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 kΩ)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.
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) *;
- 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;

The regulator can also work without the water probe
