If T3 is interrupted no message appears
SYS flashes in the controller display
Possible cause / remedy
SYS means there is a system error. This means that
despite the pump running, a temperature difference
exceeding 80 K between the collector and the stor-
age tank was recorded.
The following causes are possible:
The pump is faulty or not correctly connected
The isolating valve in the solar circuit is still closed
Air is in the solar circuit •
•
•
Since a standard circulation pump cannot eliminate
air bubbles inside the piping system, the heat transfer
medium circuit comes to a standstill.
Have professional personnel check the solar
energy system to prevent damage.
Once the fault has been remedied, press any but-
ton to acknowledge the fault message.
