In ECO mode: I
If the ECO mode is set to I, when the boiler is used with an
external hot water tank, the water is not heated. If the hot water
tank is empty, the tap water will therefore be cold.

In Auto mode
If the setting is on Auto and the control unit is fitted with a ECO
function, the appliance adapts to the control unit setting.
For example: The ECO setting is tripped at night during reduced
temperature operation.
