ADJUSTING THE WATER TEMPERATURE AND FUNCTION MODE
This water heater defaults to the Hybrid operating mode. The Hybrid mode is the recommended setting for this water
heater, but can be changed if desired.
Eco Mode
Eco is the most energy-efficient mode for this water heater. It takes heat from the surrounding air to heat the water.
The time it takes to heat the water is longer in this mode, so it may NOT be ideal if you have a high-demand situ-
ation such as a large household or company.
Electric Mode
This mode uses only the upper and lower heating resistance elements to heat the water. The time it takes to heat the
water is reduced in this mode, but it is the LEAST energy-efficient mode.
Auto Mode —RECOMMENDED MODE
Hybrid Mode combines the energy efficiency of eHeat™ with the recovery speed and power of the Standard Electric
mode, with normal water usage.
ABOUT THE FEATURE BUTTONS ON THE USER INTERFACE
Vacation
You may use this feature when traveling away from home for an extended period of time and hot water won't be
needed. In this mode, the unit will drop the water temperature down to 50ºF and will use the most efficient heating
mode to conserve energy while the heater is sitting idle. The unit will automatically resume heating one day before
your return, so that hot water will be available. For example, if you will be gone 7 days, press the VACATION
button, press the UP arrow button until the display reads "7 days" (the default is 7 days) and press ENTER. The unit
will drop the water temperature down to 50ºF for 6 days. At the end of the 6th day, it will automatically return to
the previous operating mode and heat the water to the original temperature setting. The green light will be
illuminated when this feature is ON.
