CONNECTION TO THE POWER SUPPLY
At the external input (230 V/50 Hz or 400 V/50 Hz) there
must be a circuit breaker built into the fixed power supply
network which breaks all phases of the network.
The external circuit breaker must be located so that it is
freely accessible for quick disconnection.
The protection tripping current shall correspond to the
maximum consumption current of the control unit, the
ventilation system and the heater.
The control unit is connected to a 240V or 400V supply
(3x2.5 or 5x2.5) depending on the model and application of
the unit.
The ventilation system is connected to the control unit
with 4x0,75 or 6x0,75 wires, 2 supply (L,N) wires, 2 exhaust
(L,N) wires and 2 mini-heat (L,N) wires (optional).
To connect the supply air afterheating, 5×1,5 (up to 3,6
kW) 5×2,5 (up to 6,0 kW) conductors are used.
To connect the overheating sensor of the heating element
2x0.75 conductors are used.
To connect the temperature sensor in the supply duct,
2x0.75 conductors are used.
The system is controlled by remote control, mobile app,
details can be viewed in the brief user manual.
