in Gas Heating

I have a V2532FFUC-US and a MCC (commercial) controller. I need 160F outlet temp used in

base-board heating. Current unit, ~12 yrs old, has some faults the tech cannot figure out.

Setpoint does not hold, reverts to 140 after 15-20 minutes. Is there drop-in replacement? (no piping changes).

    why a boiler given that Rinnai publishes LOTS of stuff promoting Series I "solo" as built

    for home heating via hot water??

    i series is a Rinnai boiler. The solo Ex I 120s or a Ip120S is a heating boiler only an indirect would needed to be piped for DHW.

    The I series combi, such as a i120cn or a ip090199c, well that does heating and also DHW in one unit,

    Your tankless water heater, you mention above was designed for just heating domestic water, if you must you can use it for central heating but it needs to be piped open loop for warranty

    It would seem that only 2 things could wrong with the current system, the controller or the board, I wonder if the board is not recognizing the mcc controller.
