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 control thermostat is performed via the control of the
solar system. In the control of the solar system there can be set two parameters, namely
the switch-on temperature and the switch-off of the control thermostat. Both
temperatures can be set between 0 and 95 ° C. See manual of the solar control (Res-
control) to set these two temperatures.
