EFFECT
CAUSE
SOLUTION
The ventilation is delayed with
respect to the new temperature or
function settings.
The circuit valve requires a certain
time to open and therefore to make
the hot or cold water circulate inside
the device.
Wait 2 or 3 minutes to allow the
circuit valve to open.
The device does not activate the
ventilation.
Cold or hot water is missing from the
system.
Make sure the boiler or the water
cooler are on.
The ventilation does not start even if
the water circuit is filled with hot or
cold water.
The hydraulic valve stays closed
Demount the body of the valve and
check if the water circulation is
restored.
Check the valve operation feeding
it separately to 230 V. If you were
to turn, the problem may be in the
electronic control.
The ventilation motor is jammed or
burnt.
Check the motor windings and check
if the fan rotates freely.
The wirings are not correct,
Check all wirings.
The device is losing water in heating
mode.
Leaks at the hydraulic connections of
the system.
Check the leak and tighten the
connections.
Leaks at the valves unit.
Check the condition of the gaskets.
There is dew on the front panel.
Detaches thermal insulation.
Check the correct positioning of
the thermal and acoustic insula-
tions paying particular attention to
the front one located on top of the
finned coil.
There are water drops on the air vent.
High humidity conditions (>60%)
might generate condensation, espe-
cially at minimum ventilation speeds.
As soon as the level of relative
humidity drops, the phenomena
disappears. However, a few water drops
falling inside the device will not
cause any malfunction.
The device is losing water in cooling
mode.
The condensate tray is clogged.
Slowly pour a bottle of water in the
lower section of the battery to check
the drainage; if necessary clean the
tray and/or improve the slope of the
drain pipe.
The condensate discharge pipe does
not have the slope required for
correct drainage.
The connection pipes and the valves
unit are not well insulated,
Check the pipes insulation.
The device generates excessive noise.
The fan touches the structure.
Check if the filters are dirty and clean
them if necessary
The fan is unbalanced.
The unbalancing generates excessive
machine vibrations: replace the fan.
Check if the filters are dirty and clean
them if necessary
Clean the filters
