Slide the control panel into its housing in the upper part
of the device and fix it with the two fixing screws (ref. A).
To install the board:
-
connect the grounding cable to the unit structure (ref.
M) using the fixing screws (the minimum force that
must be applied for tightening screws must be around
2N);
-
connect the fast connector of the MOTOR to the other
on the board (ref. I) *;
N.B.:
should the board not be fitted in the factory, the
fan motor must be rotated 180° due to the length of
the standard fan coil cable.
-
on the two GRID block terminals (ref. L) there is a
bridge that allows SLI and RSI versions to work without
a microswitch.
-
For other versions, remove the bridge and connect the
two terminals originating on the grill safety microswitch;
N.B.: s
hould the two brown terminals on the unit be
too short, replace them with those included in the kit
packaging.
-
connect the water probe connector H2 (ref. F) on the
unit.
The water temperature probe controls the temperature
inside the batteries and determines when the fan
starts according to pre-set parameters (minimum
operation in winter and maximum in summer). Check
that they are correctly inserted into the compartment
on the battery.
-
make the electrical connections, tidy the cabling;
-
refit the vanity plate on the side of the unit;
-
tighten the upper screws on the control panel;
-
place the screw head covers in their housing on the
control panel;
-

For versions with hydraulic connections on the
right, refer to the relevant paragraph
The on-board controller with speed selector and ON/OFF
key, room thermostat adjustable from 5 to 40°C, winter
summer selector and minimum winter temperature function
(30°C) and maximum summer temperature (20°C) is suitable
for fitting on board the unit and has a 230V - 1A output for
controlling a solenoid valve.
