Advanced Function Setting Level Section 5-6
• 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.
• 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.

“PID ON/OFF” (initial setting level)
“ST” (initial setting level)
MV upper limit
The control must be 2-PID control,
and the “ST” parameter must be set
to “OFF”.

Control Method Setting Range Unit Default
Standard MV lower limit +0.1 to 105.0 % 105.0
Heating/cooling 0.0 to 105.0 % 105.0
Control Method Setting Range Unit Default
Standard −5.0 to MV upper limit −0.1 % −5.0
Heating/cooling −105.0 to 0.0 % −105.0
