21 = X12 is Jumper terminating resistance (120 W)
ModBus (remove if terminating resistance has
already been placed in ModBus system). With Mod
bus application remove the jumpers X121 & X122;
when using external Bus place the jumpers X12, X121
& X122; remove Jumper X07 from Plus pcb when a
Plus pcb is applied.
* The control cables of the fans can be switched with no problem; when
the power is switched on the appliance determines itself which is the
supply and exhaust fan! When the appliance detects another fan
(for example when a fan is replaced during service activities), then a
“wizard” starts up automatically; follow the instructions on the display
for the correct connection of the fan cables.

11 Electrical connections accessories
11.1 Connecting position switch
A multiple switch must be connected to the modular connector type X14. This modular connector X14 is
accessible from the rear of the control. With an appliance with Plus pcb the cover fi rst has to be removed
in order to gain access to this modular connector . Depending on the type of multiple switch that is
connected, one can use either an RJ11 or RJ12 plug.
It is best to use a 4-way switch with fi lter indication; always install an RJ12 connector in combination with
a 6-core modular cable.
When using a 3-way switch without fi lter indication always install an RJ11 connector in combination with a
4-core modular cable.
