Note
The function control „flow and return in-
terchanged“ according to the VDI guidelines
2169 can only correctly detect and indicate
the error „0031 !FL/RE INTERCHANGED!”
if the collector sensor measures the tempera-
ture directly in the fluid at the collector outlet.
If the collector sensor is not correctly placed,
a false message may occur.
Î
Place the collector sensor directly in the
fluid at the collector outlet or deactivate
the “flow and return interchanged” func-
tion control.
