Question about Intermatic Inc. EJ500C Digital Wall Switch Timer - Self-Adjusting Feature
Have 2 3-way switches need to replace one with a EJ500C timmer
Locate the COMMON wire
connected to first old switch.
It might be attached to a different
colored screw, or find
markings on old switch.
Connect BLACK wire from
switch timer to COMMON
wire, using a twist connector.
Connect the other two wires from the old switch to either the
BLUE and RED wires from the switch timer.
Connect the ground wire from the box to the BARE COPPER
wire on the switch timer. If there is no ground wire, ground the
switch timer to the box. If the box is plastic, connect the bare
copper wire to ground as supplied or contact an electrician.
Locate the COMMON on the second old switch of the 3-way pair.
Connect jumper wire (supplied) from the COMMON terminal
to either of the other terminals on the remote 3-way switch.
Make sure all twist connectors are tight.
Tuck wires into wall boxes leaving room for the devices.
Mount the devices into the wall boxes, then install the wall plates.
Turn 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 NEXT ON/OFF button on the switch timer several
times. Each time that you push the NEXT ON/OFF button, the
switch controlled light or device (the “load”) should turn on
or off. If so, proceed to Section 3.
If the timer display changes between ON and OFF but the
load does not operate, re-check your wiring and make sure
the load is functional.
If the timer display changes
between ON and OFF 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, change the jumper
wire to the other terminal. Then turn power back on at the
service panel and repeat. good luck
