ok, few electical questions.

First I'll briefly explain what I'm trying to do.
Hooking up a thermostat for infloor heating in kitchen, existing house,
not new.
So we are installing a new Range to replace the stovetop that was there
from previous owner, we ran a new wire for the new range. We are now
using the existing wire (from stovetop) for the hookup of the infloor
heating witch is a 240v line which is required for the infloor heating.
Now the problem.

This a 3wire (red,black,white & ground). Now the thermostat requires 2
wires to hook up. my question, which wires do I hook up? I turned on the
breaker to see what voltage each wire has:

White 0 volts
Black 118 volts
Red 119 volts

do I just hook up the black and red wires and forget the white wire?

I know, call an electrician, but I almost got it done, this is my last
problem.

Any help would be appreciated.

Thanks,
Steve

The old cooktop used a neutral (white wire), the floor heat does not. You
should run the red and black feed wires (240 volt) to the "line" side of a
double pole thermostat, and run two conductors from the "load" side of the
thermostat to the heating unit(s). Install proper grounding as per
instructions
