An earth connection is compulsory. CIAT shall not be liable for incidents resulting from faulty or non-
existent earthing. Always follow the wiring diagram delivered with unit.
To access the electrical terminal block:
Disconnect the unit from the electrical power supply
Use a Phillips screwdriver or a size 7 Allen key to undo the 2 screws securing the electrics box
cover (Fig.10).
Always use an electrician's flat-blade screwdriver.
COMFORT LINE
TM
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 wire 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. 11):
-
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 in the hole again 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.
The wires coming from the motor and connected to terminals V1 to V5 must never be interconnected.
It is essential to refit the electrical box casing once all the cabling and adjustment operations are
complete.
■
The brushless motor:
Depending on the controller or thermostat fitted with the unit, the motor may be controlled by a 0-10V control signal
or 3 speed on/off control.
- With a controller managing a 0-10 V control signal: The 0-10V setpoint voltage information is issued by the
controller itself. Refer to the operating and configuration instructions supplied by the manufacturer.
-
With a controller or thermostat managing a 3-speed on/off control: Depending on the controller or thermostat,
use the thermostat to select the ventilation speed to be modified, or use the "
CIAT
speed control unit" accessory
supplied as an option. It is possible to change the speed (rpm), following the instructions supplied with the
speed control unit.
To prevent any risk of damage, never connect several asynchronous or brushless fan coil unit
motors in parallel for the same thermostat.
IMPORTANT NOTE: Brushless motor
The electrical connection for
CIAT
Comfort Units must be made in compliance with international standard IEC
60364 (Electrical Installations for Buildings).
