Is the boiler stat the turnable knob at the front? If it is I have tried it in various positions ie half turn, 3/4 turn and turned fully.
Even when the hw is on and heating and room stat is off, the boiler still plays up. Does this mean the room wireless stat is not the problem? Therefore the problem is most likely pump or port valve.
