However, this system has a protection that prevents ice formation inside by activating the electropump when the
temperature falls to values close to freezing point. In this way the water inside is heated and freezing prevented.
The Anti-Freeze protection works only if the system is regularly fed: with the plug disconnected or in the
absence of current the protection cannot work.
However, it is advised not to leave the system full during long periods of inactivity: drain the system accurately
through the drainage cap and put it away in a sheltered place.

6.1.4 "BP1" Blockage due to fault of the delivery pressure sensor (system pressurisation)

If the device detects a fault in the delivery pressure sensor the pump remains blocked and the error signal "BP1" is given.
This status begins as soon as the problem is detected and ends automatically when correct conditions have been
restored.

6.1.5 "PB" Blockage due to supply voltage outside specifications

This occurs when the allowed line voltage at the supply terminal assumes values outside the specifications. It is reset
only automatically when the voltage at the terminal returns within the allowed values.

6.1.6 "SC" Blockage due to short circuit between the motor phases

The device is provided with protection against the direct short circuit which may occur between the motor phases. When
this blockage is indicated you can attempt to restore operation by simultaneously holding down the + and – keys, but this
will not have any effect until 10 seconds have passed since the moment the short circuit occurred.
6.2

Manual reset of error conditions

In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the + and – keys.
6.3

Self-reset of error conditions

For some malfunctions and blockage conditions, the system attempts automatic self-reset.
"BL" Blockage due to water lack
"PB" Blockage due to line voltage outside specifications
"OT" Blockage due to overheating of the power stages
"OC" Blockage due to motor overload
"BP" Blockage due to fault of the pressure sensor
For example, if the system is blocked due to water lack, the device automatically starts a test procedure to check
whether the machine is really left definitively and permanently dry. If during the sequence of operations an attempted
reset is successful (for example, the water comes back), the procedure is interrupted and normal operation is resumed.
Table 9 shows the sequences of the operations performed by the device for the different types of blockage.

7. RESET AND FACTORY SETTINGS

7.1

General system reset

To reset the system, hold down the 4 keys simultaneously for 2 sec. This operation is the same as disconnecting the
power, waiting for it to close down completely and supplying power again. The reset does not delete the settings saved
by the user.
