Low water cut off - Electric boiler?

[slackdaddy1]

Finalizing my system with an Elctro mini boiler - EMB-S-5
I have heard mention of adding a low water cut off to electric boiler systems.
Reading through the Electro industries install manual, I see no mention of using a low water cut off. Is that something that is built into modern electric boilers?

i just asked that on your other post

Ayuh,.... insteada startin' tons of threads,...

Put it All in 1 thread, so the info in the other thread can be referenced,....
The Other thread,..

Ya got a closed system, 'n there should be a pressure switch,....
If the system is low on water, the pressure will be to low to fire,....

Why do ya have 2 fill points,..??
Ya should have a single fill point, with an Auto-fill valve, 'n check-valve,...
Which is usually "T"'ed at the expansion tank/ air strainer,...

I only started two threads,
One asking for an overall review of my system before I sweat it together.
And this thread asking a very specific question.
I put this as a separate thread (subject) on purpose, so it could be referenced at a later date by anyone asking the same question about low water cut offs with electric boilers.

As the electric boiler manufacture makes no mention in their manual (but they have endless pages of warnings and design criteria)< I guess I could put the low water cut off in series with the low voltage T-Stat.
