CONNECTION 0-10 V SIGNAL (BUILDING MANAGEMENT SYSTEM
APPLICATION)
With 1-10V the flow can be set steplessly between the minimum and maxi-
mum flow of the ventilation unit.
This corresponds to the following values:
DX4
1 V 40 m³/h
1 – 10 V Linear correlation
10 V 400 m³/h*
*the indicated air flows are in function of and dependent on the total pressure loss of the ventilation
system to be overcome.
Before starting any work, make sure that the ventilation unit is de-energized.
To connect a 0-10 V signal, the cover on the ventilation unit must be
opened in the correct way in order to reach the circuit board. To do this,
remove the screw and tilt the cover plate away from the ventilation unit.
Then a correct cable must be guided to the circuit board via the grommet
provided for this in the ventilation unit. Finnaly, connect the control signal
to terminal X26 "Building management system connection", according to
the following diagram.
