FAILURE OF THE THERMOSTAT FUSES AND REPLACEMENT
The installation and the electri-
cal connections of the units and their
accessories must only be carried out
by people possessing the technical/
professional requisites for system
installation, transformation, extension
and maintenance, and who are able to
check these aspects for the purposes of
safety and correct operation. They will
be generically referred to in this manu-
al as "Personnel with specific technical
skills". Check that the power supply is
disconnected before carrying out any
procedures on the unit.
If the fuses are burnt and for possible
replacement:
• Remove the delivery frame
• Extract the thermostat card
• Open the thermostat box
• Replace the faulty fuses
The fuses are 5 x 20 T series
(delayed) from 2 A to 10 A
•
WARNING: for correct replacement,
the 2 A fuse must be inserted in loca-
tion F3, while the 10 A fuse must be
inserted in F2, as shown in the image
below.
Before installing the electric box, the
configuration of the electronic board
dip-switches needs to be checked in
order to adjust the board to the system.
Connect the VMF-E4 control panel,
supervision network cable, TTL
network cable, and probe and valve
cables based on system requirements.
For the connections, refer to the
wiring diagrams of the fan coil and
