6-6 PID Setting Level
6
These parameters set the PID constants for each PID set number. If auto-tuning is executed, these
parameters are set automatically.
These parameters set the output dead band width for heating/cooling control for each PID set number.
A negative setting sets an overlapping band.
*.c-p
PID * Proportional Band (Cooling)
The control must be set to heating/cooling control
and 2-PID control.
*.c-i
PID * Integral Time (Cooling)
*.c-d
PID * Derivative Time (Cooling)
(*: 1 to 8)
These parameters set the PID constants for cooling control.
These parameters are automatically set according to the Heating/Cooling Tuning Method
parameter when auto-tuning is executed.
* The unit is determined by the setting of the Integral/Derivative Time Unit parameter.
The Proportional Band (Cooling), Integral Time (Cooling), and Derivative Time (Cooling)
parameters are initialized if the Integral/Derivative Time Unit parameter is changed.

*.cdb
PID * Dead Band (*: 1 to 8)
The control method must be set to heating/cooling
control.
• These parameters set an area in which the control output is 0 centering around the set
point for a heating/cooling control.
