CONNECTIONS TO THE BOARD
• The installation of the VMF-E1X 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.
DANGER: it is compulsory to tighten the
screw on the side of the fan coil, as this
is what allows the earth connection of
the entire system.

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.

secondary water temperature probe
(SW1) (in 4-pipe hydronic systems).

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 on the side of the fan coil, as this is what
allows the earth connection of the entire system.
