Solution
The circuit valve requires a certain time to open and
therefore to make the hot or cold water circulate inside Wait 2 or 3 minutes to allow the circuit valve to open.
the device.
The ventilation is delayed with respect to the new
temperature or function settings.
The device does not activate the ventilation.
Cold or hot water is missing from the system.
The hydraulic valve stays closed.
Make sure the boiler or the water cooler are on.
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 on, the problem may be in the
electronic control.
The ventilation does not start even if the water circuit is
filled with hot or cold water.
Check the motor windings and check if the fan rotates
freely.
The ventilation motor is jammed or burnt.
The wirings are not correct.
Check the electrical connections.
Leaks at the hydraulic connections of the system.
Losses in the valve group.
Check the leak and tighten the connection.
Check the condition of the gaskets.
The device is losing water in heating mode.
There is dew on the front panel.
Check the correct positioning of the thermal and acous-
tic insulations paying particular attention to the front
one located on top of the finned coil.
Detached thermal insulation.
As soon as the level of relative humidity drops, the phe-
nomena disappears. However, a few water drops falling
inside the device will not cause any malfunction.
High humidity conditions (>60%) might generate con-
densation, especially at minimum ventilation speeds.
There are water drops on the air vent.
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 device is loosing water in cooling mode.
The connection pipes and the valves unit are not well
insulated.
Check the pipe insulation.
Verify
The fan touches the structure.
The unbalancing generates excessive machine vibra-
tions: replace the fan.
The device generates excessive noise.
The fan is unbalanced.
Check the filters for dirt and clean them if necessary
