I just fitted a Monsoon Positve 4.0 bars twin pump. The pump starts when outlets are on but doesn't stop. I checked for leaks no leaks. I checked with a magnet if the reed clamps stars yes it does.I checked the wiring (for closed circuit) of the flow switch reed, it seems ok as per diagrams. So what next I have no idea what could be problem. What does PCB stands for? inthe trouble shooting guide they are talking about PCB in the terminal box?
