Piping and wiring Qs about the Peerless Purefire

Ron Jr._3

Anyone install these on a regular basis ? Have a few question on how to pipe and wire 2 radiant zones to existing pipework on this specific boiler . Already has an indirect and 3 baseboard zones .



Thanks in advance .

Same

as any other P/S setup. Are both radiant zones going to be the same temp?

Ron Jr._3

Same temp

for both radiant zones .



This was more a wiring question than piping . The internal control has the capacity to run a general pump ( for the boiler ) , a DHW pump and a CH pump ( for the heating zones ) . Since the radiant needs it's own pump , you can't control the CH pump normally anymore and you lose some advanced functions . I guess a RIB relay tied into a single zone relay for the radiant might work . Gotta think about that .......



Does the I series Taco zone valve work downstream of a pump ? Can it work on just water temp ? With a mix valve that can be piped after a circ you could do different temperature zones on one pump, theoretically  ..........................

I- valve

You have to pull through it
