askoheat plus base modes

Description of the Base Modes:

Fast heat

The heating element operates at full power to heat the water as quickly as possible. This setting is particularly useful, e. g. when combined with Time-of-Use tariffs during periods of low electricity prices.

PV surplus

In this mode, the PV system’s excess production—which would otherwise be subject to grid feed-in—is used for heating.

No heating

The heating element is inactive.
