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.
it is essential to refit the electrical box casing once all the cabling and
adjustment operations are complete.
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).

speed (rpm) in accordance with the instructions included with the unit.
- Controller managing a 0-10V control signal:
the operating and configuration instructions supplied by the manufacturer.
If electric heaters are used, the lowest speed setting should never be
below 400 rpm.
To prevent any risk of damage, never connect several asynchronous or brushless
motors for different units in parallel on the same thermostat.
The electrical connection for CIAT Comfort Units must be made in compliance with
