The automatic control system is designed for controlling ventilation systems of various configurations.
The control system controls basic ventilation system components, such as supply and extract fans, heat exchanger, air heater, air cooler,
air humidifier, air mixing chamber, air dampers. The automation unit has a configurable controller with installed software. The controller
can be individually configured for each ventilation system. The control panels are rated for non-stop operation.
THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED
PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT
THE APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED
PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED
ACCESS BY UNATTENDED CHILDREN.
PURPOSE
For detailed description of the automatic control system functions please refer to the controller’s manual.
Please ask the ventilation unit seller to provide the manual.

INSTALLATION OF THTUNE CONTROL PANEL
For installation of the back side of the control panel use a mounting box with a minimum diameter 65 mm and installation depth 31 mm.
1. Detach the front side of the control panel from the back side using
a screwdriver.
2. Disconnect the 4-pin connector from the front side of the control
panel.
3. Complete the electric connection in compliance with wiring diagram.
4. Fix the back side of the control panel in the mounting box using the supplied screws.
5. Re-connect the 4-pin connector.

CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER’S LABEL.
• The unit is rated for connection to single-phase 230 V/50 Hz or three-phase 400 V/50 Hz power mains (refer to Technical data) in
compliance with wiring diagrams.
• The unit must be connected to power mains using durable, insulated and heat-resistant conductors (cables and wires). The actual wire
cross section selection must be based on the maximum load current, maximum conductor temperature depending in the wire type,
insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the circuit in
the event of overload or short-circuit. The position of the external automatic circuit breaker must ensure free access for quick power-
off of the unit. The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to
the “Technical data”section). The recommended trip current of the circuit breaker is the next current in the standard trip current row
following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set and can be
ordered separately.
DO NOT LAY THE VENTILATION UNIT POWER CABLE IN CLOSE
PROXIMITY TO THE CONTROL PANEL CABLE!
DO NOT COIL THE CABLE FROM THE CONTROL PANEL IN LOOPS WHILE
LAYING IT.
Route the cables to the control unit via the cable glands on the air handling unit.
Complete the electric connections in compliance with external wiring diagram via the terminal blocks in the control unit.
