All modifications on the operating unit parameters must be carried out by qualified personnel.
Incorrect programming of the parameters may cause damage to the unit, and consequently the loss
of guarantee of the unit.
COD: The code which appears on the display
The field variation for the parameters,
MIN: Minimum value for the parameter.
MAX: Maximum value for the parameter.
UNIT: The units of measure used.
C=Centigrade, s= seconds, min=minutes, h=hours, Khrs=hoursx1000
VAR.: Minimum variation allowed.
DEF: The default value, factory set.
The table below gives the following information for each parameter.
The parameters
