CONNECTIONS TO THE BOARD

• The installation of the VMF-E19/E19I 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 connections
that were of the control board.
• Remove the cover of the thermostat hous-
ing.
•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.
• 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.

temperature probe (SW).

(if envisaged).
• Check all the connections and relative
cables are well fixed.

them being cut, crushed, jerked, scraped,
or generally damaged.

possesses the necessary features.

• Fix the power supply cables and valve
cables using the cable clamp.
