Installation
1. Read the operating instructions carefully.
2. Check the input and output ratings marked on the
unit to make sure this product is suitable for your
application.
3. Disconnect power supply prior to installation to pre-
vent electrical shock.
4. Damage to the contacts caused by short circuiting
will void warranty.
5. Wire in accordance with National and local electri-
cal code requirements.
BE SURE ALL CONNECTIONS ARE SECURE.
DOUBLE CHECK ALL TWIST-ON WIRE CON-
NECTORS.
6. Mount timer into wall box using supplied screws.
7. If timer does not operate, check that the timer’s black
wire is connected to hot line and not the load. If nec-
essary, reverse connections to red and black wires.
Manual Operation
The slide switch provides manual operation of the
load, overriding the timer. If set to the position, the
load will be continuously off, and if set to , it will be
continuously on. For automatic timed on’s and off’s,
the switch must be in the position.
Programming
The timer dial contains 72 “trippers” which, when set
at the inner perimeter of the dial, will turn the switch
“ON” at the time adjacent to the tripper. The switch will
return to the “OFF” position when the timer progresses
past the inward trippers.
The 72 trippers allow multiple on/off sequences with a
minimum on or off time of 20 min. To program, set all
trippers inward for the duration of the on event.
For example, to turn lights on at 5:00pm and off at
11:00pm, leave inward the 18 trippers between 5 and
11 on the “pm” side of the dial. Make sure manual
switch is in the position.
NOTE:
For any times where “OFF” programming
is desired, the trippers must be moved to the outer
perimeter of the dial.
Setting The Time
Rotate the dial
clockwise
until the correct time and
“am” or “pm” is opposite the arrow on the plate.
CAUTION: Do not turn dial counter-clockwise, as the
timer will be damaged.
