Your In-Home Display
Overview
The In-Home Display by Aztech Associates Inc. is a user-friendly product for monitoring energy consumption and its associated cost
within the home. It communicates wirelessly to the smart electricity meter installed on your home to present electricity used, its
estimated cost, and historical energy consumption. This guide explains how to use the In-Home Display and outlines what
information can be displayed.
The In-Home Display is lightweight and compact and is supplied with a power supply, so that you can place it in a convenient and
easy-to-view location. The color of the Light Bar (green, yellow, or red) is used to display different electricity rates at a glance and
the “speed” of its motion is proportional to the amount of energy you are consuming. The LCD display clearly shows numerical and
graphical information with the option to adjust backlight intensity for better visibility.
This manual reflects all the features available in the Aztech In-Home Display, your display may not have all the features shown.
Although efforts have been made to provide accurate electricity cost information, all electricity cost data displayed by the In-Home
Display is estimated for informational and educational purposes only and not for billing.

Note: Before operating in battery mode, the In-Home Display must operate on AC power only for at least 8 hours to charge the batteries.
Setting Language and connect to your meter
Start up
If turning on the IHD for the first time you will be asked to select a language. Select the language by
using the left ▲(UP) or right ►(DOWN) buttons to scroll. Press the √Button to make the desired
selection of the language of choice.
How to connect to your meter?
When the display attempts to connect to your meter, the Initialization Screen will be displayed with
the message “Acquiring Data”, indicating that the device is searching for a meter connection. During
this time, the Indicator Light Bar will glow red, sweeping back and forth. On the screen an antenna
icon will appear to indicate that the IHD is searching. When the meter connection is found, the
Summary view will be displayed. If no connection is found after 10 minutes, the message “No Signal
Found” will be shown. The device will continue to search for the meter connection. At this point, it is
recommended that the user ensure the Activation Code entered into the In-Home Display matches
that of the meter as described in the System Setup Menu section found in the Appendix.
To set or change the Activation Code during initialization, the Menu screens can be accessed at any
time by pressing and holding the right ►button. See System Setup Menu– Activation Code section
found in the Appendix.
The IHD talks directly to your Elster REX meter. Rex meters can be of two basic types and they talk to the IHD at different rates. Some
send values that are updated every minute although, if consumption is low, it may take several minutes or longer to notice any
changes. Some send the data every hour, so while instantaneous will give you real time feedback, the average display updates every
hour on the receipt of new data.

Light Bar
The Light Bar glows Red, Yellow or Green. The Light Bar light moves from left to right appearing to rotate at a rate that
corresponds to the amount of energy being consumed. The higher the rate of consumption, the faster the light will “turn”.
For Time-of-Use (TOU) the color is usually determined by the rate period and for volumetric use the colors are determined by
which block you are in as described in the typical example below.
•Green is typically used for the least expensive ($) TOU period or first volumetric block;
•Yellow is typically used for the mid-rate ($$) period or next volumetric block;
•Red is typically used for the most expensive ($$$) TOU period or volumetric block.
For single rate applications, the light bar glows one color only.
For more information about rates, see Electricity Rates in the Appendix.
Status line
The top status line (outlined in yellow)on this summary screen indicates the following:
MHS -Three possible views- Main, History or Summary. The highlighted letter is the current view.
Today’s date. This value is obtained automatically from the smart meter.*
An antenna icon indicates connection is established. When flashing, the signal is weak. When
there is no icon, the signal is lost.
AC indicator
Battery indicator. Note: A solid battery icon indicates battery operation only, not the amount of
charge remaining in the battery.
The present rate period indicator symbol is displayed
•eg. For TOU rates: $ = Off-Peak, $$ = Mid-Peak, $$$ = Peak, $$$$ = Critical Peak.
•eg. For volumetric $ = first block $$ = next block $$$ = etc.

Using your IHD
Your Summary
Your Aztech In-Home Display provides a choice of informative summary views. These screens enable you to track your usage from a
particular starting date and to how much energy you are using in different in different scenarios. Overall Summary presents your total
energy used in KWh and $. Both Overall and Detailed Summary information are automatically set to your billing date, but can be
adjusted to any date in the past if you want to monitor a specific period. To reset the summary screens, see Resetting Summaries. For
more information about changing the billing date, see Setting the Billing Date in the Appendix. The average daily comparison screen is
always based on a running week average and is not affected by the reset. The electricity rates are factory programmed. To view or
edit the costs, see Electricity Rates
Overall Summary
The Overall Summary view. The upper left highlights the “S” for the Summary view.
The total energy consumed and its associated estimated cost, since last Summaries Reset as shown
on the bottom line, is displayed. (This includes any base period rates such as a fixed monthly fee or a
per billing period fixed amount)
Detailed Summary (▲)
This screen displays the total energy consumed and its respective cost for each tier. This information is
as of the last Summaries Reset as shown on the bottom line. The sum of the kWh and $ columns add
up to the amounts displayed in the Overall Summary view (excluding monthly base charges). .
Average daily comparison (▲)
This view has two values shown. The upper “Today“ reflects the amount of electricity used today since
midnight. (up to the last complete hour - e.g. at 4:25 PM it shows use to 4PM) The bottom value “Week
Avg.” has the average of all the days in the last week for the same “midnight until now” period for
comparison. When your daily consumption for today is lower than the week’s average, a happy face will
appear.
NOTE: each value reads “0.0” when first turned on.
(√)Resetting Summaries
Pressing the √button in the Overall or Detailed Summary views accesses this menu.
NOTE: Each billing period the summaries will automatically be reset to your billing date. This can be
manually adjusted to any date in the past if you wish to monitor different period.
Now resets both the Overall and Detailed Summary views to zero. The Summary views will then begin
immediately with new cost and usage information effective from the moment of reset. NOTE: The dollar
cost includes consumption only unless the current day is a billing cycle start, in which case applicable
base costs will be included in the total dollar cost for that billing cycle.
By Date, causes a different screen to appear. The user will
be asked to “Set Start Date”, which is the date the Summary
information will be effective from, beginning at 12:01 a.m. on
that date. For example, if March 1, 2008 is selected for the
reset date, then the Overall and Detailed Summary views
will display the electricity consumed in kWh and $ from
March 1, 2008 until today. (the dollars is per kWh only
unless the selected period includes a billing cycle start, in which case any base costs will be included)
Any dates chosen before the date of installation for your In-Home Display will not contain any electricity
usage information. The date shown when viewing the Set Start Date screen is the last reset date used.
(typically billing period start) Dates cannot be set into the future.
NOTE: The difference between resetting to today’s date vs. resetting Now is the amount and cost of
electricity consumed from 12:01 a.m. today until now. (the dollars is per kWh only unless the selected
period includes a billing cycle start, in which case any base costs will be included)
Although efforts are made to provide accurate electricity cost information, ALL COSTS ARE ESTIMATES FOR INFORMATIONAL PURPOSES ONLY, NOT FOR BILLING.

Your Historical Usage
The Aztech In-Home Display allows you to view your historical energy consumption in a number of different ways. This allows you to
track your consumption goals in the short term (24hour) or long term (30 days).
Last 24 Hours kWh and (▲) $
The History view – Last 24 Hours kWh. The upper left highlights the “H” for History view.
This screen displays up to 24 vertical bars showing hourly consumption (kWh) for the last 24 hours. As
the day progresses the graph adjusts such that the most recent 24 hours of data is always displayed.
When a new bar of data is added to the right side of the graph every hour, the oldest data is removed.
The current time is shown near the top and the total amount (kWh) for the 24 hour time period is
displayed at the bottom left of the screen.

($) for the last 24 hours. Each bar contains the cost of electricity consumed during each hour-long
interval.
The current time is shown near the top and the total cost for the time period (not including any monthly
charges) is displayed at the bottom left of the screen
Last 24 Hours numerical history(▲)
This screen displays the consumption for the last 24 hours by TOU or volumetric block. Each row
contains the amount in kWh and cost of electricity consumed in $ for each TOU or volumetric block
shown. TOUs or blocks are shown in order. This does not include any monthly base charges.
(√)Last 30 days kWh and (▲) $
This screen displays up to 30 vertical bars showing the daily consumption (kWh) for the last 30 days,
excluding any data from the current day. As the week progresses, the graph adjusts such the most
recent day of data is always added to the right side of the graph and the oldest day’s data is removed
from the left.. The current date is shown near the top and the and the total amount of electricity
consumed in kWh for the 30 day time period is displayed at the bottom left of the screen.
The bottom scale is marked with “MWF” to identify the Monday, Wednesday and Friday daily bars; while
the bars for Saturday and Sunday are joined together into a double bar to easily distinguish weekends.
History – Last 30 Days $. This screen displays up to 30 vertical bars showing the cost of the daily
consumption in $ for the last 30 days. Each bar contains the cost of electricity consumed in each daylong
interval. The current date is shown near the top and the total $ amount for electricity consumed during
the time period (not including any monthly charges) is displayed at the bottom left of the screen.

Although efforts are made to provide accurate electricity cost information, ALL COSTS ARE ESTIMATES FOR INFORMATIONAL PURPOSES ONLY, NOT FOR BILLING.

Your Real-time Usage
Your Aztech In-Home Display provides the unique ability to show your real time usage in three viewing options. Your real time usage is
updated at a rate determined by your meter although, if consumption is low, it may take several minutes or longer to notice any
changes on the Current Usage and Light Bulb views. The instantaneous view always gives immediate response.
Current Usage(▲)
The Main view – Current Usage.
The value is typically updated every few minutes and represents the average amount of electricity in
kilowatts that is presently being used. (Demand) The bottom number in the smaller font represents the
cost of electricity use per hour at the present rate of consumption. (based only on variable costs)
Light bulbs(▲)
Each light bulb represents 100W of electricity being used and corresponds to the number displayed in
the previous screen rounded down to the nearest 100W increment. If the amount of electricity is greater
than the number of light bulbs that can be displayed (60 bulbs, >6000 W), the view will revert to the
Current Usage view.
Instantaneous(√)
In this display, the smart meter is queried once every six seconds and each real-time electricity demand
value is displayed in kW. After a total of five queries over approximately 30 seconds, the display reverts
back to the average demand in Current Usage view shown above.
