The PLS750C/PLS751C programmable wall switch has been designed to control lights and motors:
Lights and resistive loads
1800 W (15 A @ 120 V)
1440 W (12 A @ 120 V)
Cut power at the circuit breaker to avoid electric shock.
Remove the existing switch. (For a 3-way installation, identify and label the wire that is connected to
the "common" screw.)
Install the new switch (see the appropriate section below).
Apply power at the circuit breaker.
EXISTING 3-WAY INSTALLATION
Connect the LOAD wire on the PLS750C/PLS751C to the "common" wire, which you identified when
removing the old switch. Connect the NEUTRAL wire to the neutral (white) wires. Connect the LINE and 3-
WAY wires to the two remaining wires. At the other 3-way switch, connect the jumper wire between the
"common" screw and the screw where the LINE wire of the PLS750C/PLS751C is connected.
NOTE: If the timer screen does not turn on when you apply power at the circuit break (step 4), cut the power
at the circuit breaker again, switch the blue (LOAD) and the black (LINE) wires and reapply power.

5.1.3 Random Mode
In Random mode, the switch has no specific times to turn the lights on or off. This mode is
designed to give the impression the house is occupied during your absence. It is similar to the
Automatic mode except there is no fixed program. The programs are automatically set to different
times by the switch every day. The
The first "On" program occurs at sunset. Each "On" program lasts between 1 hour and 1
hour and 30 minutes; each "Off" program lasts between 15 and 30 minutes. The last "Off"
program occurs between 10:30 pm and midnight.
5.1.4 Temporary Override
When the switch is in Automatic or Random mode, you can press the main button at any time to override the
default state for the current program. The lights will turn off if they are on and vice versa. The icon (On or Off)
of the new state flashes to indicate that the state is temporary. The new state is maintained until you press
the main button again or till the next "On" or "Off" program.
The time display flashes on the screen when the time has not yet been set or after a 4-hour power outage.
Use the Time menu to select the time format (12-hour or 24-hour) and to set the clock and date.
NOTE: The date is used to determine the sunset and sunrise times.
