ELECTRICAL WIRINGS
CONNECTIONS TO THE BOARD
• The installation of the VMF-E0X kit
requires that the standard control board
is removed from the fancoil.
• Mount the thermostat housing to the
side of the fan coil units, on the con-
nections that were of the control board.
• Remove the cover of the thermostat
housing.
• WARNING: make an earth connection
for the thermostat board. It is
compulsory to tighten the screw that
fixes the thermostat box on the side of
the fan coil, as this is what allows the
earth connection of the entire system.
• Connect the power supply cables.
Warning: respect the L and N polarities.
• Connect the electric cables of the
electric motor. Respect the speed
sequence: if the motor has 4 or more
speeds, choose the 3 required.
• Connect the electric cables of the air
temperature probe (SA).
• Connect the electric cables of the water
temperature probe (SW).
• Connect the cables for the external
contact (if envisaged).
• Connect the cables for the microswitch
(if envisaged).
• Connect the TTL mains cables (if
connected to the mains).
• Connect the cables of the control panel
(if envisaged).
• Check all the connections and relative
cables are well fixed.
• Arrange the cables so there is no risk
of them being cut, crushed, jerked,
scraped, or generally damaged.
• Check the board fuse is undamaged and
possesses the necessary features.
• Close the box with the cover.
• Fix the power supply cables and valve
cables using the cable clamp.
WARNING: Keep separate electri-
cal connections from water con-
nections. Water connections and
drain should be on the side oppo-
site of the electrical connections.
DANGER: It is compulsory to tighten the screw that fixes the thermostat box on the
side of the fan coil, as this is what allows the earth connection of the entire system.
