10.2 System monitoring

If an error occurs, the

symbol will always flash.

10.2.1 Sensor monitoring

The sensors required for the control

functions and their connection cables are

monitored for breakage and short circuit. If

a defective sensor is recognised by the

software, the

symbol is displayed.

The source of the error can be found by

scrolling.

Important:

The use of incorrect temperature

sensors can therefore also lead to one of

the error messages.

10.2.2 Flow monitoring

Display Meaning

No circulation in solar circuit

In the case of the controller SDC 306, the temperature difference between the collector and the

storage cylinder is checked. If this exceeds the amount of (60K + Td start), this is interpreted

as an error because such large differences should not arise given normal system dimensions

and assuming that the pump is switched on.

In the case of the SDC 306 control unit, the flow quantity is checked when the pump is

switched on. If, for a period of approx. 30 minutes, no flow is detected, this is interpreted as an

error.

The error message is automatically reset once the fault has been removed.

10.2.3 System protection function

The system protection function switches the

system off if the “maximum collector

temperature” is exceeded. As soon as the

temperature drops 15K below this value, the

system is started up again.

Display

Meaning

Short circuit of temperature sensor for current measuring point

Break to temperature sensor of current measuring point, circulation

error if energy yield estimation is activated
