Again, press the HOUR button to advance the clock to the OFF time you want to set,
followed by the pressing the MIN key to complete the time setting.
Repeat Steps 1-4 to set additional ON/OFF times.
When finished, press the CLOCK button to exit programming mode.
Placing the Clock in Timer Mode
Press the SELECT button until the indicator bar, visible at the bottom of the screen, is above the
word AUTO. The clock will now turn Relay 1 or Relay 2 ON and OFF according to the ON/OFF
settings you have programmed.
Overriding the Timer Settings
You can manually turn Relay 1 or Relay 2 ON or OFF.
Press the SELECT button repeatedly until the indicator bar, visible at the bottom of the screen, is
above the word:
ON — to immediately power Relay 1 ON.
OFF — to immediately power Relay 1 OFF.
The clock will continue to operate in Manual Mode until you change the clock to Timer Mode.
Changing the Clock Battery
The factory-installed lithium clock battery will
last for years in normal service, and will rarely
need changing. In addition to this battery, an
internal nickel-cadmium battery — which
receives its charge from the main battery
— maintains clock settings for a limited time
when the main battery fails.
Use the following procedure to replace the
main battery.
Remove the timer from the enclosure,
allowing you to gain access to the rear of
the timer.
Using a small screw driver, pry the battery
holder from the back of the clock, as
shown.
Replace the battery with type CR2032, available wherever batteries are sold.
Place the new battery in the holder, then slide the holder back into the slot in the back of the
clock.
Reinstall the timer and make the connections.
