[. . . ] Troubleshooting Guide Observed Problem Switch timer does not switch ON/OFF but display looks normal. Switch timer won't enter AUTO or RANDom mode when you press MODE. Possible Cause Switch timer is not set in AUTO, RANDom, or MANual mode. The time of day or timer settings have not been set. Switch timer is in RANDom mode, which varies switching times up to ±20 minutes (to give your home a "lived-in" look). [. . . ] NOTE: The RED wire is not used in single-switch installations. Cap with a twist connector. NOTE: For new construction or to replace a dimmer switch, a lighted switch, or a 3-way switch without screw terminals, a single-pole switch can be used at the remote location, as shown. NOTE: If the building's wiring colors don't allow you to tell wire "A" from "B, " just pick one of the two wires and connect as if it is wire "B. " After the installation is complete, if the controlled light or device will not turn on properly, simply reverse wires "A" and "B. " See Steps J and K for how to check. Tuck wires into the timer wall box leaving room for the timer. Using screws provided, mount the switch timer into the wall box, then install the wall plate. Install the remote 3-way switch in its box and install wall plate. Turn the power back on at the service panel. Make sure the switch timer displays "MAN" mode. Do the following test with the remote switch in each of its 2 positions: Press the ON/OFF button on the switch timer several times. Each time that you push the ON/OFF button, the switch timer should "click" and the controlled light or device (the "load") should turn on or off. - If the timer clicks but the load does not operate, re-check your wiring and make sure the load is functional. If the timer clicks but the load only operates when the remote switch is in one of its 2 positions, you need to turn off the power at the service panel, then reverse wires "A" and "B. " You can reverse wires "A" and "B" at the remote switch wall box, or you can reverse wires "A" and "B" where they connect to the red and blue wires of the switch timer. Then turn power back on at the service panel and repeat Step J. Verify that the controlled load turns on or off each time that the remote switch is operated.
