    CH/DHW Systems

    I've been wiring a few S/Y Plans recently and there's one thing I can't for the life in me figure out. What is (or was?) the CH OFF terminal used for on some programmers? I know the DHW OFF terminal is used in a Y Plan setup but haven't seen any other methods that require the CH OFF terminal.
