7.8 TABLE OF ANOMALIES AND REMEDIES
The interventions must be carried out by a qualified installer or by a specialised service centre.
Effect
The coil does not reach a uniform
temperature.
A delayed activation of the ventilation
respect to the new temperature or function
settings.
The ventilation speed increases or
decreases automatically.
The appliance does not activate the
ventilation.
The ventilation does not activate even if
there is hot or cold water in the hydraulic
circuit.
The appliance leaks water during the
heating function.
There are formations of dew on the front
panel.
There are drops of water on the air outlet
grill.
The appliance leaks water only during the
cooling function.
The appliance makes a strange noise.

7 - MAINTENANCE
Cause
Air present in the inner circuit of the
appliance.
The circuit valve needs some time to open
and as a result the hot or cold water takes
time to circulate in the appliance.
The electronic control adjusts the comfort
level regularly.
No hot or cold water in the system.
The hydraulic valve remains closed.
the fan motor is blocked or burnt out.
the micro-switch that stops the ventilation
when the filter grill is opened does not close
correctly.
the electrical connections are not correct.
Leaks in the hydraulic connections of the
system.
Leaks in the valve unit.
The thermostatic valve built into the
connection unit between plate and battery
does not close the flow towards the wall.
Thermal insulation unstuck.
In situations of high humidity (>60%)
condensation could form, especially at the
minimum ventilation speeds.
The condensation bowl is blocked.
The condensation discharge does not need
an inclination for correct drainage.
The connection pipes and the valve unit are
not insulated well.
The fan touches the structure.
The fan is unbalanced.
Dirty filters.
Remedy
Release the air several times
Wait for 2 or 3 minutes to open the circuit
valve.
Wait for the temperature adjustment or in
case of necessity select the silent function.
Check that the water boiler or cooler are
functioning correctly.
Dismount the valve body and check if the
water circulation is restored. Check the
working efficiency of the valve by powering
it separately with 230V. If it activates the
problem could be the electronic control.
Check the windings of the motor and the
free rotation of the fan.
Check that by closing the grill the
microswitch contact is activated.
Check the electrical connections.
Check the leak and fully tighten the
connections.
Check the state of the gaskets.
Replace the union that joins the
thermostatic valve to the water inlet upper
unit.
Check the correct positioning of the
thermo-acoustic insulation paying attention
to that in the front above the finned
battery.
As soon as the humidity starts falling the
phenomenon disappears. In any case the
presence of a few drops of water in the
appliance does not indicate a malfunction.
Slowly pour a bottle of water in the low
part of the battery to check the drainage; if
necessary, clean the bowl and/or increase
the inclination of the drainage pipe.
Check the insulation of the pipes.
Check for any interference by manually
rotating the fan.
The unbalancing causes excessive
vibrations of the machine; replace the fan.
Clean the filters
