Automatic calibration
The fill status is measured, via means of capacitance, by a sturdy PTFE Sensor cable. This is hung from the top of the tank. The setting of the respective tank water height (top and bottom) levels is done via digital calibration using two buttons on the main unit. The switching range for supplemental mains water supply by a magnetic valve is at approx. 2.5 % of the measuring range, so that the flow of mains water is only activated when required. The mains water inlet supply is time-monitored, so that any possible malfunction is prevented. A further automatic protection switch prevents the calcification of valves by regularly opening the valves, for a few seconds at a time, to clear any build-up.
