AERMEC VMF-E1X Manuel D'utilisation Et D'installation page 19

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.
• 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 electric cables of the
secondary water temperature probe
(SW1) (in 4-pipe hydronic systems).
• Connect the cables for the external
contact (if envisaged).
• Connect the cables for the presence
sensor (if envisaged).
• Connect the cables for the microswitch
(if envisaged).
• Connect the mains and RS485 power
supply cables (if connected to the
mains).
• 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 on the side of the fan coil, as this is what
allows the earth connection of the entire system.
