@old_scientist Thank you so much for this info 🙏🏻  I'm still in the very early stages of getting to grips with it all.

The booster is set to Use and the delay time is 75 mins.  Overshoot is 0C.

I've decreased the time the tank heats on the schedule down to 60 mins and will see how that goes.  This time is below the delay time of 75 mins for the booster anyway, so the booster even while on shouldn't affect anything.  As the overshoot is set to 0C that can't be responsible for heating the water higher than the set point.

I agree, it doesn't look like that was the culprit, but was worth checking.

Let us know how you get on.

My temp sensor is housed in a small (10mm maybe) dia pocket in the tank. At one time my DHW temp was way too high and I noticed the sensor had become dislodged (so was not reading actual temp. Replacing it brought them temp back to where it shound be and adding a small blob of hot glue has stopped a reoccurrence.

@lenny I think some owners even apply a blob of heat sink compound to ensure good heat conduction to the sensor. Toodles.

Could it be that the legionella cycle has been on and you've just noticed it once the temperature has come down a bit but it's still higher than your set temperature?

What temp have you set for your heating water? could there be an issue with the 3 way valve / zone valve?

FWIW I think you are doing the right thing putting the DHW onto timed as it's better for COP to heat the tank from a cooler temp rather than continuously on a 5 deg hysteresis.
