Combi boiler water temperature setting

[dullfogy]

Hello,

I just install a new vaillant ecoTec pro 30 Combi boiler few month ago, and I just realised that water temperature is keep go over the temperature I have set. e.g. I set the water temperature at 45 degree but it going up to 60 or even higher when I turn on hot water. Please can any one give me some advice, is this normal because this is first time I using Combi boiler, before I was using conventional boiler. Thank you.

If you're worried about the temperature shown on the display it's normal. The display shows the temperature of the water leaving the main heat exchanger, not the water temperature at the tap.
