ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
The unit is rated for connection to single-phase AC 120 V
~
60 Hz power mains.
Connect the unit to power mains using durable, insulated and heat-resistant conductors (cables and wires). The total minimum cross
section for the power cable must be not less than 0.5 up to 0.75 (No. 20÷18 AWG) mm2 and 0.25 mm2 (No. 23 AWG) for the signal cables.
The above wire cross section value is tentative. The actual conductor cross section selection must be based on the wire type, maximum
wire temperature, insulation, length and installation method.
Use copper wires only for all the electric connections!
Connect the unit to power mains via the terminal block in compliance with the wiring diagram and terminal designation.
Connect the ventilator to power supply through an automatic circuit breaker with electromagnetic trip integrated into the home wiring
system. The rated trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit, refer to the
rating plate on the unit casing.
The ventilator design enables connection of the external units with NO contact, such as external CO2 sensor, humidity sensor, switch, etc.
When the NO contact of the external device is closed, the ventilator switches to the maximum speed.
It is possible to connect an analogue sensor with output voltage 0-10 V to the ventilator
The diagrams below show two options for connecting the ventilator to the power supply, depending on the terminal arrangement on
the board.
Use the diagram that corresponds to the terminal arrangement in your ventilator.
