Turn off the water heater

Turn off for a short period

To turn off the water heater for less than 2 months, change parameter 001 to OFF, refer to
Set a parameter value (see section 4.1).
The water heater will switch to OFF mode (see section 3.2.1.1) and the frost protection is
on.

Note
If the water heater is in OFF mode for more than 2 months and no water is drained, air
bubbles may be formed in the water heater. This can lead to air in the water pipes.
