I see in another post you seemingly can NOT use a non sqe pump in a grunfos 301 setup. Well... I have done so doing a new pump replacement and it DOES work. The first of the nine 301 fault indicator lights show working and all is working. However, the ninth connection to pump light (pump connection) is red. I really dont need to see the nice signaling lights moving upward to see the water moving on the front screen. And it does shut down (as in off no pressure on the 301 from time to time turn 301 off and on to fix) but other than that working. Does anyone know if that means... the pump itself is doing something it shouldn't like always on or some other anomaly? Its installed already DIY into existing system. Not really interested in removing pump again. Anyone else done this?? Greatly appreciated any advice (even if this is stupid to do ) Thanks!!
