OVERALL DIMENSIONS MOUNTING PLATE DIMENSIONS WIRING DIAGRAMS Make the electrical connections with the power supply disconnected, in accordance with current safety regulations. Check that the mains electricity supply is compatible with the voltage shown on the unit rating plate. Each fan coil requires an individual electric socket and a switch with a suitable safety fuse. --------- Factory wiring - - - - - Field wiring Each fan coil requires an omnipolar main switch classified as overvoltage category III to be mounted on the power supply line.
WIRING DIAGRAMS MASTER / SLAVE NETWORKS ABBREVIATIONS The FM fan coil units are equipped with a PCB suitable for the implementation Ts = set temperature of master/slave networks with up to 32 units. Tr = Room temperature Depending on the control panel used on the master unit it is possible to Ti1 = convector chilled water temperature implement two different types of master/slave control.

MASTER / SLAVE NETWORKS Slave unit function The slave unit receives data referring to its settings from the master unit. The slave unit can be set locally on a desired setting by means of the local controller, provided there are no subsequent changes to the settings of the master unit. The slave units can be set individually for switching on and off via the timer using the remote control or the wall-mounted control.
WALLPAD Wall-mounted cable control equipped with a large display to show all the functions and to control each fan coil unit of a master/slave system. WALLPAD is supplied with cable for the connection to the fan coil unit. Area of temperature display Display of operation Display of Fan speed Display of room or selected...
WALLPAD THE OVERALL DIMENSIONS ARE SHOWN BELOW INSTALLATION REqUIREMENTS Select the position of the high wall-mounted unit based on the following considerations: The air inlet and outlet front part must be free of obstructions. The air should flow freely. The wall the unit is mounted on must be sufficiently rigid so as not to resonate and produce noise. The position should permit easy access for installing the connecting water pipes and in a convenient place for drainage.
INSTALLATION REqUIREMENTS ROUTINE MAINTENANCE Clearance for maintenance and repairing is shown above The material must undergo maintenance in order to retain its characteristics ** All dimensions are in mm. over time. Lack of maintenance may have the effect of voiding the product The signal receiver on the unit must be kept as far away as possible from warranty.
MODBUS The protocol implemented on the fan coil is Modbus RTU (9600,N,8,1) on RS485.
