Error handling

The controller's response to errors in the measuring circuit depends on the setting
made on operating line 126 (d.h.w. storage tank sensor/thermostat).
In the event of a short-circuit or an interruption of one of the 2 measuring circuits,
the controller continues to operate with the other measuring circuit, if possible. An
error message is not delivered.
If both measuring circuits do not produce a valid measured value, an error mes-
sage is delivered. D.h.w. is no longer heated; the charging pump will be deactivat-
ed.
In the event of a short-circuit or an interruption of one of the 2 measuring circuits,
the controller continues to operate with the other measuring circuit. An error mes-
sage is delivered.
If both measuring circuits do not produce a valid measured value, 2 error messag-
es are delivered. D.h.w. is no longer heated; the charging pump will be deactivated.
If there is neither an interruption (thermostat open) nor a short-circuit (thermostat
closed) in measuring circuit B31, an error message is delivered. D.h.w. is no longer
heated; the charging pump will be deactivated.
If there is neither an interruption (thermostat open) nor a short-circuit (thermostat
closed) in one of the measuring circuits, an error message is delivered. The con-
troller continues to operate with the correctly working measuring circuit.
If there is neither an interruption (thermostat open) nor a short-circuit (thermostat
closed) in both measuring circuits, 2 error messages are delivered. D.h.w. is no
longer heated; the charging pump will be deactivated.
In the event of a short-circuit or an interruption of one of the 2 measuring circuits,
the controller continues to operate with the other measuring circuit, if possible. An
error message is not delivered.
If both measuring circuits do not produce a valid measured value, an error mes-
sage is delivered. D.h.w. is no longer heated; the charging pump and the collector
pump will be deactivated.
In the event of a short-circuit or an interruption of one of the 2 measuring circuits,
the controller continues to operate with the other measuring circuit. An error mes-
sage is delivered.
If both measuring circuits do not produce a valid measured value, 2 error messag-
es are delivered. D.h.w. is no longer heated; the charging pump and the collector
pump will be deactivated.
If a measured value of the d.h.w. temperature is not available and the temperature
is queried, the QAW70 room unit displays ---.
