Tekmar 256...
I'm wiring in a tekmar 256... I am all set w/ 1 exception. where does the wire on terminal 7 go to on a taco sr 502? Boiler is a Biasi and just has a 4006 operating control. ty,kpc
end switch
7 has to make to 9 on the tekmar. Run wires from these terminals to the ens switch on the Sr.
