It is a special device that controls the power delivery of the heating element, modulating it starting at 20% of output until 100% by acting on the rotation of the knob. In order to ensure safety for people, the device has an important element, which is a useful NTC sensor that prevents the ambient temperature from exceeding 37 ° C, in compliance with European legislation. It can be assembled with different heating elements, and its parts are easily obtained from our major European manufacturers and replaced. It is possible to select three preset schedules as indicated in the guide for activating the operating times:

1. Boost2h control: 2 hours of continuous heating at 100% capacity.
2. T24h control of the boost2h, to set it to happen automatically every day at the same time (2h on, 22hoff) (typically for morning shower).
3. T12h control of the boost2h, to set it to start automatically every 12 hours (2h on, 10h off, 2h on, 10hoff (typically morning and evening shower).
