Control wiring

When converting a boiler from a tankless water coil to a indirect water heater, is there any modification needed to be made to a L8124A relay before adding a three zone SR503 switching relay. Not using a cold start

    Nope!

    The 503 style relay, regardless of who makes it, will align to the L8124 and you'll get great operation if everything is wired right and set correctly, FACT!
