3.1 Troubleshooting
In the event of a water leak or malfunction
immediately cut off the power supply and close
the system valves to the unit.
• the fan does not activate even if there is hot or cold
water in the hydraulic circuit.
• the appliance leaks water during the heating function.
• the appliance leaks water only during the cooling
function.
• the appliance makes an excessive noise.
• condensate forms on the front panel.
Should one of the following faults occur,
contact a qualified installer. DO NOT intervene
personally.
Faults and Troubleshooting
3.2 Fault-finding guide
These operations must be carried out by a qualified installer or by a specialised service centre.
EFFECT
CAUSE
SOLUTION
A delayed fan start up following set
temperature change or change of function.
The unit valves need time to open and as
a result the hot or cold water takes time to
circulate in the appliance.
Wait for 2 or 3 minutes for the unit valves
to open.
The fan does not function
No hot or cold water in the system.
Check that the boiler or chiller are
functioning correctly.
The fan does not activate even if there is
hot or cold water in the hydraulic circuit.
The hydraulic valve remains closed
Remove the valve actuator
and check if water circulation is restored.
Check the valve actuator by powering
it from a separate 230V (120V Canada/
US) source. If it activates then check the
electronic control.
The fan motor is blocked or burnt out.
Replace motor.
The micro-switch that stops the fan when
the filter grille is opened does not close
correctly.
Check correct fitting of grille and that the
micro-switch contact is activated.
The electrical connections are not correct.
Check the electrical connections.
The appliance leaks water during the
heating function.
Leaks in the hydraulic connections of the
system.
Check the leak and fully tighten the
connections.
Leaks in the valve unit.
Check the condition of the gaskets.
Condensation forms on the front panel.
Front panel insulation damaged or
detached.
Check the correct positioning of the
thermo-acoustic insulation, paying attention
to insulation in the front above the heat
exchanger.
There are drops of water on the air outlet
grille.
In situations of high humidity (>60%)
condensation could form, especially at the
minimum fan speeds
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.
The appliance leaks water only during the
cooling function.
The condensate tray is blocked.
Slowly pour a bottle of water into the low
part of the heat exchanger to check the
drainage; if necessary, clean the tray and/
or increase the inclination of the drainage
pipe.
The condensation discharge does not need
an inclination for correct drainage.
The connection pipes and the valve unit are
not insulated well.
Check the insulation of the pipes.
The appliance makes a strange noise.
The fan fouling adjacent parts.
Check if the filters are clogged and clean if
necessary
The fan is unbalanced.
An unbalanced fan can cause excessive
vibrations in the unit; replace the fan.
Check if the filters are clogged and clean
them if necessary.
Clean the filters.
