INSTALLATION AND WIRING
Step 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.
Step 2 Identify the type of circuit.
In a Single Pole Circuit (see Fig. 1), 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.
NOTE: Only connect the RT-20 to a Single Pole Circuit.
The RT-20 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 qualified electrician.
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.

DESCRIPTION AND OPERATION
The RT-20 is a time switch that turns
OFF
the connected light or fan when the selected time expires. An indicator light illuminates when
the switch is
OFF
. When selecting a time delay of 10 min or more, as time expires, the button LED’s will move through the next available
time delay, always giving an indication of the amount of time left before the time delay expires. One minute before each time delay
transition, the active button LED will flash, providing the user an indication of the transition.
Manual ON
Turn
ON
the connected light or fan by pressing the desired time button, or the
ON/OFF
button. If you press the
ON/OFF
button, it
activates the timer that was last used.
Manual OFF
While a timer is active, you can press the
ON/OFF
button to turn
OFF
the connected light or fan without delay.
Changing the Selected Time
If you decide that you need more or less time than you originally selected, restart the time switch by pressing the button that matches the
amount of time you think you’ll need.
