The water heater is under water pressure (up to 8 bar (= 800 kPa)). These is supplied as
much cold water as the is consumed hot water. The regulation thermostat automatically
switches the power supply. This means that if the water temperature drops below the set
temperature, the circuit is closed and the is supplied to the water. The circuit is opened
when the desired water temperature is reached.
Changing the temperature of the thermostat can be done by the control knob of the
thermostat that is positioned behind the cover with the elements. Remove the cover and
the thermostat will be visible.
Due to the limit of scale it is recommended that the temperature is set at 60°C. In
addition, a safety thermostat is built in, which switches, at a water temperature of 95°C,
the power supply to the elements.
