An operating display (lamp, contactor, etc.)
can be connected to the control circuit board
for an external monitoring of the ventilation
unit by a building supervisor, for example.
The "k1" potential-free relay contact can be
found on the control circuit board for this
purpose.
Relay contact "k1" is closed when
the ventilation unit is running.
The maximum load-bearing capacity
for relay contact k1 = 3A / 250 V AC,
2A / 30 V DC
