8.2.3 Fail-safe mode
The fail-safe mode becomes active as soon as one of the
listed errors occurs. In fail-safe mode, the actuator closes
the control valve to prevent uncontrolled potable water
heating. The fail-safe mode is active as long as an error is
present.
When the cause of the error has been corrected, most
error messages are automatically reset and the fail-safe
mode is deactivated. Only the actuator errors must be
reset manually by an error reset.
8.2.4 Error reset
If the rotary knob is set to the error reset index ((3) Fig. 44
