Adjustment Level Section 5-4
• This parameter sets the rate of change during SP ramp operation. Set the
maximum permissible change width per unit of time as the SP ramp set
value. The SP ramp function is disabled if this parameter is set to OFF.
• During temperature input, the decimal point position of the SP ramp set
value is dependent on the currently selected sensor, and during analog
input it is dependent on scaling.

SP ramp time unit (advanced function setting level): Page 201
• 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
The setting ranges during standard control and heating/cooling control
are different.
• MV Lower Limit
The setting ranges during standard control and heating/cooling control
are different. The manipulated variable for the cooling control output side
during heating/cooling control is expressed as a negative value.
