DESCRIPTION
The LS-3C is a low voltage wall switch used with a LightSaver
LCO-203 daylighting controller. It allows occupants to temporaily
override automatic ON/OFF daylighting control provided by the
multizone controller.
OPERATION
The LS-3C has two operating buttons (Automatic and On/Off). An LED
indicates whether the controller is operating the lights automatically or
is being manually overridden. Pressing the On/Off button temporarily
puts the controller into manual mode and switches the lights ON
or OFF. Pressing the Auto button switches the controller back into
automatic operation.
When the controller is connected to an occupancy sensor, the manual
override terminates when occupancy ends. When occupancy resumes,
the controller reverts to automatic control.
INSTALLATION
The switch is made up of two primary parts: the
cover plate and the back containing the buttons,
electrical components, wire terminals and mounting
strap. It mounts to a standard single-gang box.
Removing the Screwless Cover Plate
1. Press the black tab at the bottom edge of
the cover plate.
2. Pull the lower edge of the cover plate away
from the back.
3. Lift the cover plate up and off as shown in
Figure 1.
