DESCRIPTION AND OPERATION
The RT-200 is an astronomic time clock and timer switch 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. This ensures that once the schedules
are programmed, the load turns ON/OFF at the correct local times. The button switch is a customizable manual override feature with a
default countdown of 2 hours.
Lighted Switch
To help locate the switch button in a dark room, an amber LED illuminates the ON/OFF button while the controlled load is OFF. When
the load is ON, the LED is OFF.
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 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.
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 Gauge”
(approximately ½ inch).
