The light situayed at the bottom of the display show the state of the various relays as set out below:
STATE INDICATION LAMPS
*1) For more details see Operative Diagrams.
*2) o.ALA = 0 : Minimum and maximum alarm sets user settable (see ALARM keys).
*3) If o.ALA = 1 : Minimum or maximum absolute alarm set value.
If o.ALA = 2 : Minimum or maximum relative alarm set value.
For more details see Operative Diagrams.
*4) :=1 : °C Temperature range.
=2 : °F Temperature range.
*5) You can correct the readings on the various sensor (+ or -).
