4.7 Information from the display
The large-scale, four-digit, LED display allows numbers and letters to be indicated. Its size and clarity mean that it can
be read easily even when the light is poor.
Key Function
T1
Allows the steam cylinder to be manually drained. Pressing T1 once
causes the drainage valve to open. The red LED flashes. Pressing it again
causes the valve to close. If you forget to close the valve, it closes
automatically after 30 minutes.
T2
Works on double units only. Pressing T2 allows you to read or set the
operating data of either the left- or right-hand steam cylinder (the red
LED indicates which one).
T3
Allows you to select and show 3 operating variables: steam output
[kg/h]; current [A]; setpoint steam [%]. When T3 is pressed, the relevant
LED indicates which variable is being shown on the display.

Allows you to select:
• humidifier capacity limitation in %
• access to the programming level

On pressing T4 for the first time, the capacity limitation LED lights up.
The limitation value appears in the display and can be set, using the
SELECT button, between 20 and 100% (factory setting is 100%). When
another key is pressed, the last limitation value is automatically saved.
2. Activating the programming level.
