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.

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 (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:

•

Switch on the unit and select the ventilation speed to be modified using the thermostat.

•

Use 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:

•

The 0-10V setpoint voltage information is issued by the controller itself. Refer to 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.

IMPORTANT NOTE: (HEE) Brushless motor

The electrical connection for

CIAT

Comfort Units must be made in compliance with international standard IEC

60364 (Electrical Installations for Buildings).
The leakage current on all our comfort units conforms to the requirements of IEC 60335-2-40 (Safety of household

and similar electrical appliances):

■ Complete comfort unit (with electric heating elements) equipped with a multi-speed motor: maximum leakage

current = 2 mA.

■ Complete comfort unit (with electric heating elements) equipped with an HEE motor (brushless

technology): maximum leakage current = 4,5 mA.

Electromagnetic compatibility in accordance with Emission Standard 61000-6-3

(EN55014-1, Tool class)

and Immunity 61000-6-1

(Residential, commercial and light industry class).

The unit's compliance with the above standards does not guarantee the compliance of the

installation as a whole (several other factors not relating to the unit may be involved). As a result,

the installer must observe the applicable recommendations in order to guarantee compliance.

Electrical safety:

To ensure user safety, earthing is compulsory.
The installation must be equipped with a device to protect against earth faults.
A disconnect device must be built into the installation between the supply and the 230 VAC power network, and

must be easy to access. The disconnect device must simultaneously disconnect the two poles (phase and neutral),

and have a distance of at least 3 mm between the contacts, in compliance with the installation instructions.
The mains power cable must have 3 conductors (blue, brown, green/yellow) and its cross section and type must

comply with the specifications set out by the applicable EN or IEC standard. Refer to the selection sheet or the

name plate to determine the maximum input current. The cable must be fed into the box via the circular hole fitted

with a protective grommet and secured in the dedicated strain relief.
Its maximal diameter must be 12 mm. It must be clamped at low speed with a torque not exceeding 0.8 Nm.
