  • Page 5: Description Of The Components

    DESCRIPTION OF THE COMPONENTS Base The unit is characterised by a reinforced, integral metal structure with insulation expanded polystyrene obtained from injection moulding for purposes of noise reduction and air routing. The load- bearing base is in galvanised sheet steel varnished with polyester powders.
  • Page 6 Basin Basin closing off the unit. Made of injection co-moulded polystyrene to avoid thermal dispersion and the formation of condensate, it conveys conditioned air towards the louvres from condensate drip basin. The intake conveyor equipped with a protective grille that impedes access to the moving fan.
  • Page 7 Three-way valve Internal 3-way valve, of the all-or-nothing type, with fast connection actuator visual signalling position, assembled standard heating/cooling coil, powered with a voltage of 230V ~ 50Hz.
  • Page 8 Fan unit The fan unit, with the latest axial-centrifugal fan designed obtain sound emissions, is dynamically and statically balanced coupled with 4-speed motor. The fan unit can be easily accessed for cleaning and maintenance.

  • Page 15 Intake and delivery grille unit The grille is part of the GLL range unit (obligatory accessory). The form and opening of the intake slats were developed in order to have the best possible distribution of the air, both when functioning in winter as well as in summer. Suction is made via the central grille, and delivery via the perimeter openings that can be manually oriented (or, only for version GLL10M, by means of the remote control).

  • Page 26: Plumbing Connections

    CONNECTIONS PLUMBING CONNECTIONS The plumbing connections are made with flat fittings complete with seal gaskets (supplied). In the 4-pipe version of the unit, it is essential to install the VHL1 valve accessory. For this purpose use the supplied gaskets. The accessory has gaskets for connection to the system. Information for the correct installation of the VHL1 valve is contained in the accessory instruction booklet.

  • Page 27: Condensate Discharge Connection

    CONDENSATE DISCHARGE CONNECTION During cold functioning the indoor unit removes humidity from the air. The condensate water must be eliminated by connecting the appropriate discharge coupling to the piping of the condensate discharge system. The polystyrene basin has a hole permitting the condensate to be fully run off (this is also useful in the event of disassembly).
  • Page 28 CONNECTIONS FOR THE DELIVERY OF TREATED AIR TO AN ADJACENT ROOM The unit can be connected to a conduit (diameter 100mm) for delivering treated air to an adjacent room via the circular KFL flange accessory. The application of the flange requires a hole to be opened up on the side.

  • Page 46 Using the system This section shows the selection of the functioning mode by the user via remote control, and the configuration of the system by the manufacturer and installer by means of dip switches. Compatibility of remote controls The table shows the compatibility between remote controls and board codes and replacements: CRMC- A698JBEZ CRMC- A360JBEO (old) (new)
  • Page 47 Emergency setting and receiver visualisations If necessary there is an “AUX” key on the grille receiver, that activates the "Auto- Emergency" mode. In this mode, the machine functions automatically dependent on the ambient temperature read the moment the AUX key is pressed.
  • Page 48 Setting the dip-switches on the board. The microprocessor of the board recognises the type of machine from the way the dip-switches are set. The configurations that can be set are: FCL cassette-type fan coil FCL cassette-type twin fan coil It is also possible to configure machines ECL, EXC, CUCCIOLO, EXM, ANCX, but this procedure lies outside the scope of this document.

  • Page 51 Control logics Cooling mode (fan coil) By means of the remote control it is possible to set the cooling mode and set an operating temperature. If the fan speed is set in automatic mode the system selects the fan speed for itself and decides the opening of the water valve depending on the difference between the operating temperature set by the user (setting) and the temperature measured by the ambient probe.
  • Page 52 In the case of the 4-pipe configuration, in the cooling mode, the control board rather than the generic solenoid valve VS, will control the cooling solenoid valve VSF (shown in brackets in the diagrams above) while the heating solenoid valve (VSC) is closed. Heating mode (fan coil) By means of the remote control it is possible to set the heating mode and a reference temperature.
  • Page 53 In the 2-pipe configuration the heating mode is activated by controlling the general solenoid valve Y1, while in the 4-pipe configuration the heating water solenoid valve Y2 is controlled with the same logic, and closing the cooling water valve (that in the 4-pipe case is Y1) as soon as the heating mode is imposed.
  • Page 54 Motorised louvre From the remote control, the swing key will put the louvre into motion and this will continue to rotate until the next (stop) command. The louvre also stops when the ventilation stops (e.g. because the setting has been reached). Ambient probe The reading of the temperature by means of the ambient probe is continuous with the ventilation in operation.
  • Page 55 Thermostat-controlled heating ventilation: pre-heating of electric heater . electric heater used (whether as a supplement or replacement) the timing takes into account the need to prevent the electric heater remaining at high temperatures for too long. When the electric heater is turned on, a pre-heating phase begins (30 seconds at V ) before arriving at full capacity.
  • Page 56 Water control (optional) It is possible for a probe (SW 4) to be installed for reading the temperature of the water circulating in the exchange coils. Below there is a detailed description of a control logic for enabling/disabling the loads on the basis of the temperature read by the water probe and the functioning mode set from the remote control.
  • Page 57 Auto functioning (from the remote control) In this functioning mode the user does not set the temperature; the fan of the indoor unit functions in Automatic mode. By activating the "AUTO" mode on the remote control, the temperature SET disappears and the fan works in automatic mode.
  • Page 58 Autotest This section shows the two autotest procedures: from infrared receiver and wired panel. It is possible to activate the autotest mode by powering the machine, keeping the AUX key pressed down for about 5 seconds. In this case, the board makes two beeps by means of the buzzer, and is positioned at step 0.
  • Page 59 Alarm management The management of the alarm situations will be as follows: When an anomaly arises the machine will be put in stop status (Pre-alarm) and the anomaly is counted. There are two possible situations at this point: the pre-alarm remains for a time in excess of the maximum value (Time-out): in this case the alarm is taken to the Alarm state definitively.

  • Page 60: Alarm Display

    Alarm log display It is also possible to display the last anomalies that arose and were automatically reset. For all the receivers, the procedure is as follows: place the machine in standby and press the AUX key for at least 5 seconds (a triple beep indicates that this function is being used).
  • Page 61 Probe display (with infrared receiver) It is possible to display the values of the temperature probes captured by the electronic board. To do this it is necessary to follow the following procedure: set OFF from the remote control (or by pressing the AUX key). press the AUX key for 5s.
