Freshness control

The freshness control exchanges the water in the pipe during longer disuse. This avoids stale water.

Temperature starting barrier

The temperature starting barrier prevents the circulation pump from switching on as long as the pipe at the temperature sensor – caused by constant taking of warm water (even after the restarting barrier time) – still contains 35°C/95°F warm water. Typical situations: Someone fills water into a bath tub or several persons in a multi-family house take water at the same time.

Restarting barrier

The restarting barrier prevents the circulation pump from switching on again within the next minute, because within this period enough warm water is still in the pipe.
