If you have much more than two screws on a switch it"s more than likely a 3 way. The other choice would it is in a 120v/240v switch or something favor that for a motor pack possibly. If you have actually a black screw where the red cable is tied to on every switch, it"s a 3 way. Your are more than likely both 3 ways. They would certainly not run if they weren"t. Anyway right here are a few variations on exactly how to wire the up:

great and also easy to follow!

Forgot to cite the timer has to be a 3 way timer together well. From the pdf you connected it didn"t look favor it was unless I to let go something. I understand a most those room both solitary or 3 way depending on just how you desire to use it.
