I am a welder and currently install commercial residential/industrial boilers for a living. I am generally familiar with the wiring and such- but I am NOT an electrician.
On to my issue:
adding a 4 zone relay (Taco sr504) to control DHW pump and future hot water heat zones to my existing steam boiler.
The isolated end switch terminals that are to connect to "T T" on the boiler- are they rated for 24 vac only or will that relay take line voltage ok?
