ol-h
MV Upper Limit The control must be set to 2-PID control.
The ST parameter must be set to OFF.
A Position-proportional Model must be set to close
control.
ol-l
MV Lower Limit
• The MV Upper Limit and MV Lower Limit parameters set the upper and lower limits of the
manipulated variable. When the calculated manipulated variable exceeds the upper or
lower limit value, the upper or lower limit value will be the output level.
• MV Upper Limit
• MV Lower Limit
The MV for the cooling control output during heating/cooling control is expressed as a
negative value.
