Hi,
I need to run a wire from the attic (where the A/C and heating units will be) to the location of the thermostat on the first floor. I don't know specifically what I'll have in the attic and what thermostat I'll have.
How many wires should I have in the wire to make sure I'm not short on that number in the future. Is six wires good enough for any heater+A/C combination?
Thanks!
