Operational Modes

This water heater defaults to the Hybrid operating mode.
To select available modes listed below:
desired Operating Mode is illuminated.
In Hybrid Mode and High Demand/Boost Mode, the
heating elements are active, such as during the initial
recovery from a large draw. This is normal and does not
indicate an operating issue.

have a high-demand situation such as a large household
or company.
Hybrid Mode
Hybrid mode combines the energy efficiency of Heat
Pump with the recovery speed and power of the Electric/
Standard mode in most water usage situations. Hybrid
mode will allow the unit to perform like a standard
electric water heater while providing significant energy
savings.
NOTE: Energy Guide unit performance, energy
consumption and savings are based on non-ducted
installations in Hybrid mode at required Department of
Energy (DOE) test conditions. Operating in Heat Pump
mode may provide a greater savings in energy and
operating costs than the claimed savings.
High Demand/Boost Mode
This mode may be necessary if your household has a
higher-than-average water usage or the unit is undersized
for the household water demands. In this mode, the unit
will use the electric heating elements only when the water
demand rate is high. When using the heating elements,
the water temperature will recover at a faster rate but it
will use more energy to heat it. Unlike Electric/Standard
mode, it will use the heating elements only when needed,
and use the heat pump when water demand rates are
lower.
NOTE: The difference between Hybrid mode and High
Demand/Boost mode is that in High Demand/Boost mode
the heating resistive elements are activated sooner than
in Hybrid mode.

Electric/Standard Mode
This mode uses only the upper and lower heating
resistance elements to heat the water, stopping the cool
air discharge during heat pump operation. The time it
takes to heat the water is less in this mode, but it is the
Follow these steps to set Electric/Standard mode:
1. Select Electric/Standard mode using the MODE
button.
2. Input the total days to remain in Electric/Standard
mode using the UP arrow. The default is 3 days,
3. Press ENTER
At the end of the selected time period, the unit will switch

water temperature setting to 50ºF (10°C) and will use the
heater is sitting idle. The unit will automatically resume
heating one day before your return, so that hot water will
be available.
To set Vacation Mode:

mode for 14 days using the steps above. The
temperature setting will automatically reduce to 50
(10 0 C) for 13 days. At the end of the 13th day, the
previous operating mode and temperature setting will
reset to ensure hot water is available upon your return.
Extended Shutdown Periods
of time, the power and water to the appliance should
be turned off and the water heater drained to conserve
energy and prevent a buildup of dangerous hydrogen
gas. This unit has no power button, power can only be
shut off at the circuit breaker or disconnect switch.
If the water heater has an anode depletion sensing
feature (some models) and the water heater cannot be
drained, it is recommended to leave the power turned
on with the water heater in vacation mode to ensure that
the feature will continue to operate properly while still
conserving energy.
The water heater and piping should be drained if they
might be subjected to freezing temperatures.
After a long shutdown period, the water heater's
operation and controls should be checked by qualified
service personnel. Make certain the water heater is
completely filled again before placing it in operation.
NOTE: Refer to the Hydrogen Gas Caution in the
Operating Instructions (see page 3).
