Series Boilers only)
POSSIBLE CAUSES
SOLUTION
DHW flow to high.
Adjust the inlet assembly, insert a flow restriction.
Temperature setting for water circuit too low.
Adjust the hot water circuit, depending on the desired temperature and
system configuration. See 2.3.4 Table of Programmable Parameters
No heat transfer as a result of lime scale or
fouling in the heat exchanger DHW side.
Descale or flush the exchanger DHW side.
Cold water temperature <5°C.
