Valiant echo tech plus 624 system boiler controlled by honeywell
rad symbol always on, is this normal ?
and also internal pump comes on and off automatically on its own is this normal ?
this happens when both HW & CH are both off in honeywell central heating
and HW & CH works as expected when we switch them on
Its constant running of boiler insp9ite of all controllers are off is bit worrying
