11. READING AND PROGRAMMING THE PARAMETERS OF THE TYPE H
OR T CONTROL MODULE
The numerical, configuration and control panel parameters are grouped into three levels:
1. LEVEL 1 - Set Point, that is the value of the appliance's main setting St, accessible directly via the keypad for both
reading and modification.
2. LEVEL 2 - regulation parameters and measurements, that is the physical vales measured and the functional parameters
involving the regulation of the humidification process; these too can be accessed directly via the keypad for reading and
modification.
3. LEVEL 3 - configuration parameters consisting of the data needed to customise the control, according to the
requirements of the humidifier. These parameters are can be accessed only by password, to prevent the unwanted
modification of the configuration and thus the humidifier's essential functions.
Each parameter is composed as follows:

11.1 Reading and programming the Set Point
To read and/or change the Set Point, proceed as follows:
press the SEL button for around 2 seconds, until St appears;
on releasing the button, the unit of measure of the Set Point is displayed for 1
second, and finally the current set value;
to change the Set Point, press the
is being performed on the display;
press the SEL or PRG button to confirm the value displayed and conclude the
programming of the Set Point.
The characteristics and the range of variation of the Set Point are listed in Table 11.1.1.

measurements
The regulation parameters represent the values relating to the process of ambient humidity (or temperature) control and are
identified by a code ranging between P0 and P9, according to the criteria described in Table 11.2.1.
The readings are on the other hand the physical values measured by the transducers connected to the control, depending on the
model and the setting of the humidifier, and the number of operating hours from the previous reset; the measurements are
identified by a code ranging between d1 and d9 (see Tab. 11.2.2).
