3.4.4 Domestic hot water eco and preheat modes
• Eco mode is an energy saving feature which disables the Preheat function:
– Eco is enabled by default, during the initial appliance start up and Eco is displayed.
– During the ON periods set by the time control, the appliance will heat the cylinder If the temperature is approximately 10 °C
below the set temperature.
• Preheat mode, the appliance heats the cylinder more frequently. This tops up the cylinder temperature for quicker heat up
times, this is useful for large/longer demand periods during the hot water ON periods.
– During the ON periods set by the time control, the appliance will heat the cylinder if the temperature is approximately 5 °C
below the set temperature.
