1 CONSTRUCTIVE FEATURES

< The unit’s bearing structure is made from galvanised steel sheet, externally and internally insulated with heat and soundproofing material.

This structure houses the main components (heat exchanger, fan drive assembly and condensate drainage pump) and is designed for letting outdoor air in and distributing air to an adjacent room.

< Statically and dynamically balanced centrifugal fan with backward-curving blades, mounted directly on the electric motor. The blades are designed for very low-noise and efficient operation also at slow speed.

< 230V electric motor with thermal protection on the windings. It has 4 speeds to optimise unit performance in terms of noise and energy.

< High efficiency heat exchanger made with copper piping and aluminium fins, complete with air vent valves.

< Plastic water drip tray moulded inside the polystyrene air directing structure.

< Condensate drainage pump with a useful head of 250 mm, complete with float and a level switch for controlling the level of condensate inside the tray and alarm management.

Operating logic assures a lowering of fan speed when the drainage pump is working (float switch trips, first level) to facilitate the flow of condensate from the exchanger fins.

< Electrical components housed in an external box, consisting of the electronic board that controls the unit and a relay for pump operation.

The box is located by the side of the water connections to reduce the need for installation clearance.

< Plastic water drip tray moulded directly inside the polystyrene air directing structure.

< Air intake and outlet polystyrene panel, RAL 9001 colour, preformed high density polystyrene foam air passages complete with air suction grid, a washable polypropylene filter and adjustable air outlet fins. The panel differs between the version configured for a wired controller, where the louver position is manually adjusted, and the version with infrared remote control where adjustment is motorized. On the front there is also a series of LEDs indicating the operating status of the unit.

2 CONSTRUCTION VERSIONS:

< Cassette fan coils (2 pipe systems), cable control (optional). < Cassette fan coils (4 pipe systems), cable control (optional).

OpERATING LIMITS•Watercircuit - Minimum temperature of water inlet: 4°C. - Maximum temperature of water inlet: - main heat exchanger: 70°C - secondary heat exchanger: 80°C

Note: To ensure optimal comfort (homogeneous air temperature in the room), it is recommended not to exceed an exchanger inlet temperature of 55°C:

- Maximum operating pressure: 16 bar.

•Roomair: - Minimum temperature of room air intake: 5°C - Maximum temperature of room air intake: 32°C

Warning: during a shutdown for installation, in the event of a connection to a fresh air intake or an ambient temperature close to 0°C there will be a risk of the pipes freezing. Provide drainage for the plumbing circuit.

10 ELECTRICAL CONNECTIONS

GENERALITIES• Class1Unit.• The electrical installation must comply with current standards and regulations (paying particular attention to standards NF C 15-100, CEI 364).

DETAILS OF CONNECTIONS• Several cable clamps are provided to secure the cables at the entry to the control panel.• Connect the cables to the terminal boards provided.• Make sure that the cables are properly connected to the terminals. Improper connection of cables may cause functional problems, superheating and

fire.• When replacing the panel cover, be careful not to damage the cables.

pOWER SUppLY• 230V/1+Ground/50Hzwithprotectiondeviceanddisconnector(notsupplied),inaccordancewithcurrentregulationsandnorms.Protectionmust

be assured by a bipolar switch (not supplied).

Note: The unit is designed to be connected to a main power supply with a TT (earthed neutral) or TN-S earthing system according to NF C 15-100. For a neutral IT system (isolated neutral), provide differential protection.

MYCOMFORT BASE - wall-mounted microprocessor control, GALLETTI model MYCOMFORT BASE having the following main features:- Room air temperature reading and adjustment - Water temperature reading (water sensor as an

optional)- Manual and automatic adjustment of fan speed- Manual and automatic switching of heating and

cooling mode depending on the water temperature within the heat exchanger or on the room temperature, with a neutral zone that can be selected in the range from 2° to 5°C.

contacts)- Serial port for Bus connectionThecontrollerisequippedwithalargedisplay(3”)toshowandsetallthefunctions of the unit.Usingtheinstallationkitavailable,MYCOMFORT can be mounted on the unit

SW - Water temperature sensor for microprocessor controls model MYCOMFORT Directly connected to the microprocessor control model MYCOMFORT to measure the water temperature through the heat exchanger. If the temperature detected is less than 17°C, the unit will operate in the cooling mode and the controller will use the summertime temperature scale (19 - 31°C); if the temperature detected is greater than 37°C the unit will function in the heating mode and the controller will use the wintertime temperature scale (14 / 26°C). If the temperature detected by the probe is in the range of 17°C to 37°C, the controller will inhibit operation of the fan coil unit.

Kp - power interface for connecting in parallel up to 4 fan coil units to one controlThe KP interface is used to control up to 4 units (connected in parallel) by means of a single control panel.Suitable for mounting on DIN guides, usually installed in electric control panels, it can be used with all IWC versions .

LED503Recess wall-mounted microprocessor controlThe proposed microprocessor control panels for Galletti indoor units is completed by the LED503 command with LED display that is designed for recess wall mounting.CONTROLLERThe control software developed by the Galletti Software Dept., features:- manual selection of fan speed;- automatic selection of fan speed

according to the difference between the set temperature and the room air temperature;

- manual selection of heating/cooling operating mode;- automatic selection of heating/cooling operating mode;- control of 1 or 2 ON/OFF valves;- control of additional heating element;- on board timer function to detect the actual ambient temperature;- reading of air ambient temperature, set point, fan speed and mode selection

on the LED display.

TD4TWall-mounted thermostat switch and summer/winter selecting switch for 2 or 4-pipe systems with valvesControl panel for wall mounting, complete with speed switch, electromechanical thermostat and summer-winter selector. It governs the adjustment valves, if present. Fan speed control and room temperature control:- manual operating speed switching;- room temperature control in both the heating

and cooling modes for 2 and 4 pipe systems, achieved by switching the fan off and on, at the manually set speed and opening and closing the regulation valves.

3-way motor driven valve and 4x2 motor driven valve kitThe kit includes:- Brass 3-way valve / 4 connections with built-in by-pass, maximum operating pressure 16 bar;Electrothermal ON/OFF actuator featuring:- power supply: 230 V- ON/OFF function (or modulating)- total opening time: 4 minutes

NOTE:The4X2valvemakes itpossible toconvertwhatwasoriginallya2-pipeunit intoa4-pipeunit.Thekit features twospecial“4x2”valves, twoactuators (on/off or modulating, depending on the valve kit code) and pipe kit. The installation is illustrated in the figures 1,2,3, and 4.Hydraulic kit for the installation of the valve on the heat exchanger.Pressure drops of the valve/hydraulic kit assembly are calculated using the following formula :

∆PW = (QW / KV)2

where:∆PW pressure drop in kg/cm2

QW water flow rate in m3/hKV water flow rate coefficient of the valve obtained from the following table
