Indication of error in the LCD display
Short circuits and interruptions of each single temp. sensor are only indicated when the corresponding sensors are
y.
really in use on the basis of the selected funtion.
The controller automatically recognizes the below-described errors and indicates them after 10 sec on its LCD displa
Only after confirming by pressing a button does the controller start working regularly again. If a malfunction is not
eliminated despite indication and confirmed the LCD display indicates again error. When there are several errors the
one with the "lowest impact" (e. g. first T1, then T2 etc.) is indicated.
Note:
If the controller recognizes an error the output of the controller switches off due to safety reasons.

Significance
Short circuit T1
short circuit of sensor conductor T1 for the registration of the collector temperature
Interruption T1
Cut-off of sensor conductor T1 for the registration of the collector temperature
Short circuit T2
short circuit of sensor conductor T2 for the registration of the „storage tank temp. bottom“
Interruption T2
Cut-off of sensor conductor T2 for the registration of the „storage tank temp. bottom“
Short circuit T3
short circuit of sensor conductor T3 for the registration of the „storage tank temp. top“
Interruption T3
Cut-off of sensor conductor T3 for the registration of the „storage tank temp. top“
stt: No °C
temp. sensor T3 not existing (T3 is normally only needed for the indication of storing high
temp. and so exclusively necessary within the function heating system)
