Outdoor Time Switch, 24-Hour Single-Pole Double-Throw

I'm trying to wire this unit to my potlights.

Right now there is red, black, white and green wires. Red goes to one breaker and black goes to another breaker (each breaker is 15A).

How can I stick this into the mix?

On the unit there are 8 connects

They are labeled like this:

TIME1 TIME2 NC NO COM NC2 NO2 COM2

Thanks a lot!
