I recently posted a request for help to wire a Woods 59018 digital timer switch, which I learned was not a three way switch but could be used an override-ON. Unfortunately the directions I followed for the override ON option did not work, maybe because the switch is defective. So I got a multi-mode Honeywell RPLS530A, which has only three wires and comes with a jumper cable. Again, I'm hoping someone can complete the attached diagram, telling me which wires to connect.enter image description here

  • What do the installation instructions included with the device say? There should be a section for connecting to a 3-way circuit. – Tester101 Jan 17 '16 at 15:00

    This is probably an easy wiring problem, but you must explain how you want the switches to behave. Do you want the front porch light switch to override the timer and force the lights on? Override the timer and force the lights off? Reverse the action of the timer? Play Big Ben chimes? What. – A. I. Breveleri Jan 17 '16 at 16:50

You should follow the instructions included with the device.

enter image description here

Connect wire "C" of the RPLS530A/RPLS531A to the "common" wire, identified when removing the old switch. Connect the other two RPLS530A/RPLS531A wires to the two remaining wires.

At the other 3-way switch, connect the jumper wire between the "common" screw and the screw where wire "1" of the RPLS530A/RPLS531A is connected.

So your diagram will look like this...

enter image description here

Wire it this way if you want the front porch light switch to override the timer and force the lights on: override-on

For full 3-way functionality:

  • Turn off the circuit, of course
  • Wire the incoming black wire to the C terminal on the timer
  • Wire the outgoing black wire to the 1 terminal on the timer
  • Wire the outgoing red wire to the 2 terminal on the timer
  • Jumper the two black wires in the switch box together

To answer A.I. Breveleri's question, I wanted the switch to turn the five lights in the chandelier on my front porch anti-clockwise in a strobe effect if a politician knocked on my door, gently turn on when I can home late at night and play jingle bells at Christmas. Maybe I'm asking too much. LOL!

Seriously, the wiring in my house is nothing like that shown in Honeywell's diagram. I followed the steps posted by ThreePhaseEeL and everything works perfectly: I can program the timer, turn the light on inside and off outside and vice versa...a true three-way operation.

Thank you all soooooo much for your valuable help and patience.
