I'm replacing my old boiler with a Wiel-McClain CGa-3, spark ignition
model. The boiler came with a Taco 007-f5 circulator. I bought an
additional pump, same model, thinking I would control my two baseboard
loops with the pumps same as my old set up. Now I see that the new
boiler control board has only one thermostat input and one circulator
output. Can someone walk me though how to wire the thermostats and some
external relays to power the pumps and keep it integrated with the
I've attached pdf of control board.....or at least I tried to.
