The Hybrid Electric heat pump water heater is compatible
with the GE Smart Appliance module (SAM) which can
be purchased separately. Contact your local utility or visit
www.GEAppliances.com/Smart-Appliance to see if your
area is using SAM technology.
The following demand response features are available
as part of a pilot test program with the local utility
company to help consumers reduce peak electricity
usage in the home.
INSTALLATION
The SAM module is equipped with magnets in the base
of the module that will enable it to be attached to the
painted metal exterior of the heat pump water heater.
details on how to connect the cables to the module are
in the instructions that come with the module.
Once the cable from the SAM module is plugged into the
water heater’s connection, follow the power-up directions
included with the SAM module. As soon as the SAM
module is operating, the heat pump water heater is ready
to receive the SAM signals.
QUICK GUIDE
If your local utility company is utilizing SAM technology,
the SAM module will receive the signals sent from your
utility company. One of four signals will be sent: “Low”
represents that the lowest energy cost rate is available,
“Medium” and “High” signals represent increasing energy
cost steps, and the Critical signal represents “peak rate”
energy. A heat pump water heater equipped with a SAM
module will automatically recognize what energy cost
rate is available and adjust its mode and temperature
setting to use less energy when rates are medium, high
and critical. When the heat pump water heater responds
to these signals, it will display the letters “EP” in the screen,
along with other information, indicating that energy
pricing periods are in effect.
When the signal is low or when no SAM module is
connected, the unit runs as normal. The following steps
show how the unit reacts to Medium, High and Critical
signal levels.
When the SAM signal is Medium, the control will operate
in eHeat™ Mode and the water temperature will remain
at the current user setting. The screen will display the
following (where xxx is the current user temperature
setting):
When the SAM signal is High, the control will operate in
eHeat™ mode, with a water temperature setting of 110°F
(43°C), and the screen will display:
When the SAM signal is Critical, the control will operate in
eHeat™ mode, with a water temperature setting of 100°F
(38°C), and the screen will display:
