6 Operator control unit
The settings made on the ventilation unit
are performed via an operator control
unit. Control and operation of the venti-
lation unit is performed via the „PI-HMI“
control unit for surface mounting.
The touchscreen makes performing set-
tings simple. All important operating
data are displayed.
The control unit is normally
installed in the living area
and should be suitably positi-
oned. Thermal source areas, radiators,
direct sunlight etc. have to be avoided on
account of their temperature influence!
