Programming the schedule
You can set up to 7 programs. To set a program, you need to enter its start time (ON) and its
end time (OFF).
1)
Pry the switch door open using a small screwdriver.
2)
Press the PGM button to display a program and its On or Off time.
For example, when you first press PGM, program number 1 (P1) and
its On time (ON) will appear. - : - - will appear instead of the time if
the program is not set (inactive).
3)
Press the DAY button to select the day to which you want to apply
the program.
4)
NOTE: If you want to apply the program to every day of the week,
press DAY until all the days are displayed. (This still counts as 1
program, not 7)
5)
Press the HOUR and MIN buttons to set the ON time (time when you want the lights to
turn on). If you have selected the 12-hour format, ensure that PM appears on the
screen when an afternoon time is displayed.
6)
After you have programmed the ON time, press the PGM button to display the OFF
time (time when you want the lights to turn off).
7)
Repeat steps 3 through 5 to program the OFF time. If the program
ON time is set for every day of the week, the program OFF time will
automatically be set for every day.
8)
To set another program, repeat steps 2 through 6. Programs that are
not set will remain inactive.
9)
Press one of the control buttons or close the switch door to return to normal operation.
Clearing a programmed time
Press the PGM button as many times as needed to display the programmed time. Hold the
PGM button for 3 seconds. - : - - appears when the programmed time is erased.
Troubleshooting
Blank display
Faded or irregular display
Cannot switch between 24-hour format
and 12-hour format
Programs do not run as expected
The switch resets itself without apparent
reason when used to control an inductive
load such as a relay or a contactor.
• Verify circuit breaker at main panel.
• Ensure the ON/OFF selector is at ON.
• Reset the switch using a paper clip.
Ambient temperature below freezing point
First, press one of the control buttons so that MAN or
AUTO appears on display.
• Make sure the switch is properly programmed.
• Note that - : - - indicates an inactive program.
• If the switch has been configured for
12-hour format, check that PM appears on the left side
of the screen when an afternoon time is displayed.
The reset is caused by the load. Install a snubber
(AC130-03) at each relay/contactor.
