If the flow rate is too low, you need to fix this before moving on. Remove
any air, clean the filter in the unit and if it’s still not enough you need bigger
pumps. To clear the fault code, switch off both heating and hot water then
switch them on again.

3.
Select DHW ok
4.
All temperatures are listed.
On LT units the water storage temperature is lower (50°C) than a normal
cylinder. It’s important to check that any shower or bath mixers do not further
reduce the water temperature. Using your thermometer check that the hot
water comes out the tap at the same temperature it leaves the cylinder. If it
doesn’t you might need to make adjustments to taps mixers etc. DON’T raise
the cylinder temperature to compensate.
