DESCRIPTION AND OPERATION
The RT-24 is an astronomic time clock that controls the connected light or fan
either manually or through user programmed times.
Upon installation the user enters the correct longitude/latitude coordinates,
date, and local time. (See SETUP.) This ensures that once the schedules are
programmed, the load turns ON/OFF at the correct local times.
Lighted Switch
To help locate the switch button in a dark room, a green LED illuminates the ON/
OFF button while the controlled load is OFF. When the load is ON, the LED is OFF.
INSTALLATION & WIRING
WARNING
Disconnect power at the circuit breaker
before installing this product.
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 from the wall box.
2. Identify the type of circuit
In a single pole circuit, 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.

WARNING
Only connect the RT-24 to a Single Pole Circuit.
The RT-24 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.
3. Prepare the wires.
Tag the wires currently connected to the existing switch,
so that they can be identified 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” (approximately ½ inch).
4. Wire the time switch.
Twist the existing wires together with the wire leads on the RT-24 as indicated
in the table below. Cap them securely using the wire nuts provided.
Power wire from the circuit (hot)
to
Black wire on RT-24
Power wire from the lamp or fan (load)

turned ON before 10:00, then at 10:00 the load automatically turns OFF and the
program number that turned it OFF will replace MANUAL on the display.
