Would a Goldline GL-30 controller be an easy and appropriate replacement for
a 25 year old Rho Sigma 500s controller for an older Grumman Sunstream
system. Both seem to use 10k ohm/77 deg thermistors, so I could leave the
existing ones in place; they are OK. The Rho Sigma board is getting a bit
unreliable and I'm getting too old to go to Radio Shack for resistors, ect.
TIA

As long as you are wanting to control pump(s) at 120VAC, it should work just
fine.

 thanks for the advice. It will power one Grundfos pump, so no problem.
