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
H1 - Display element, e.g. glow lamp (to be supplied by the customer)
W1 - 230 V AC connection cable
W2, W2´ - Control cable for room air control
W3 - Cable for an external operating display (to be supplied by the customer). The connection on A2 control circuit
board is done at the “Operating display” terminals.
An operating display (lamp, contactor, etc.) can be connected to the control circuit board for external monitoring of the
ventilation unit by a building supervisor, for example. For this purpose, there is potential-free relay contact on the con-
trol circuit board “k1”.
Relay contact “k1” is closed when the ventilation unit is running. Maximum load-bearing capacity for relay contact k1 =
3A / 250 V AC, 2A / 30 V DC.
