5.4.8 Hot Water Does Not Reach Temperature
POSSIBLE CAUSES SOLUTION
DHW ow too high. Adjust the inlet assembly, insert a ow restrictor.
Temperature setting for water circuit too low. Adjust the hot water circuit, depending on the desired temperature and
system conguration. See Table of Programmable Parameters in DC/HC
Controller Manual.
Water temperatures are set incorrectly Target water temperature is set higher than the maximum water
temperature.
No heat transfer as a result of lime scale or
fouling in the heat exchanger DHW side.
Descale or ush the exchanger DHW side.
Cold water temperature <5°C.
