Swap McDonnell MIller 47-2 with VXT 120
I want to remove my McDonnell Miller 47-2 and change it to a VXT water feeder.
There are two wires attached to the #2 switch on the 47, Do I simply wire the VXT into that?
I have a model PS 800 low water cutoff already hooked up so the manual feeder is redundant with the switch.
The feeder is old and not working right so I want to change to a vxt..
Anybody who knows?

the two wires from the 47-2 were just part of the switch that cut power to boiler when water was low. I suggest just splicing those two together.
Next, if the PS800 cutoff is already wired, run a line and neutral from PS800 to vxt line and neutral. Then you need a wire from the W of the PS800 to the vxt feed.
Of course I recommend a good boiler guy do this or electrician, but if you are gonna do it yourself,
http://www.hydrolevel.com/pages/pdf_files/vxt_120.pdf has the perfect wiring diagram for the old PS800 and new (page 2)
If the boiler is large enough or
your area requires it, you may need 2 LWCO's on your boiler. Is the PS8000 an automatic or manual reset model?
Cost is what you spend , value is what you get.
