In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have read many good posts about the Alpha pump. I had a job with 2 zone valves and an Indirect. The boiler is a cast iron 40K. I used 2 Taco Sentry zone valves, Alpha pump and a separate pump with IFC.
I must say the first experience with the Alpha was less than positive. I felt the wiring was a bit tough as I have big hands. After getting through that turned on the boiler. All the lights came on on the pump once the zone valve opened. Went into the default auto adapt. About 30 seconds later I got 2 dashes on the pump display. Read manual check for flow, voltage locked rotor. Recycle power.
Re-purged and the same thing. The display says 1 watt and 0 gallons.
After trying different things I put one of the old Taco 007's in place of the Alpha. Did not even re-purge and all took off and heated.
Not real impressed with the first one.
