TIME & DATE
The control uses an internal clock for the night setback feature and for logging of events. For these features to
work correctly, the clock must be set when the water heater is first installed or anytime the water heater has been
powered off for more than 30 days.
The date and time are displayed as “YY:MM:DD W hh:mm”.
YY = year
MM = month
DD = date
W = day (1 = Sunday, 2 = Monday, etc.)
hh = hour (24 hour time; 2:00 PM = 14:00)
mm = minutes.
The date and time are set using the Up, Down, Previous and Next buttons. Once set, the Enter/Reset button
should be pressed to save the setting.
NOTE: The clock does not automatically adjust for Daylight Saving Times and therefore will require a manual
adjustment.

NIGHT SETBACK TIME
If the Night Setback Temperature is set to anything other than 0
°
C, the night setback feature becomes active.
This will require start and stop times to be programmed for the days that reduced temperatures are required.
Each day of the week (Sunday through Saturday) will have an on and off time. Using the Previous and Next
buttons the desired time slot (e.g. Monday ON, Monday Off, Tuesday On etc.) can be selected. Once the desired
time slot is selected, the Up and Down buttons can be used to set the required time.
Example: Monday ON: 22:30, Tuesday OFF: 6:45. If you wish to skip a day and have no night setback, leave the
on and off times the same. The default times for each day will be 00:00 (midnight).
