Parametrisation
When the tap support is activated (during commissioning or in the menu „Circulation“), a calibra-
tion process is started after the commissioning. To ensure the correct operation, calibration is
also scheduled to start on every Sunday at 3:00 AM.
During commissioning, the calibration must not be interrupted.
If the weekly calibration process is not successful after 10 minutes, the process is cancelled
and the controller uses the former calibration values.
Calibration
During the callibration process a text is shown that the flow rate is measured and no tapping
is allowed.
After confirmation the circulation pump is switched off and the controller is waiting until the flow
rate has dropped to 0 L/min. Afterwards only the circulation pump is switched on and after another
60 seconds the flow rate is measured. The display shows a “Please wait” sign.
After another minute, the flow rate is measured again, and the two flow rates are compared.
If the results are identical (+- 1L/min), the result is saved.
If not, the process is started over until either the results match or 10 minutes have passed and
the calibration is cancelled and the former values are used.
