6 Parameters
sprt
sprl
• These parameters set the rate of change during SP ramp operation. They set the
maximum permissible change width per unit of time as the SP ramp set value and the SP
ramp fall value. The SP ramp function is disabled if this parameter is set to OFF.
Function
• For a temperature input, the decimal point positions of the SP ramp set value and SP
ramp fall value depend on the currently selected sensor, and for an analog input they
depend on the Decimal Point parameter.

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.
Function
• MV Upper Limit
Setting
Standard
Heating/cooling control
• MV Lower Limit
The MV for the cooling control output during heating/cooling control is expressed as a
negative value.
