I have a Honeywell ct300 thermostat- and 1 pipe steam system. Do I set The thermostat as "Gravity air / water" or "Hot Water"?

    I have a Honeywell ct3400 thermostat- and 1 pipe steam system. Do I set The thermostat as "Gravity air / water" or "Hot Water"?

    If your system uses circulators, it is not a gravity system.

    Edit: I am sorry, I didn't notice you had a steam system. But then, why are you choosing between two "water" options? That's what misled me. Isn't there a "steam" setting?

    thermostat setting

    I'm not familiar with circulators- how would I know I my system had one?

    Gravity setting

    Remopve the thermostat from the subbase, find the screws labeled 1A & 1B, turn each one of these screws out one full turn.

    Here's a link to a pdf fill of the manual for the CT3400. Refer to page 18 & 19 for more instructions/pictures.

    Mr. Kalia

    Please reread his post, he did say he had one pipe steam.

    Don't worry about it Ray,

    If you have steam you don't have circulators.

    Thanks

    I just wanted to be sure 1 pipe steam was considered a gravity system

    Thanks again
