PLS530A/PLS531A
PROGRAMMABLE WALL SWITCH
1. APPLICATIONS
The PLS530A/PLS531A switch can be used in a single-pole or 3-way installation with
the following types of lighting:
• Incandescent
• Halogen
• Low-voltage halogen with transformer
• Fluorescent
THE PLS530A/PLS531A SWITCH CANNOT BE USED WITH A LOAD BELOW 40 W,
A LOAD ABOVE 500 W OR A MOTOR.
2. INSTALLATION
1. Cut power at the circuit breaker to avoid electric shock.
2. Remove the existing switch. (For a 3-way installation, identify and label the
wire that is connected to the "common" screw.)
3. Install the new switch (refer to the appropriate section below).
4. Apply power at the circuit breaker.
NOTE:
The white wire is not the neutral wire but the wire going to the load.

3-wire cable
Connect wire "C" of the PLS530A/PLS531A to the "common" wire, identified when
removing the old switch. Connect the other two PLS530A/PLS531A wires to the two
remaining wires.
At the other 3-way switch, connect the jumper wire between the "common" screw and
the screw where wire "1" of the PLS530A/PLS531A is connected.
NEW 3-WAY INSTALLATION
120 VAC
The jumper wire is not required in this installation. A single-pole switch can be used as
the other switch in a 3-way installation.
3. POWER-ON
1. Pry the switch door open from the bottom
using a small screwdriver.
2. Ensure the ON/OFF selector is set to ON.
3. Reset the switch using a paper clip. 0:00
and MO will flash.
If the display is blank:
• Ensure the ON/OFF selector is properly
engaged in the ON position. Push it to the right
using a small screwdriver.
• If the programmable switch controls a lamp equipped with a built-in On/Off
switch, ensure the lamp switch is set to On.
• Ensure the light bulb is not burned out and is tightly screwed in its socket.
EXISTING 3-WAY INSTALLATION
If either switch does not work properly, rewire the jumper between the "common" screw
and the other screw.
WARNING: BEFORE REPLACING THE LIGHT BULB, PLACE THE ON/OFF SELEC-
TOR IN THE OFF POSITION. FAILURE TO DO SO MIGHT DAMAGE THE SWITCH.
4. SETTING THE CLOCK
NOTE:
The switch displays the time in 24-hour format by default or following a
reset.
1. To change to 12-hour format (or vice versa), proceed as follows:
a.
Press one of the control buttons to ensure the MAN or AUTO indicator is
displayed.
b. Press the MIN and HOUR buttons simultaneously and briefly
(0:00 display = 24-hour, 12:00 display = 12-hour).
2. Set the time using the HOUR and MIN buttons. If you have selected the
12-hour format, ensure that PM appears on the screen when an afternoon time
is displayed.
