EASY 1 to 4 SP
PIDG.
Number of PID
groups
STD 1 to 4 CTL
Note1: The PID number (1 to 4, or R) is displayed on Group display while the parameter HYS,
HYSc, or DB is displayed.
Note
When changing the setpoint of the parameter PIDG., if the setpoint of the parameter PIDN
which belongs to the SP menu is larger than that of the parameter PIDG., the PIDN setpoint is
changed to the PIDG. setpoint.
