• Smart Mode: This intelligent mode monitors your hot water usage patterns over a 7-day cycle. It anticipates your needs and preheats water accordingly, ensuring hot water is available when required while minimizing energy consumption during periods of low demand. If no hot water is needed, the unit maintains a minimum temperature.

The water heater is equipped with two anodes to protect the tanks from corrosion. These anodes should be inspected and replaced periodically by a qualified technician, typically every 1-2 years, depending on water quality.

5.3 Frost Protection

The unit includes a frost protection function. If the ambient temperature drops too low, the water heater will automatically activate to prevent the water from freezing, protecting the unit from damage.
