The profi-air 180 flat connection box is
an extension of electric connection
options for the profi-air 180 flat ventila-
tion unit. It is connected directly to the
mainboard of the ventilation unit.
The profi-air connection box consists of
a control board with various inputs and
outputs. The control board is incorporat-
ed into a plastic housing which is
installed near the ventilation unit.

6.1 Modbus (connection to the ventilation unit)
6.2 Fire/smoke alarm input
The Modbus connection is used to con-
nect the connection box to the main-
board of the profi-air 180 flat ventilation
unit. It is already connected in the deliv-
ery state.
The input can be used to connect the
fire/smoke alarm with a relay output.
When delivered, the contact is furnished
with a bridge. If this contact is interrupt-
ed by, e.g., a triggered fire/smoke alarm,
the control system deactivates the venti-
lation unit. In order to put the ventilation
unit back into operation, it must be com-
pletely disconnected from the power
supply for a short period of time.
Since the external control unit delivered
with the profi-air 180 flat ventilation unit
also uses the Modbus interface on the
mainboard, it must also be connected to
the clamping points of the connection
box on site. Please observe the colour
coding of the wires.
To use the function, the contact must be
connected to the break-contact relay
(see illustration), and the factory-provid-
ed bridge must be removed. If the relay
is in a “live” state, the contact is closed.
If the current at the relay drops, the con-
tact will be broken and the ventilation
unit will be deactivated. The J2 contact
is operated at a maximum of 24 V DC /
300 mA.
For information on the connection to the mainboard of the profi-air 180 flat ventilation unit, see installation
and operating instructions of the ventilation unit.

6.3 Humidistat input
profi-air room humidistats (Cat. no.
78300841) can be connected to this
input. If the set value at the room humi-
distat is exceeded, the control system
switches the ventilation unit to mode 3.
If the wiring is arranged in parallel, sev-
eral room humidistats can be connected
to the contact.
The digital input on the control board of the ventilation unit can also be used to connect the room humidistats
to the profi-air 180 flat ventilation unit. See profi-air 180 flat operating instructions.

6.4 Standby input
The input can be used to connect the standby switch to the ventilation unit.
If the system has been switched off over a longer period of time, this causes an increased risk of condensation in
the pipes, and/or might lead to moisture damage in the building.
