My Greenstar Ri boiler works well generally but it behaves oddly in two ways.
When it is just heating the DHW it goes into over-temperature shut-down when the demand stops. This is okay because the boiler cannot modulate low enough so the water is almost bound to go over-temperature. However the manual says that the boiler should be able to come on after a three minute delay. But it doesn't - it comes on much later when the water inside the boiler has had time to cool down I suspect.
The other odd behaviour occurs when the demand for DWH stops whilst the demand for CH continues. The boiler turns off for a few seconds and then starts up again.
Has anyone else experienced these odd behaviours?
