17 = Heater eBus (option)
18 = Plus pcb UWA2-E (option)
19 = Connection on ModBus system (option)
20 = X12 is Jumper terminating resistance (120 W) ModBus (remove
if terminating resistance has already been placed in ModBus
system).
With Modbus application remove the jumpers X121 & X122;
when using Bus place the jumpers X12, X121 & X122; remove
Jumper X07 from Plus pcb UWA2-E 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.
