7-6-13 MV Upper Limit (ol-h)
MV Lower Limit (ol-l)
Condition: The control must be 2-PID control.
Function • The “MV upper limit” and “MV lower limit” parameters set the upper and
lower limits of the manipulated variable. When the manipulated variable
calculated by the E5ZN exceeds the upper or lower limit, the upper or
lower limit will be used as the output level.
•MV Upper Limit
The setting ranges during standard control and heating and control output
2 control are different.
The manipulated variable at the cooling side during heating and cooling
control is expressed as a negative value.
• MV Lower Limit
The setting ranges during standard control and heating and cooling con-
trol are different.
The manipulated variable at the cooling side during heating and cooling
control is expressed as a negative value.
• Setting changes to “MV upper and lower limit” must be enabled by exe-
cuting a software reset or by turning ON the power again.
