Heating/cooling output
If C26 (heat/cool control ) is set to 1 (use (individual PID)), the heating and cooling
MVs shown in the figures below are output in accordance with the setting for
“Heat/cool control dead zone.”

The figure below shows the relationship between the MV low limit, MV high limit,
cooling MV low limit, and cooling MV high limit.
MV low limit ≤ heating MV ≤ MV high limit
Cooling MV low limit ≤ cooling MV ≤ cooling MV high limit
