CIAT COADIS LINE 600 Manual De Instrucciones página 43

Use a screwdriver to undo, but not remove, the lateral retaining screw on the
electrical box casing (Fig. 13 - a).
● Modifying the motor speeds:
Always use a screwdriver when performing cabling operations.
COADIS LINE offers a choice between two types of motor technology:
Asynchronous and Brushless (low consumption).
- The asynchronous motor:
To optimise the unit's performance and depending on the type of control used.
The unit has five speeds numbered V1 to V5 connected to the terminal block in the
electrics box (V1= low speed and V5= high speed).
The customer must cable the speeds for the thermostat at the top of the terminal
block between V1 and V5.
To open a connection point and change the cabling (Fig. 14):
- Place the end of a flat-blade screwdriver in the hole located just below the cable
to be removed.
- Release the cable and move it to the marker for the desired speed.
- Place the screwdriver again in the hole just below the desired speed, insert the
cable and remove the screwdriver; this ensures a secure contact.
Repeat the procedure for the remaining customer speeds.
IMPORTANT: the wires coming from the motor and connected to terminals V1
to V5 must never be interconnected.
IMPORTANT: i t is essential to refit the electrical box casing once all the cabling and
adjustment operations are complete.
- The (HEE) brushless motor:
This has a motor speed electronic control unit which uses a 0-10V control signal or
3-speed on/off control (to be selected by the customer depending on the controller or
thermostat used with the unit).
- Controller or thermostat for 3-speed on/off control:
• S witch on the unit and select the ventilation speed to be modified using the
thermostat.
• U se the "CIAT speed control unit" accessory supplied as an option to adjust each
speed (rpm) in accordance with the instructions included with the unit.
- Controller managing a 0-10V control signal:
• T he 0-10V setpoint voltage information is issued by the controller itself. Refer to
the operating and configuration instructions supplied by the manufacturer.
