I received an error message on my rinnai M090CN that reads
Time Program Error: Time Program service type mismatch. enter into technical menu and check it.
I am not an HVAC guy, I did however install the boiler. I am unable to figure out what this is stating.

    Couldn't find anything in their user manual. Sounds like a reminder to service the boiler.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    Did a solution get found for this? I have the same error and even factory reset won’t help

    From the home screen
     -press ok
    -scroll to complete menu-press ok
    -scroll to screen settings-press ok
    -scroll to time program service type-press ok
    -there are two options here-change it from whichever you’re initially set on. 
    -the boiler will restart and you’ll be all set
    -should it reappear, you’ll need to replace the board and/or the display. 

    -I’ve seen this on two separate installations and each time this procedure cured the issue
