Output Adjustment Functions Section 4-17
Note When the manual MV limit is enabled, the manual MV will be re-
stricted by the MV limit.
• For heating/cooling control, upper and lower limits are set of overall heat-
ing/cooling control. (They cannot be set separately for heating/cooling.)
4-17-2 MV at Stop
The MV when control is stopped can be set.
When setting the MV when control is stopped, set the MV at Stop and Error
Addition parameter (advanced function setting level) to ON.
â– Standard Models
For heating/cooling control, the MV at stop will apply to the cooling side if the
MV is negative and to the heating side if the MV is positive. The default is 0.0,
so an MV will not be output for either standard or heating/cooling control.
â– Position-proportional Models
Open, close, or hold status can be selected for floating control or when the
Direct Setting of Position Proportional MV parameter is set to OFF. With open
status, only the open output will turn ON. With close status, only the close out-
put will turn ON. With hold status, the open and close outputs will both turn
OFF. The default setting is for hold status, with no outputs.
