Module (Acm) - GE Appliances Geospring GEH50DEEDXX Owner's Manual And Installation Instructions

Appliance Communication Module
(where installed).
The Hybrid Electric heat pump water heater is compatible
with the GE Smart Appliance communication module
(ACM)which can be purchased separately. Contact
your local utility or visit www.GEAppliances.com/Smart-
Appliance to see if your area is using ACM technology.
Applying the ACI v i allows the unit to respond to utility
signals or to join a home network.
The following demand response features may be available
as part of a pilot test program with the local utility
company to help consumers reduce peak electricity
usage in the home.
When the ACM signal is Medium, the control will operate
in Heat Pump (only) 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):
INSTALLATION
The ACM 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 ACM module is plugged into the
water heater's connection, follow the power-up directions
included with the ACM module. As soon as the ACM
module is operating, the heat pump water heater is ready
to receive the ACM signals.
QUICK GUIDE
If your local utility company is utilizing ACM technology,
the ACM module will receive the signals sent from your
utility company. One of four signals will be sent:
• "Low" (represents lowest energy cost rate is available)
• "Medium" (represents increased energy cost rate)
• "High" (represents increased energy cost rate)
• "Critical"(represents "peak rate" energy cost rate)
A heat pump water heater equipped with a ACM 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, the LED light above the Power Saver button will be
on, indicating energy pricing periods are in effect, and the
letters PSwill be displayed on the LEDif the user attempts
to change the temperature without first pressing the
Power Saver override button.
When the signal is low or when no ACM 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 ACM signal is High, the control will operate in
Heat Pump (only) mode, with a water temperature setting
of Zl0°F (43°C),and the screen will display:
When the ACM signal is Critical, the control will operate in
Heat Pump (only) mode, with a water temperature setting
of Z00°F (38°C),and the screen will display:

Notice: Appliance ACM connection carries voltage not
compatible to computers or accessories. Do NOT plug
laptops, modems, routers, etc into the Appliance RJ45
ACM connector. Use only with designated GE Appliance
Accessories. Connection to computers and accessories
may result in product damage.
When unit isoperating in medium, high or critical, the LCD
above the Power Saver button will be lit. If at any time you
want to change the temperature setpoint while the unit is in
Power Saver mode, press and hold the Power Saver button to
override the Power Saver mode, then use the arrow buttons
to change to the desired setting. Override will be in place
for Z8 hours. If you try to change the temperature without
overriding the powersaver function, the letters PSwill show on
the display, indicating it is still in Powersaver mode.
