How to calculate taco x pump settings

UPDATE: It seems it was a matter of changing temp settings and a possibly faulty outside temp sensor. For now, it's working fine at 0F° since I have changed the out dsgn temp.

Hi all,

I have radiant floor heating with a taco xpb1 pump. After much trouble as a first time homeowner in Alaska, i thought i had solved the problem with the heating not reaching setpoint when the temperature dropped. It was working fine but then we had yet another drop in temp (single digits F) and it's having trouble to reach setpoint again. I don't want to mess with the settings without having a reference of how high i should set up the water temperature. I'm also wondering if the system won't be able to heat up the place if we hit -30F. Anyway, is there a source to calculate the setting i should use in the taco xpb1? Last time I changed mix dsgn (145) and mix min (115) and that did the trick. I tried calling taco, but the agent said I needed to know which sensors I have installed to receive tech support (sadly I don't know because the previous owners didn't leave any instructions though im almost certain you can figure it out with their support).

    yes, the sensors and where they’re located dictates, either straight delta T, setpoint, or outdoor reset. You can go through your setting with Taco tech support and confirm your sensors are located properly for mode of operation you’re setting up.

    Hopefully this was helpful. Taco Texh support is 401-942-8000

    What's with the flexible, PVC looking intake piping? I hope the high temperature exhaust piping isn't the same kind of material. (Looks like it's covered by some sort of fabric). Also, are the two small sound dampening bats intended to muzzle the boiler sound?

    @Wellness no idea about the fabric thing. I guess the sound dampening was put there to dampen sound.
