6.3.4 Alignment of the water meter
If the water volume must be corrected, the parameter TCON.WCNT must be adjusted. The measurement must be made at the operating point. Fluctuations occur with very small dosing volumes.


Note:
Do not use the water feed rate for the correction; work instead with the total sum counter (see SERV.VA from Version 26A onwards or Σ3).
This prevents temporary control deviations from leading to a miscalculation!


The following calculation can be used for the correction.

TCON.WCNTnew = nominal value ∗ TCON.WCNT Value _ measured

Example:
A water volume of 95 litres instead of 100 litres was measured. The new value can be calculated as follows:
TCON.WCNTnew = 100 ∗ 105.7 = 111.3
95
