There is not enough information to answer this question.
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
Red is the alternate hot leg in a 2 way switch circuit
Connect the black wire to the incoming hot wire and the red wire to the out going load.
Remove the light sensor and place a switch between the red and black wires. The black wire is one leg of the "hot" pair and the load is connected to the red wire. This will now switch the black hot through the red wire that goes to the load.
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC

the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.

Nothing.
Connect the black wire to the incoming hot wire and the red wire to the out going load.
Red
Remove the light sensor and place a switch between the red and black wires. The black wire is one leg of the "hot" pair and the load is connected to the red wire. This will now switch the black hot through the red wire that goes to the load.
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC
Red is hot Green is ground White is neutral
It sounds like your switch is a three way switch. The wire that is on the different colour screw of the three screws will either be the "hot" wire or the wire to the load. The neutral might or might not be in the box that the switch is in depending on which end of the three way system you are at. See discuss question button below.No wires connected to a switch are neutral. A switch breaks the circuit of the hot wire. Black AND red are hot wires. White is used for neutral and is almost never connected to a switch.
The large red wire is the battery or hot wire.
The 1964 VW Beetle ignition switch only has three wires. Connect the red wire to the positive post. Connect the black wire to the negative posts. Connect the white wire to the auxiliary post.
