5�2 Troubleshooting table
Eect 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
lled 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 on, 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 the electrical connections.
The device is losing water in heating mode. Leaks at the hydraulic connections of the system. Check the leak and tighten the connection.
Losses in the valve group. Check the condition of the gaskets.
There are water drops on the grid. High humidity conditions (>60%) might generate con-
densation, especially at minimum ventilation speeds.
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.
The device is loosing 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 pipe insulation.
The device generates excessive noise.
The fan touches the structure. Verify
The fan is unbalanced. The unbalancing generates excessive machine vibra-
tions: replace the fan.
Check the lters for dirt and clean them if necessary Clean lters
