countdown cycle. Switches the load OFF
when the timer is ON.
Pressing the ON/OFF key twice in less than 1
second or operating the remote (3-way)
switch twice in less than 1 second (for 3-way
applications) when the load is ON, will restart
the timed interval without switching off the
load. This is desirable when controlling high
intensity discharge lighting.
Pressing and holding the ON/OFF key when
the load is ON will shorten the interval that is
in progress. The timer will continue counting
down from the time that shows when the
ON/OFF key is released. This does not disturb
the preset interval.
WARN – Selects warning by audible signal
( ), flash of lights for lighting loads (the
word FLASH appears), both audible and flash,
or neither. Note that the timer is factory set for
neither. If flash is selected, the load turns off
for 2 seconds, 3 minutes before the load is to
switch off. If audible is selected the timer
beeps every 30 seconds, starting 3 minutes
before the timer is to switch off.
HOLD – Pressing this key switches the load
ON indefinitely. Pressing HOLD again,
pressing the ON/OFF key or operating the
remote switch (for 3-way applications)
switches the load off. Not normally used for
commercial applications.
