Bradford White Indirect help

Rob_5

I have a Bradford White Indirect water heater that I'm tying into a Weil Mclain gas boiler. I'm using a Taco SR503 controller. The indirect will be Priority zone 1.

Are the leads coming out of the Bradord White to be conected to the "T.T." on the SR 503? The instructions show the leads to the Bradford White to be wired in parallell with a zone valve or a circ. at line voltage.

The SR503 T.T.in are just dry contacts. Will the indirect work without a voltage applied?

Thanks,

Rob

TT

IS not a dry contact. You have 24 at TT so that the control is the dry on the indirect.

Hope this helps. Remember a thermosate has ( T87F) has no power so how could it close the loop, it must get 24 from the control on TT.
