LEGRAND Wattstopper TDR Instructions D'installation page 3

When a lamp must be replaced, use the Air Gap Isolation feature for safety. This feature is only available at the dimmer, which can be
identified by the light level LEDs on the left of the product, or the fan speed control, which can be identified by the 4 fan speed control
buttons. The air gap can not be activated from the Touch Remote.
After a power failure, all devices automatically return to the state they were in immediately prior to loss of power.
In a multilocation circuit with one or more multilocation remotes, the dimmer works, but the Touch remotes do
not function:
• This condition would exist if the LINE and LOAD connections are reversed. Check to make sure the connections are correctly
terminated at the dimmer.
• The Touch remotes require a ground connection. Check to make sure the ground wires are securely connected.
The light level changes without pressing any switches, or the dimmer does not respond when I press its switch.
• There may be a problem with the traveler wire. Remove power from the circuit. Disconnect all traveler wires from the dimmer's
remote terminals. Restore power. If the dimmer now operates the load properly, the problem is the traveler wire. It may be too long
or may be shorted to another conductor.
