position two-level
control)
Heating-side
ON/OFF control
hysteresis (in
Heating/cooling
control)
EASY
In ON/OFF control or Two-position
two-level control: 0.0 to 100.0% of
PV input range span (EUS)
In Heating/cooling control or
Position proportional control: 0.0
to 100.0%
PID
HY.UP
Upper-side
hysteresis (in ON/
OFF control)
EASY
0.0 to 100.0% of PV input range
span (EUS)
HY.LO
Lower-side

OFF control)
EASY
PIDN

EASY 1 to 8 SP
PIDG.
Number of PID

STD
Set a number of PID groups to
use.
1 to 8
CTL
Note1: The PID number (1 to 8, or R) is displayed on Group display while the parameter HYS,
HY.UP or HY.LO is displayed.
Note2: In Cascade control, the LP2 lamp is lit while the Loop-2 parameter 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.
