TT Pres.Excell. 110 Second circ. wiring???
Hi all; I've installed the above gas boiler but am stuck at wiring the zone valves and 2nd circ. I have 3 AutoMag zone valves wired parallel back to 7 & 8 and fed parallel from 24v Honeywell AT72D Transformer (the book calls for R8285D). Also have a Grundfos circ. piped as second circ. but there is no place to connect my 2nd circ with 120v off the transformer I have so... could I just add a relay like the R8285D?
*I'm trying to use what materials I had from my old oil boiler.
*I am piped Primary/Secondary like Fig. 10 page 19 of TT manual.
Thanks in advance for any help...Billy

I just added a Taco SR501 Relay to my Honeywell Trans. and Automags. Tomorrow will be the test after the gas line is done. Thanks anyway, Billy
