The unit is connected to the KVR-T controller with two cable channels. In ventilation mode all the connected units operate in air extract mode (the JMP1 jumper on the circuit board is in Flow out position) or in
supply mode (the JMP1 jumper on the circuit board is in Flow in position).
The electric connection is performed with a five-wire cable. The wires are marked in compliance with the delivered cable for easy installation. The minimum conductor cross section is 0.25 mm2. Power supply
230 V / 50 Hz must be provided both to the KVR-T control unit and to the ventilation unit (socket connectors 31-21 in each case).
