Function check F CHCK:<br />
Some countries only offer subsidies for the installation of solar thermal systems if the control<br />
units have a function check to detect a sensor defect and a lack of circulation. In the<br />
menu command F CHCK, the mechanic can activate this function check for the ESR21. This<br />
function check is disabled ex works.<br />
ON/OFF<br />
FC OFF: The function check is not active.<br />
FC ON: The function check is active. Monitoring makes most sense in solar thermal systems.<br />
The following system statuses and sensors are monitored:<br />
� An interruption or short circuit of sensors 1 or 2.<br />
� Circulation problems - an error message is issued if the output is active and the differential<br />
temperature between collector S1 and tank S2 is greater than 60K for more than 30<br />
minutes.<br />
The error messages are entered in the menu Stat. If Stat is blinking, a malfunction or special<br />
system status has been detected (see “The status display Stat”).<br />
