• 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 E5AZ/E5EZ exceeds the upper- or lower-limit value, the
upper or lower limit set value becomes the output level.
• MV upper limit
The setting ranges during standard control and heating/control output 2
control are different.
The manipulated variable at the cooling side during heating/cooling con-
trol is expressed as a negative value.
Control Method
Standard
Heating/cooling
• MV lower limit
The setting ranges during standard control and heating/cooling control
are different.
The manipulated variable at the control output 2 side during heating/cool-
ing control is expressed as a negative value.
