4.3 Temperature pointer (items VP and VV)
With the temperature value pointer item VP several important calculation results can be selected which then can
be requested by the temperature pointer value item VV.
First load the pointer (item VP) with 2 digits (v, w), a separator which can be a ‘ . ’ (point) or a ‘ , ’ (comma), and
another 2 digits (x, y) according to the table below.
