I set my master valve type to pump start relay. For the last 3 days, I have seen no alerts. Neither a zone alert about the master valve zone nor an alert about low pressure (probably because the pump turned on correctly). Hopefully, I won’t have to go to a lower amperage PSR, even though Munro said the model I had required 350 mA. I did get info on a replacement PSR or the parts required to modify my existing PSR. If I get zone faults again I might consider one of these options.
Thanks to everyone for their input.
