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?
