Question about Intermatic Hardware & Accessories
Cannot get the timer switch to function in 3-way (2 switch), could get the two switchs to get the light on but not run the timer. Am completely lost.
When installing a digital timer switch into a 3-way lighting circuit, you typically have to install a jumper wire across the "travelers" on the 3-way switch at the other end of the circuit, in order to get the timer to function.
If you have an Intermatic brand timer, the jumper is included with the timer switch, usually it will be a small, about 2-3 inches long wire with fork terminals on each end.
You should have the power turned off before installing the jumper. Also, there is a distance limit (75-80 feet of wiring) as to how far apart the two (2) switches can be from one another, in order for the timer to work (with the installed jumper).
Normally, the travelers are one the same side of a 3-way switch, but you can use a voltage detector to confirm which wires are which (prior to turning off the power) to make installing the jumper easier. If you contact the manufacturer of your particular timer, they can email you a owners guide/installation pamphlet that shows the proper installation procedures for your timer switch.
If you have an Intermatic product, you can use the link below to contact them for the needed info.
Hope you find this Very Helpful and best regards!
