Operational Modes - GE GeoSpring GEH50DEEDXX Owner's Manual & Installation Instructions

Operational Modes.

This water heater defaults to the Hybrid operating
mode. Available modes are listed below and can
be selected using the MODE button.
Heat Pump (only) Mode
MAXIMUM SAVINGS
Heat Pump (only) 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 sufficient if you have a high-demand
situation such as a large household or company.
Hybrid Mode
Hybrid mode combines the energy efficiency of
Heat Pump (only) with the recovery speed and
power of the Electric (Fan off)/Standard (Fan off)
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: Reported unit performance, energy
consumption and savings are based on Hybrid
Mode operation at a temperature setting of 135°F
(57°C).
High Demand/Boost
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 (Fan off)/
Standard (Fan off) 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 mode is that in High Demand
mode the heating resistive elements are activated
sooner than in the Hybrid mode.
Electric (Fan off)/Standard (Fan off) 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 less in this mode, but it
is the LEAST energy-efficient mode.

—RECOMMENDED FOR
Vacation
This feature is used when you will be away from
the home for an extended period of time and hot
water is not needed. In this mode, the unit will drop
the water temperature down to 50ºF (10°C) 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 14 days, follow
these steps:
1. Select VACATION by using the Mode button
2. Input total days you will be gone (in this
example, 14) by pressing the UP arrow button
(the default is 7 days)
3. Press ENTER.
The unit will drop the water temperature down to
50ºF (10°C) for one day less than you will be gone
(in this example, for 13 days). At the end of the
day before you return (in this example, the 13th
day), it will automatically return to the previous
operating mode and heat the water to the original
temperature setting so hot water is available
upon your return.
To access any of these modes:
Press the MODE button on the control to the
1
desired operating mode.
The green light will be illuminated on the
2
chosen mode.
