The controls have two independent free contacts to control a chiller and a boiler and a presence input . The 2-pipe
versions have a 230 V output for powering the summer and winter solenoid valve while the 4-pipe versions have 2
independent 230V outputs to power a summer solenoid valve and a winter solenoid valve .
The water temperature probe (10 k
Ω
)located in the well on the battery manages the minimum in heating (30°C) and
maximum in cooling (20°C) functions .
The board can also operate without a water probe, case in which the fan stop thresholds will be ignored .
Mounting
Place the control panel into its housing in the upper
part of the machine and fix it with the two supplied
screws (ref . A) .
To install the connection box:
-
open the box (ref . B);
-
insert the lower lug into the special slot (ref . C) on the
side of the appliance;
-
hook the upper part of the box to the side (ref . D);
-
fix it with the two supplied screws (ref . E);
-
fix the earth wire to the cooler-convector (ref . M)
structure using the supplied screws (the minimum
force of about 2N must be used when screwing-up);
-
connect the rapid connector on the motor (MOTOR)
to that on the board (ref . I) *;
-
the 2 terminals of the GRID clamp (ref . L) feature a
jumper that ensures the operation of the
VN / VO /
VI
versions without microswitch .
-
For the other versions remove the jumper and
connect the two terminals from the grid safety
microswitch*;
-
connect the water probe to the H2 connector on
the machine .
The water temperature probe checks the temperature
inside the batteries and determines the start of the
fan based on the set parameters (minimum winter
and maximum summer functions) .** Check that it is
inserted correctly in the well on the battery .
-
Make the electrical connections, order the wiring
and fix the wires using the 3 supplied clamps (ref .
G);
-
close the box and fix with the 4 screws (ref . H);
-
mount the aesthetic side panel on the Cooler-
convector/cooler-radiator;
-
tighten the upper screw on the control panel;
-
place the screw cover into the slot on blind panel;
* For versions with hydraulic connections on the
right refer to the relevant paragraph
** The regulator can also work without the water
probe
