DESCRIPTION AND OPERATION
The RT-100 is a time switch that turns OFF the connected light or fan (load) when
the selected time expires. While the switch is OFF the pilot light behind the ON/
OFF button illuminates and “OFF” appears in the display. When the switch is ON,
the display shows the amount of time the load will remain ON.
For times up to 59 minutes and 59 seconds, the display shows a blinking colon
between the minutes and seconds while the seconds count down continuously.
For times between 1 hour and 12 hours, the display shows a blinking colon
between the hours and minutes and the minutes portion of the display changes
only once a minute. See Fig. 1.
The RT-100’s lighted alpha-numeric
display is also used for programming
functions. With the programming
functions, you can decide:
• Delay — the amount of time the switch
remains ON with the initial press of the
ON/OFF button.
• Sound — whether the switch beeps for
each button press and every 5 seconds
for 1 minute before it turns OFF.
• Flash — if the lights ash to warn you
that they are going to turn OFF. When
Delay is set for 10 minutes or more,
lights ash once at 5 minutes and once
at 1 minute before turning OFF. When
Delay is set for 5 minutes or less, lights
ash once 1 minute before turning off.
Manual ON
When you press the ON/OFF button, it activates the Delay timer. If you want to
keep the switch ON for a time different from what is programmed, simply press
and hold the ON/OFF button until the display shows the desired time. When you
let go of the button the switch turns ON.
Manual OFF
While the switch is ON and the timer is running, press the ON/OFF button to turn
OFF the connected load without delay.
Changing the amount of time: At any time, you can press and hold the ON/OFF
button for 1 second to restart the timer. It goes immediately to the programmed
Delay time; if you need a different amount of time, keep holding the button for
at least 2 seconds. Hold the button until the display shows the desired time.
Releasing the button starts the timer countdown.

The time-out period can be set for 5 minutes
to 12 hours. The time is displayed in two dif-
ferent ways. For a countdown of less than an
hour, the display shows minutes:seconds. The
seconds count down continuously. If the count-
down is more than an hour, the display shows
hours:minutes, the colon flashes every second
and the display changes every minute.

WARNING
Disconnect power to the wall switch
box by turning OFF the circuit breaker or removing
the fuse for the circuit before installing the RT-100,
replacing lamps, or doing any electrical work.
INSTALLATION & WIRING
1.Prepare the switch box.
After the power is turned off at the circuit breaker
box, remove the existing wall plate and mounting
screws. Pull the old switch out from the wall box.
2.Identify the type of circuit.
In a Single Pole Circuit (see Fig. 2), two single
wires connect to two screws on the existing switch.
A ground wire may also be present and connected
to a ground terminal on the old switch. A neutral
wire should also be present in the wall box.
CAUTION
For your safety: Connecting a proper ground to the time switch provides
protection against electrical shock in the event of certain fault conditions.
If a proper ground is not available, consult with a qualified
electrician before continuing installation.
Only connect the RT-100 to a Single Pole Circuit. The RT-100 is not suitable
for 3-way switching. If the existing wiring does not match the description for a
Single Pole Circuit, you should consult with a qualied electrician.
3.Prepare the Wires.
Tag the wires currently connected to the existing switch,
so that they can be identied later. Disconnect the wires.
Make sure the insulation is stripped off the wires to
expose their copper cores to the length indicated by the
“Strip Gage,” in Fig. 3 (approximately 1/2 inch).

4.Wire the time switch.
Twist the existing wires
together with the
wire leads on the
time switch as
indicated in the
drawing. Cap them
securely using the
wire nuts provided.
See Fig 4.
• Connect the green
or non-insulated
(copper) GROUND
wire from the circuit
to the GROUND
terminal on the
RT-100.
• Connect the power
wire from the circuit
(HOT) to the black
wire on the RT-100.
• Connect the power
wire to the lamp or
fan (LOAD) to the red
wire on the RT-100.
• Connect the NEUTRAL wires
from the circuit to the white wire on the RT-100.
5.Put the RT-100 in the wall box with the display positioned above the
ON/OFF button.
Secure it to the wall box with the screws provided.
6.Restore power to the circuit.
Turn ON the breaker or replace the fuse.
7.Make any necessary programming changes.
See the Programming section for information.
8.Install cover plates.
Install industry standard decorator wall switch cover plate (not included).

PROGRAMMING
To program the time switch, you must access the programming buttons that are
located under the ON/OFF button. The wall switch cover plate must be removed
to gain access to the programming buttons.
1. Firmly grasp the side edges of the Lock Bar
and gently pull it away from the switch face
until it clicks. Do NOT attempt to pull the
Lock Bar off of the switch!

slides down approximately 1/2 inch to expose
the multi-function programming buttons.
The buttons are labeled from right to left:
Menu/Raisep: provides access to the
program items and shows their current
settings. With the rst press it shows
Delay time, second shows Sound setting,
third shows Flash setting. After an item
is Selected, the Raise button can increase
the setting or change it from O to On. For
the Delay setting, when you reach 1200 (12
hours), pressing Raise brings the display
around to 5:00 (5 minutes).
Select/Save: press this while a program item is displaying to change the
setting for the item. When the correct setting is in the display, press this again
to Save the setting for that item.
Lowerq: After an item is Selected, the Lower button can reduce the setting
or change it from On to O. For the Delay setting, when you reach 5:00 (5
