I have year old Worcester Greenstar 42CDi boiler.
This morning the display alternated between the temperature and showing this symbol –II- when I requested the rads to come on for the first time in a week.
It seemed to do this for around 10 minutes before the boiler kicked in properly and the temperature increased.
Can’t see this occurrence mentioned in the manual.
