Sysyem is a Navin 110 supplying two fin tube upstairs zones and one radiant basement zone in slab. Infloor utilizing mixing valve and boiler is using factory outdoor curve settings. 
Added Emerson E2 CX100 controller as a boiler monitor. It monitors space temp, outdoor air and boiler supply return water temps.
For your consideration the most recent graphs from this years startup. Overnight temps have been warm, boiler running under low load contions. Purple line is the return water temp and green is supply. You can see an excellent delta T when the infloor runs, but when its only 1 upstairs zone the return temps are higher. You can also see the boiler cycles and off cycles.What other information can I find with this data as it pertains to boiler performance?

    How much does your babysitter charge per hour? Do they take care of ages 3 thru 7? My usually babysitter can't do it Thursday night. She has a big Algebra exam on Friday and needs to study on Thursday.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Short cycling us not great for any boiler
    Does the boiler have settings to help lessen cycling? Ramp delay, step firing?
