Sequence of operations to be performed to install the various components:
(1) Install the FCXI-P fan coil:
this unit is the only fan coil of the zone (MASTER). The unit must be appropriately
installed electrically and hydraulically following the instructions provided in the fan coil documentation; the duct
must be properly sized based on the features of the fan coil.
(2) Install the VMF-E18 thermostat:
to manage the INVERTER fan coil via a VMF network, a VMF-E18 thermostat
must be installed on the fan coil. This accessory allows to connect the control interface for the zone master (in the
proposed example, the interface is represented by a VMF-E4), and to connect the thermostat to the VMF system
serial network (for detailed information on installation and connection of the VMF-E18 thermostat, refer to the
specifi c documentation). The following is a summary of the operations required for installation of the proposed
example:
(a) remove the service terminal board from the side of the fan coil;
(b) mount the box of the VMF-E18 thermostat in place of the service terminal board;
(c) using the connection cables previously detached from the terminal board, connect the thermostat with the
inverter control module (we recommend referring to the wiring diagrams of the unit to perform this connection).
(d) earth the VMF-E18 thermostat;
(e) connect the power supply to the VMF-E18 thermostat;
(f) connect the air probe to the VMF-E18 thermostat (the air probe is indicated as SA in the wiring diagrams);
(g) connect the water probe to the VMF-E18 thermostat (the water probe is indicated as SW in the wiring diagrams);
(h) connect the wall-mounted VMF-E4 control panel (this connection can be made even if the box of the VMF-E18
thermostat is closed);
(i) connect the VMF-E18 thermostat to the VMF network (these connections will be specifi ed more in detail in the
chapter VMF NETWORKS SERIAL CONNECTIONS).
ATTENTION: the VMF-E18 thermostat boards have dip switches which MUST be set correctly based on the
features of the fan coil to which the thermostat is connected. Refer to the thermostat documentation to set
these dip switches correctly.
(3) Install the wall-mounted VMF-E4 panel:
to manage the FCXI-P fan coil directly from the room of Zone A, the
wall-mounted VMF-E4 panel must be fi tted (refer to the specifi c documentation to install the panel).
