X12 is Jumper terminang resistance (120 W) ModBus (remove if
terminang resistance has already been placed in ModBus system).
With Modbus applicaon 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.
X17 = LAN

* 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 acvies), then a “wizard” starts up
automacally; follow the instrucons on the display for the correct
connecon of the fan cables.
