Description
The Intermatic Model ET716CK is an Electronic
Seven Day TIme Switch with Photo Sensor Enable.
Loads can be automatically switched ON or OFF
according to a programmed schedule, providing
appropriate light levels exist. The Photo Enable func-
tion ensures that loads are ON only if the ambient light
level is low enough to require lighting and only if the
user programmed schedule is switched ON. This timer
is not designed to directly switch loads over 5 amps or
tungsten (lamp) or other high inrush loads. The pro-
gram will allow up to 28 set points (14 ON/ 14 OFF)
with up to 196 set points by using repeat daily cycling
for a seven day schedule. The photo sensor assembly
includes a sliding bracket which can be adjusted to
partially shield the photo cell, thereby increasing the
light level at which the load will switch ON and OFF.
The photo sensor can be located up to 1,000 feet from
the electronic time switch using ordinary 18 AWG bell
wire.
CAUTION: Connections made to the photo sensor
inputs,
must be made outside of the enclosure and
made using UL listed 14 to 18 AWG wire. DO NOT
apply power to the photo sensor inputs.
