Safety First!
The HYDRA solar water heating system contains built-in maximum electrical protection with an IEC standard-compliant safety system (RCD).
Temperature is controlled by a digital sensor and a thermal safety switch.
- Internal 30 mA RCD (Residual Current Device, Differential)
- RCD cuts off power in less than 15 milliseconds in case of fault
- Automatic daily RCD self-test
- Thermal cutoff switch (Bi-Metallic Switch, 80°C)
- Internal electronics are isolated
