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


Could someone give a clear explination how the high and low limit settings work? Exactly when each one does its function and whats going on to activate them.

    Use the cold start boiler diagram

    No, just use the low voltage TT terminals on the aquastat to energize the boiler, as opposed to the ZC, ZR terminals.
