Connecting the control board.
This control board is a panel with 8 capacitive keys and the display shows
function AUTO ventilation adjustment step.
The thermostat is adjustable from 5 to 40 ° C, it has a summer and winter
selector through the water temperature probe (10 k) positioned in the cockpit
on the battery of the device. It can handle the functions from a minimum
water temperature (heating mode) of 30° C and a maximum water
temperature (cooling mode) of 20° C.
The control board is inside the machine and has two outputs at 230 V, one for
the management of a solenoid valve to control the water and another one to
manage the heating element of the front DUAL KHERR panel.
The PCB provides also the possibility of free operation without the water
sensor H2 in which case the stationary fan thresholds are ignored.
For access to inside of the machine and make the electrical connections follow
the following steps:
- Detach the suction grille (ref.
A
)
and remove the fixing screws
(ref.

and release the right side lifting it
upwards (ref.
D
);
- Remove the cover of the control
box (ref.

-next page) and
perform the connection (see
connections);
- Fix the probe to sense the
temperature of the resistance H4
