The keyboard features 4 page-navigation and value-editing keys, which have the following
functions:
- UP and DOWN: During editing, it modifies parameters; otherwise, it moves the cursor. If
pressed down and held for about 2 seconds during the display of the main page, the UP key
enables the display of the other probes.
-
SET / ENTER: During editing, it confirms the value; otherwise, it sends any commands
associated to the text where the cursor is positioned. If pressed down and held for about 2

- L4 = Compressor LED: This identifies the status of compressors. If it is lit, at least one
compressor is on; if it flashes slowly, at least one compressor is in alarm condition; if it
