5.5.3 Connecting the eBus connector

For connecting an eBus connector, the 2-pole detachable (green) connector X17 is located at the rear of the
display cap (®). The eBus protocol may for instance be used to connect the Air Control (®
Control page 42). Because of polarity sensitivity, always connect contacts correctly; the appliance will not work if
these contacts have been interchanged! The optional CO
Electrical diagram page 35) can also be connected onto the eBus connector.

5.5.4 24 volt connection

On the X16 & X18 connector of the basic pcb, 24 volt is available.
Connector X-16 is for 24 volt connection of the optional Plus pcb.
For position connection (black) connector X16 & X18 (®
reduction at plug X16 and X18 is 5 VA per connection.

5.5.5 Connecting humidity sensor

The optional humidity sensor has to be connected onto the the X07 connection of the basic pcb. For this, use the
cable supplied with the humidity sensor. In order to connect the humidity sensor, the plastic cover above the
control has to be taken off, after which the X07 connection is accessible.
For connecting the humidity sensor, see ®

5.5.6 Connection external Bus

The Modbus/ external bus (red) connector X15 can for example be used for coupling appliances (®
appliances using external Bus
The function of this connector can be adjusted using step number 14.1 to 14.4 in the settings menu.
If the appliance is fitted with a Plus pcb, then this red connector X15 is also in use for connecting the Plus pcb;
several cables then have to be connected onto this connector X15.

5.5.7 Connecting "signal output" connector

The blue 2-pole screw connector X19. This connection is used to give a filter message or fault message.
If a filter or fault message is given in the appliance a contact is closed at connection X19. The operation of this is
set by following step number 16.1.

5.5.8 ModBus Connection

The appliance can be connected with a ModBus system such as a building management system.Using the (red)
3-pole connector X15 (or with the Plus version the red connector X06 on the UWA2-E pcb) a connection can be
made between the appliance and the ModBus system; (®
For the correct setting of the jumpers X12, X121 & X122 see the explanation given with electrical diagram (®
Electrical diagram page 35); for more information and the correct modBus settings see the separate Modbus
manual on the website!
Note: When ModBus is active, the ventilation mode cannot be changed using the display or, if applicable, the connected
multiple switch! Also any connected humidity sensor will not function.
