I'm almost done replacing the builder's switches throuhout the house with decora and i have added timers for the bathrooms's fan. One of them though, is a three way switch (the builder added a switch on the main floor to turn off or on the fan on the second floor).
I found a Leviton 3-way timer... but it has five wires and even after the reading the instructions twice I am not sure what wires to connect.
I have included two pictures to show the existing wall switch and new timer.
Can anyone help me with how to connect the different wires, please?
