ABOUT THE USER INTERFACE FEATURE BUTTONS
Vacation Mode
This feature is used when you will be away from home for an extended period of time. In this mode, the unit
will drop the water temperature down to 50 ºF and use the most efficient heating mode to conserve energy
while the water heater is sitting idle. The unit will automatically resume heating one day before your return,
so hot water will be available.
To use Vacation Mode:
1.
Press and hold the ENTER key for three seconds to unlock the key pad.
2.
Press the VACATION button.

Press the UP and DOWN arrow keys to select the # of days you will be away (default is 7 days). Then, press
the ENTER key or wait ten seconds for the Auto-Confirm Function to automatically accept the number of
days.

drop the water temperature to 50
°
F for 13 days. At the end of the 13
th
day, the water heater will
automatically return to the previous operating mode and heat the water to the original temperature setting.
The green light will be lit when this feature is on, indicating that the control is locked.
