Appliance Communication Module (Acm) - GE GeoSpring GEH50DEED Owner's Manual

A liance Communication Module (where installed).
The Hybrid Electric heat pump water heater is compatible
with the GE Smart Appliance communication module (ACI_
which can be purchased separately. Contact your local utility
or visit www.GEAppliances.com/Smart-Appliance to see if
your area is using ACMtechnology. Applying the ACH 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.
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:
o "Low" (represents lowest energy cost rate is available)
"Hedium" (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 LED if 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 Medium, the control will operate
in Heat Pump (only) Mode and the water temperature
will remain at the current user setting. If the current user
temperature setting is 120°F the screen will display:

When the
ACM signal is High, the control will operate in Heat Pump
(only) mode, with a water temperature setting of 110°F, 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
100°F, and the screen will display:
Notice: Appliance ACM connection carries voltage not
compatible to computers or accessories. Do NOT plug
laptops, modems, touters, 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 is operating in medium, high or critical, the LCDabove
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 18 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.
