Hello
we have a c15 year old Valliant eco boiler. A few of our radiators were not working and the plumber turned the pump speed up to 100%. Unfortunately the boiler is now too noisy and I would like to turn it back to Auto or 85%. I navigated to menu d.15 but pressing - or + are not responding and I am unable to change to setting. Can someone kindly help me in how I am change the settings - I assume I need to press a button combination to enter update mode? Thank so much
