Jumper settings (Chapter 6.7.3)
J 1-3 Unit type, 000 = WS 170
J 4-5 Frost protection temp. (Chap. 6.7.4)
J 6 No function
J 7 Jumper 7 open: Ventilation level 3 is
reset after an hour.
J 8 RLS 1 WR or RLS D1 WR room air
control active: Leave factory setting,
J8 must be bridged.
J 9 Jumper 9 open: The ventilation unit
can be switched off at the room air
control. Jumper 9 bridged:
RLS 1 WR: Switch-off function blocked
RLS D1 WR: Ventilation unit runs in
"Humidity protection ventilation"
ventilation level in the OFF switch
position.
J10 HY 5 or CO
sensor, jumper 10 must be open.
Jumper 10 open: Hygrostat released
with potential-free contact.
Jumper 10 bridged: CO
(0 to 10 V output) released.
Further connection options
W3 Connection cable (provided by custo-
mer) for external operating display.
k1 Potential-free relay contact (max.
3 A / 250 V AC, 2 A / 30 V DC).
The contact is closed when the
ventilation unit is running.
Connection cable (provided by cus-
W4
tomer) for external CO
sensor or external hygrostat (with
potential-free contact).
W5 Connection cable (provided by
customer) for external differential
pressure controller.
Differential pressure controller with
potential-free relay contact. Minimum
switching power of relay contact:
230 V AC/2 A. Remove J1 bridge on
A2 control circuit board.
W6 Connection cable (provided by
customer) for external differential
pressure controller.
Sensor type=NTC 10k. Remove
resistor 12k on GW1 circuit board.
