After the desired temperature setting has been selected, press ENTER to accept the setting. If the water temperature setting is
changed and the ENTER key is not pressed to accept it after 10 seconds of no control activity, the control will automatically revert to the
previous temperature setting.
D. ADJUSTING THE FUNCTION MODE
This water heater defaults to the Auto operating Mode. The Auto Mode is the recommended setting for this water heater, but can be
changed if desired. Available modes are listed below and can be found by pressing the MODE button when the water heating control is
unlocked.
Economy Mode
The Economy Mode is the most energy efficient. This mode takes heat from the surrounding air to heat the water. It takes more time to
heat water in Economy Mode, so this mode may NOT be sufficient in a high-demand situation, such as a large household or company.
Standard Electric Mode
This mode uses only the upper and lower heating resistance elements to heat water. It takes less time to heat water, but Standard
Electric Mode is also the LEAST efficient operating mode on the water heater.
Auto Mode
– FACTORY RECOMMENDED SETTING
Auto Mode combines the energy efficiency of the Economy Mode with the recovery speed and power of Electric Mode. Auto Mode is
recommended for normal water usage.
To access any of these modes:
1. Press and hold the ENTER key for three seconds to unlock the key pad.
2. Press the MODE button.
3. Select the desired operating mode by using the UP and DOWN keys to scroll through the options.
4. Once you’ve selected an operating mode, press the ENTER key or wait ten seconds for the Auto-Confirm Function to automatically
accept the mode.
E. 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
o
F 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.
3. 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.
For example, if you will be gone 14 days, select 14 with the key pad. The water heater will then automatically drop the water
temperature to 50
o
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.
Control Lock
The key pad can be locked out to prevent accidental key inputs. Simply press and hold the ENTER button for three seconds. The
display will show “controls are locked” and the green light will be lit. No other key presses will be allowed when the controls are locked.
To deactivate the lock, press and hold the ENTER key for three seconds. The green light will fade and the screen will go to the default
display.
F. USING THE BUTTONS IN COMBINATION
1. Temperature Measurement Conversion
The display defaults to temperature readings in Fahrenheit (F). To show the temperature in Celsius (C) press and hold the ENTER and
MODE buttons simultaneously for one second. To change from C to F, repeat the process.
