the fans back on. The ventilation unit runs again at the same ventilation level

as before it was blocked.



WS 170 ventilation unit with NTC 15 supply air temperature sensor and RLS 1 WR or RLS D1 WR room air control

A - WS 170 electronic slide-in module

A2 - Control circuit board: Jumper 8 bridged (= factory setting)

B - RLS D1 WR room air control

B1 - RLS 1 WR room air control

GW1 - Gateway frost protection heat register

GW2 - Gateway bypass shutter (only WS 170 bypass unit)

T1 - Supply air temperature sensor in

supply air channel (provided by customer)

W1 - 230 V AC connection cable

W2, W2´ - Control cable for room air control

W6 - Connection cable of supply air temperature sensor. Connection on GW1 circuit board to KL2 terminals.

For WS 170 in passive-energy houses, an NTC 15 must also be installed to protect against icing over (if the supply air is too cold). The ventilation unit then switches off at supply air temperatures of less than 6 °C.

Only in Comfort and Bypass units when deploying a supply air temperature sensor: Remove the resistor on GW1 circuit board at the KL2 terminals.
