DEFAULT PROGRAM
The controller does not require a default program
after a power outage. The controller has non-
volatile memory to retain your custom program.
Four AAA Alkaline batteries maintain the real time
clock and calendar. (Batteries should be changed
annually.) Should there not be sufficient battery
power to maintain the real time clock and calendar
and there is a power outage; when the electrical
power returns, the controller will default to
midnight and Saturday.
Note: The controller will Run scheduled
programs according to the displayed Day and
Time.
ELECTRICAL AND BATTERY POWER
Loss of Power: The letters “NO PO” will be
displayed when the electrical power to the timer
has been interrupted. Check connections and
power supply.
Low Battery: The letters “LO PO” will be
displayed when the battery life is below
recommended levels. All four batteries should be
replaced.
