Let's run the numbers. To heat 4.5gpm at 55F to 105F requires 1,874 btu/min. or 33 kW. So right at the start we can see you are short 6 kW of power power. If you put a 6 kW preheater before the Eco27 you can raise the incoming water temperature by 9F to 64F. The Eco27 would then be able to...

I would use neon lamp indicator like this one from DigiKey and wire it to L1 and L2.
