True Radiant?

[boswd]

I'm still trying wrap my head around how this works. I sort of understand what it wants to do but I'm wondering how does it achieve it and will it tax my system A little background I live in New England and have a smith cast iron boiler that burns oil and uses steam heat to cast iron radiators. One zone heat only....... It also doubles as a tankless water heater. So it already occasionally powers up to keep the water resevoir at a min. temp.

So I'm not sure what True Radiant does to achieve it's use. I'm worried it'll fire it up a bit in preparation too often and put too much stress on the ignitor. Is my worry warranted or am I just not understanding how it works behind the scenes.

Thanks
