Hi
My boiler seems to working ok (HW & Heating), but when "No ext. call for heat", its starts pump a few times and then its start quick flashing red. However, when given ext. call for heat, after a while its going green and fire up as usual. Recently I've noticed that, when 'Temp. control set to Off' and No ext. call for heating, its flashing orange. As per manual it is "Ext. call for heat with Temp set to Off) which make no sense.
Recently PCB was replaced and tubing on the fan was cleaned.
Any advise?
