I would like to add a Honeywell RPLS740B to a circuit with two three-way switches to control four outside lights. I realize the RPLS740B is not compatible with a three-way circuit, but my question is if it is possible to wire it such that three-way switching is "disabled" but the circuit still works with the timer? For example:
I have identified the switch on the line side, fed by a two-wire cable from the panel. Can I install the timer in place of this switch and tie the load side of the timer with both travelers leaving the box? It seems to me that the timer would then power both of the travelers and the outside lights would be on with the timer regardless of the position of the second (load-side) three-way switch. I would be OK with that compromise (i.e., loose three-way functionality from second switch).
Is it safe to tie the travelers together? This would obviate the need to cap any wires.
Is an alternative to cap the red traveler, install the timer in place of the first line-side three-way, and use the black wires throughout the circuit? This would leave the second load-side three way as a dummy?
Is there another option?
