I think i know the answer based upon some previous threads, but figured I would ask. I have a Vectra M1 running in return mode, tried adding a battery backup yesterday. When I test it the pump turns off (water movement) however the lights on the controller remain on. Actually, the knob starts to blink and the power indicator shows a single light on the far right. I have heard the vectra needs a booster, anyone else get this working yet?
