. A qualified engineer can modify this
value.

004
is set on
ENA
.
Note
When parameter
202
is set to
Off
, the anode warning
Ano
will not be shown on the
display. Also when there is a problem with the anode protection, this warning will not be
shown. The tank protection cannot be guaranteed. The warranty will be void.
10.3 Hysteresis
The water heater does not start immediately when the water temperature is below the
temperature setpoint. To prevent that the water heater switches on and off too often,
there is a margin; the hysteresis.
The standard hysteresis is 10 °C. Thus, the water heater starts to heat up when the water
temperature is 10 °C below the temperature setpoint. Use parameter
003
to change the
hysteresis.
