Status display Stat<br />
The status display provides information in special system situations and problems. It is<br />
mostly intended for use with solar thermal systems, but can also be useful with other diagrams.<br />
The status display can then only operate if an active function check is set off via defective<br />
sensors S1 or S2. For solar applications, a distinction has to be made between three<br />
status areas:<br />
� Function check and collector excess temperature are not active = no system response is<br />
analysed. Only a bar appears in the display in Stat.<br />
� Collector excess temperature is active = the excess temperature that occurs during system<br />
standstill only leads to the display CETOFF (the collector’s excess-temperature cutoff<br />
is active) during this time under Stat.<br />
� Function check is active = monitoring of interruption (IR) and short circuit (SC) of the solar<br />
sensors and circulation problems. If this outlet is active and the differential temperature between<br />
collector S1 and tank S2 is greater than 60K for more than 30 minutes, the error<br />
message CIRERR (circulation error) is output. This status (Stat blinks) is maintained even<br />
after the error has been remedied and has to be cleared in the status menu using the<br />
command CLEAR.<br />
In Stat, OK is displayed when the monitoring function is activated and the system’s operation<br />
is correct. If there is anything unusual, Stat blinks regardless of the display position.<br />
