Hot Water Does Not Reach Temperature - IBC DC Series Installation And Operating Instructions Manual

5.4.8 Hot Water Does Not Reach Temperature

POSSIBLE CAUSES
DHW flow too high.
Temperature setting for water circuit too low.
Water temperatures are set incorrectly
No heat transfer as a result of lime scale or
fouling in the heat exchanger DHW side.
Cold water temperature <5°C.
5-10
DC SERIES BOILERS / WATER HEATERS DC 15-95, DC 15-96, DC 20-125, DC 33-160
SOLUTION
Adjust the inlet assembly, insert a flow restrictor.
Adjust the hot water circuit, depending on the desired temperature and
system configuration. See Table of Programmable Parameters in DC/HC
Controller Manual.
Target water temperature is set higher than the maximum water
temperature.
Descale or flush the exchanger DHW side.
