Water piping can enter either from the floor or from the wall. Leave the space shown in the figure. The unit coil can be supplied with water connections positioned as requested. However field conversion of the connections is achieved quite simply as follows: Remove the control box panel; Unscrew the 6 self-threading screws and remove the front drain pan; Unscrew the two screws holding the heat exchanger to the structure, necessary for earthing the coil; Remove the coil by unhooking it with the rubber tabs and turn it horizontally through 180. Place the coil into its new position by hooking it using the special rubber tabs; Refit the front drain pan with the 6 selfthreading screws; Retighten the two screws holding the heat exchanger to the structure, necessary for earthing the coil; Position the control box panel opposite the coil connections. Pass the sensor through the special hole and seal with sealing material in the tangential fan versions; Position the control into the tabs provided,, blocking it with the supplied metal plate (see paragraph Controls). Change the position of the condensate drain closing plug of the drain pan and put it on the same side of water connections.

Remove the control box panel casing by means of the fixing screw/s. Before proceeding with the unit connection to the mains supply locate live L and neutral N, then make connections as shown in the wiring diagram. Ensure that the mains supply connection is made through a switch that disconnects all poles, with contact gap of a least 3 mm. All fan coil connecting cables as well as accessory wires must be of the H05 VV-F, type with PVC insulation according to the EN 60335-2-40 standard. For the unit power supply, it is recommended to use cables with a minimum size of 3x1.5 mm2. For units equipped with electric heater, refer to table III (Technical data of electric heater) for sizing power supply cables. Make sure that connection to the mains supply of the electric heater is made through a switch with contact gap of 3 mm. After making all electrical connections do not forget to close the control box panel using the special protective cover and to fix it by means of the screw/s previously removed.

Control box panel

The control box panel is always positioned opposite the water connections. Two different control box panels are available: one for a unit without electric heater, and one for a unit with electric heater. Inside each control box panel there is a terminal block for the electrical connections (see wiring diagrams). After connections have been completed, cables must be secured with the cable holders supplied. If the unit is fitted with an electric heater, this must have a separate power supply.

Quadro elettrico

Il quadro elettrico si trova sempre posizionato dalla parte opposta a quella degli attacchi idraulici. Sono disponibili due tipi di quadro elettrico, uno per unit senza elemento riscaldante, laltro per unit con elemento riscaldante. Allinterno di ogni quadro elettrico presente una morsettiera alla quale effettuare i collegamenti elettrici (vedi schemi elettrici).

Frostschutz Diese Funktion sorgt dafr, dass die Temperatur in Rumen, die lnger unbenutzt bleiben, nicht unter 7C abfllt. Wird diese Temperatur erreicht und ist die Frostschutz-Funktion durch einen Kippschalter (bei der Installation eingestellt) an der Elektronik-Platine freigegeben, aktiviert die Regelung das (die) Ventil(e) und stellt die hohe Ventilatordrehzahl ein. Die FrostschutzFunktion wird, wenn sie freigegeben ist, aktiviert, selbst wenn die Regelung sich in der AUS-Stellung befindet.
Proteccin frente a heladas Esta funcin impide que la temperatura sea inferior a 7C en habitaciones que estn desocupadas durante perodos largos de tiempo. Cuando se alcanza esta temperatura y si se ha activado (durante la instalacin) la funcin de proteccin frente a heladas mediante un conmutador Dip, situado en la tarjeta electrnica (ver apartado configuracin de conmutadores Dip), el control activa la(s) vlvula(s) y pone el ventilador a velocidad alta. Si est seleccionada, la funcin de proteccin frente a heladas se activa incluso si el control est en posicin OFF.
Energy saving This function is especially useful when air conditioning at night or in rooms where the user is likely to be absent for a longer period of time. In this case, pushing button raises the temperature during cooling by 4C and lowers it during heating by 4C. Enabling this function (yellow LED ON) cuts out other displays.
Energy saving (risparmio energetico) Questa funzione particolarmente utile durante il funzionamento notturno o negli ambienti climatizzati nei quali si suppone di dover rimanere assenti per un certo periodo di tempo. In questo caso agendo sul pulsante possibile aumentare di 4C la temperatura durante il funzionamento in modalit raffrescamento e di ridurre di 4C la temperatura durante il funzionamento in modalit riscaldamento. Labilitazione di questa funzione (LED giallo inserito) esclude le altre visualizzazioni.

Seasonal changeover

Manual Selection of heating/cooling is done manually by pushing the button on the control. Centralised (only for type A control) Centralised seasonal changeover can be done in two ways: - by a switch located on the central control panel that allows heating/cooling mode changeover (to be made by the installer). - by a temperature sensor located in contact with the entering water pipe (accessory). In this last mode, fan coil operation is driven by the control, in cooling or heating, depending on the temperature read by the sensor. Switch and sensor operate on 230V power supply, so both must be adequately insulated. If the seasonal manual changeover button is pushed while the centralised changeover mode is activated, the corresponding LED will briefly flash while maintaining the activated mode. In any case, centralised changeover takes priority over local changeover.
