i bought a programable thermostat that says it needs a c wire to be able to use the remote...i dont have one of these wires on my old thermastat but im kinda understanding the c wire was just to power a clock on certan thermostats is there a way to rig a c wire to power what i need???
The C is the 24 volt common. You will need an extra wire in the bundle from the stat to the furnace. You should have a C terminal in the furnace on the terminal strip. Look on the circuit board on the furnace low voltage board. If you have the extra wire, hook it up on both ends.

the c wire is the common wire on your 24 volt control circuit.... wire used by some thermostats to power clocks or lights...... if you have extra wires in your thermostat wire cable it should be a blue wire and will hook up in your furnace to the blue wire or will be hooked to the c terminal on your thermostat wire connection board in your air handler...you can use any color wire in the cable that you are not using as long as you connect it up the way i just mentioned..
