10.5 Resetting Factory Values (Default Values)
The factory default can be reset only when the unit is turned on in the following way:
• within 5 seconds of turning on the unit (the three dashes will appear on the display) press the PRG
button and keep it depressed for about 5 seconds until the upper dash will appear and blink, as
indicated above;
• release the PRG button within 3 seconds; all factory-set parameters will be restored. As a confirmation,
the display will show the symbols above for 2 seconds;
• the operation is not carried out if you keep the PRG button pressed for more than 3 seconds after the
upper dash appears
The reset of the factory default values does not affect the selection of the unit of measure (parameter
A1); therefore it is advisable to check and memorize the unit of measure and then proceed with the reset of the
default values. In this mode the default values will be automatically converted to the units of measure selected.
10.6 Resetting the Hour-Counter
To reset the hour-counter (parameter d4) proceed as follows:
• press the PRG button for 5 seconds until the P0 code is displayed, and then press the S or T keys
until the parameter d4 is displayed
• press the SEL button until the value of the hour counter is displayed (preceded by 1 second by the unit
of measure)
• press simultaneously the S and T keys until the value is reset to zero, preceded by a brief flash
• press the PRG button to exit the procedure
10.7 Displaying and Modifying the Unit of Measure
The unit of measure displayed depends on the type of control and programming of the humidifier. The display
of the unit of measure can help avoid misinterpretations of physical values. In the case of non-dimensional
values the unit of measure is not displayed. It is possible to use the English units of measure (parameter A1).
The units of measure can be seen in the two right digits of the display:
