On the smart control panel attatched to a boiler mate WH-7p I wired a hot wire to the black and a neutral to the white.DID THE SAME TO THE TACO SR504.I took the two orange wires and connected them to ''TT'' on zone 4 (which is the priority zone).From ''XX'' (end switch on taco sr504) I went to ''TT'' on the honeywell L7248 control for the boiler.From the sr504 zone 4 120v hot and neutral terminals for the ciculator I wired the 120v hot to the 120v hot on circ and neutral to the neutral on circ. Then I put the priority switch on the sr504 to the on position. Everything seems to be working but customers are complaining the domestic hotwater is not as hot as it used to be.Did I wire everything okay?

I have found my own solution. There was an option that I was not made aware of. There were 2 boiler controls to choose from.One was with an option for an indirect fired water heater and one was without.The company that sold me the boiler just assumed it was for heating(my bad).The new control comes with options zr and zc terminals.That is what you need for domestic hot water so that you can adjust the boiler not to go below 140 degrees F.This boiler was for my uncle not for profit(maybe to whomever reported abuse or not).
