How do I/can I use a Taco sr503-exp-4 with an L8148j aquastat? Can I wire XX to TT TV on the aquastat? I want to control a primary pump and two additional circulators on the secondary piping.

Can I leave the primary circulator on aquastat's c c and have it energized whenever a sr503 turns on if I didn't use sr503 primary pump ON setting. In other words primary circulator wired to aquastat in parallel to secondary circulator wired to the taco switching relay?0

Yes. XX on the SR504 to TT on the aquastat. Any zone that energizes on the 503 will close XX, initiating a call to the aquastat and powering B1 and C1.
My setup is similar, but not millivolt.0
