with respect to the new temperature
or function settings.
- The circuit valve requires a
certain time for its opening and
therefore to make hot or cold
water circulate in the appliance.
- Wait 2 or 3 minutes so that the
circuit valve opens.
Ventilation speed increases or de-
creases automatically.
- The electronic control works so
as to adjust the best level of
comfort.

or select silent function in case
of need.

tilation.

the system.

ter refrigerator are operational.

there is hot or cold water in the hy-
draulic circuit.
- The hydraulic valve remains
closed.
- Dismount the valve body and
check if water circulation is
restored.

the valve by powering it sepa-
rately at 220 V. If it activates, the
problem may be in the electronic
control.

the free rotation of the fan.
