n. description
1 button for accessing the most frequent operating parameters (codes Px, dx); also acts as an alarm relay reset button
(if the alarm is no longer active)
2 displays the unit of measure of the value shown on the display; pressed for 2 seconds accesses the display/
programming of the set point; if pressed together with button 1 for 5 seconds, accesses the routine for programming
the configuration parameters
3 when pressed, displays the value measured by the main probe (in ON/OFF control, nothing is displayed); in
programming mode increases the value or moves to the previous parameter
4 when pressed, displays the value measured by the compensation probe (only if featured); in programming mode
decreases the value or moves to the following parameter

7 LED representing that the value indicated on the display should be multiplied by one thousand
8 LED indicating the activation of the dehumidification relays
9 Flashing LED indicating the activation of the alarm relay
10 LED indicating steam production in progress; if flashing, indicates that production is lower than required

7.3 The humidifier controller
The following type of electric controller is available for the immersed electrode humidifier:
• Type H, with numeric LED display, on/off, proportional or probe-controlled operation.
This type of controller allows the complete control of steam production, including the possibility of activating the dehumidi-
fication function (H configuration); it accepts signals from room probes or external electronic regulators with proportional
or ON/OFF operation.
H controller, with numeric display LED, humidity control operation
