1 - SAFETY/HANDLING GUIDELINES
1.1 General information
Installation, start-up and maintenance operations for this equipment may be dangerous if certain factors particular to this
installation, such as the presence of electrical and live components and the installation location, are not taken into account.
Only trained, qualified installers and technicians, who have undergone specific training on the product in question, are authorised
to install and start up this equipment.
During any servicing operations, all the recommendations and instructions given in the maintenance brochures, on the labels or in
the instructions accompanying the equipment must be observed, along with any other applicable safety instructions.
- Observe all the regulations in the safety codes.
- Wear safety goggles and work gloves
- Handle heavy or bulky equipment with care when lifting, moving and setting down
1.2 Protection against electrocution
Only personnel qualified in accordance with the IEC (International Electrotechnical Commission) recommendations must be
allowed to access the electrical components. It is particularly recommended that all the electrical supplies to the unit are switched
off before any work is carried out. Cut the main power supply using the disconnect switch or circuit breaker.
Important: the V300 control system includes electronic components. These may cause or be subject to electromagnetic
disturbance if they are not installed and used in accordance with these instructions
Important: this equipment has been found to comply with the essential requirements of the directives in reference to the
following standards:

damage to your equipment.
Warning : the equipment must be connected to an electrical system that conforms to
the standards in force in the country (NFC 15-100 in France). It must be equipped with
protection against overcurrent, overvoltage and earth faults.
Warning : for your own safety, it is essential to switch off and disconnect the equipment from
the mains before carrying out any work on it.
Warning : the safety of this product is only guaranteed if it is used as intended. Maintenance
may only be carried out by qualified personnel.

2 - V300
CIAT's V300 control is designed for use with system-powered comfort units (AHUs, cassettes, etc.) in 2-tube, 2-tube/2-wire and
4-tube applications using recirculated air
It can be used to follow a time schedule (connected to the V300 zone timer as an option) and operate using a master/slave
function. It controls 230 V thermo valve actuators.
The V300 system comprises a controller integrated in the comfort unit and a user terminal for adjusting the setpoints and
operating modes.
The terminal is available in a wall-mounted wired version (to be connected to the controller by the installer), a flush-mounted
version (assembled and connected in the factory), and a radio-frequency version (terminal + receiver supplied in kit form)
Main functions:
- PI action
- Controlling a 3-speed or HEE fan, automatically or manually.
- Automatic heating/cooling switching with changeover sensor (2-tube application).
- 2 potential-free inputs for window switch, alarm or timer.
- 4 operating modes: Comfort/Economy/Frost protection/Off
Eubac certification
• The V300 controller is Eubac-certified under licence No.215472
• The corresponding CA values are as follows:
Applications: → 2-tube: Heating: 0,1 Cooling: 0,1
→ 2-tube/2-wire: Heating: 0,2 Cooling: 0,1
→ 4-tube: Heating: 0,1 Cooling: 0,1
• Labelling: AA
Note:
- These values are obtained with the CIAT NTC 10k Ω return air temperature sensor at 25°C
- These values can be viewed on the Eubac certification website: http://www.eubaccert.eu
General danger : If the instructions are not followed, there is a risk of equipment damage.
Electrical danger : If the instructions are not followed, there is a risk of electrocution and
injury.
Read the instructions in this manual.
Part of Class II equipment
Protective device Devices that protect against overloads, short circuits and earth faults must conform to standard NF C 15-100,
and must be part of the building in which the equipment is installed. The circuit breaker must be designed for a nominal current
in Amperes that corresponds to the CIAT equipment model purchased.
Waste disposal by users in private households within the European Union.
This symbol, either on the product or its packaging, indicates that the product must not be disposed of in ordinary
household waste. Instead, it is your responsibility to ensure that you dispose of your waste by taking it to a
designated recycling point for electrical and electronic devices. Separating your waste for recycling during disposal
helps preserve natural resources, protect the environment and safeguard health. To find your nearest recycling
centre, contact your local council, waste disposal service or the store from which you purchased the product.

When exiting the heating or cooling mode, the fan continues to operate for 2 minutes, thereby ensuring post-ventilation of the unit.

The control is Proportional and Integral. It controls the valve(s), the electric heater and the ventilation speeds (3 speeds + Auto
position) simultaneously.
3 - OPERATION
The potential electric heater power is modulated by a time-proportional signal using a 4-minute time base.
All calculations take place in the controller. The control terminal is used to adjust the temperature setpoint, switch between
automatic and manual ventilation, switch the unit on or to standby and, if applicable, to measure the room temperature.
The connection between the terminal and the controller is a 4-wire connection (2 shielded twisted pairs) with the shielding
connected to the comfort unit earth. (see pp.10 & 16)
Regulation on the air:
The regulation V300 also allows a functioning on the air (without gate(crack))
- In this case, the use of pumps of condensats on devices equipped with this mode of regulation stays of the responsibility of the
customer and/or the installer in case of dysfunction of this pump (risk of overflowing of the tub(ferry,high school diploma) of the
condensats of in the permanent irrigation of the cold battery(drum kit)).
- For vertical units equippedwith this control principle, the effect of the continuous radiation from the exchanger coil on the sensor
vill not enable the control system to function correcty. It is the customer's responsibility to find a suitablelocation for optimum
positioning of the sensor and satisfactory operation of the units.
