    They Say

    "Manages 2 separate reset curves for high and low temperature zones". I would say your radiant classifies as a low temperature zone. I haven't been able to pull up the I &O manual online. I'd contact the manufacturer and get it before making up your mind. Knowledge is power.

    Lambda Pro

    The way I understand it, you tell the unit what type of gas you are using, and it monitors and optimizes based on that. I'm asking about the possibility of a catastrophic failure, leading to the unit attempting to adjust itself to the wrong gas.What safeties are there to prevent that?

    I've had boilers run for months where the contractor forgot to go into the coding and tell the boiler he was using LP. If combustion ran outside the paramters it would lock out the burner. fault code would lead you to a combistion problem.

    TT reset curves

    Just got the installation manual and user manual  from TT and it does have two reset curves for both a high temp and low temp HC plus DHW priority.  The trimax control looks fairly straight forward and i guess there are 6 preset curves in there to meet most applications.
