System Messages
All system messages are displayed with a blinking caution symbol.
In case of sensor errors the sensor in question is also marked with short circuit or interruption symbols.
Interruption
Displayed sensor or line connection interrupted
/ defunct.
●
Check the resistance value of the sensor and
compare to the resistance table.
●
Check all contact points up to the sensor.
Short circuit
There is a short circuit of the sensor on the
display, the line or the sensor input on the
controller.
dT too high
A fixed value of 20 K is added to the
temperature difference between collector (T1)
and tank sensor (T2). The message is displayed
if after 30 minutes the total temperature
difference has not been reduced.
●
Check pump/pump connections/wiring.
●
Check system for air, and vent if required.
●
