THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED TECHNICIAN.
WARNING
HAZARDOUS VOLTAGE: Risk of electric shock. Can cause injury or death. Heater may be connected to more than one branch circuit. Disconnect power to all circuits before servicing.
NOTE: Battery back up in 120V time clocks is approximately 3 days. However, the battery in this clock is rechargeable once power is applied. 240V time clocks have a 5-8 year battery back up. The battery in this clock is not rechargeable.
NOTE: Throughout the programming of the time clock, if there is approximately 40 seconds of inactivity (no buttons are pushed), the display will automatically reset to normal operation. If the clock resets and the program information you are entering or editing is not stored, the time clock will default to the previous settings. The new information will have to be reprogrammed.
SETTING THE TIME CLOCK
NOTE: If "dat", "dat 1", "dat 2", "dat 3", or "no" is currently displayed, omit Step 1.
Hold the "
" Button
Press and hold the "" button. Then press and hold the ”d” button until the display reads either "dat”, "dat 1”, "dat 2”, "dat 3”, or "no”. Then, release the buttons.
Set Daylight Savings
To set daylight savings time (DST), press the "C1” button until "dat 3” appears (DST for North America). If DST is not to be recognized, press the "C1” button until "no” is displayed and proceed to Step 5.
NOTE: Do NOT use "dat 1" or "dat 2" as they are used to set DST in other parts of the world.
Set the Year
To set the year, press the "Prog” button once and a year will be displayed. Press the "d” button until the current year is displayed.
NOTE: The year can be set from 1994 to 2039. If you happen to pass the current year while setting the clock, continue to press the "d" button. After the year 2039, the clock will start over at 1994.
Set Month and Day
To set the month and day, press the "Prog" button again and four digits will be displayed. Press the "d” button to program the day of the month in the two digits on the left, and the "m” button to program the month in the two digits on the right.
NOTE: If daylight savings time was set to be recognized in Step 2, a snowflake or a sun will appear in the clock display after the "Prog" button is pressed again. A snowflake indicates winter months (days between the last Sunday in October and first Saturday in April). A sun indicates summer months (days between the first Sunday in April and last Saturday in October).
Set Day of the Week
To set the day of the week, press the "Prog" button again. The day of the week should automatically be indicated by an arrow (1 = Monday...7 = Sunday). If the day is not indicated by an arrow, press and hold the "" button. While holding the "
" button, press the "d" button until the correct day of the week is indicated.
NOTE: Do NOT release the "" button before pressing the "d" button or the clock will have to be reset, and you will have to start from the beginning with reprogramming.
Set the Time
To set the time, press and hold the "" button. Use the "h" button to set the hour and the "m” button to set the minute. Release the "
” button when the time is set.
NOTE: 240V time clocks display time in military time. (0:00 is 12:00 am, midnight.) 120V time clocks display time in non-military time (am and pm hours).
