Munchkin High Efficiency Heater w/ 925 Controller - Question - Heat not turning on

in Domestic Hot Water
Hello all, my heater is not kicking on, I turned it on from the thermostat a couple hours ago and we have baseboard heaters throughout the house, none of them are getting warm over the past couple hours.

I too a look at the display and it had a 71 on it when I looked at it an hour ago, it dropped to a 70 then now a 69, not sure what significance that has , as I couldn't find anything on line.

Any suggestions on what to test or reset?

Thanks all

    Can you show the thermostat? Does it have batteries?

    The control panel is showing the water temperature in the boiler. 
    It might be on “warm weather shutdown”. If it’s above 68F outside, it won’t fire. 
    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 the boiler start-up when you adjusted the temp at the thermostat?

    Why don't you just go into the programing and look at the data setup? You do have the installation manual, right?

    I think he is gone. Probably something simple he found. It would be nice to know, as we sit here with the engine idling.
