Congratulations on the purchase of your new Smart Energy
Thermostat! The thermostat is designed to help you save money and
conserve energy. When connected to a smart meter, you can use
the product to get real-time access to information about energy
consumption in your home so you can make more informed decisions
and better manage your energy use.
This thermostat may have been installed in conjunction with a plan
from your utility designed to help you save money and/or to ensure
grid reliability. Two prevalent utility plans are:
In a Direct Load Control (DLC) plan, you voluntarily allow your utility company to
control major appliances in your home when demand for electricity peaks. These
instances of peak demand are called “utility events” and when they occur, the
utility will take action, such as adjusting the thermostat temperature or cycling
your air conditioner on and off, for the duration of the event. These events are
relatively infrequent and under most circumstances, you will have the option to
opt in or opt out of the event. (To view thermostat features exclusive to Direct
Load Control plan customers, see page 24-26.)
In a tiered pricing plan, electricity rates fluctuate with demand during the course
of each day. You can determine - in advance - how you want your thermostat to
respond when prices change. You may decide it’s worth giving up a few degrees
of comfort to save money when rates reach a certain level. (To view thermostat
features exclusive to Tiered Pricing plan customers, see page 20-23.)

With just one touch, the AWAY preset will instantly change your desired
temperature to a set point that will save you money. This is a convenient feature
when you’re leaving home unexpectedly or intend to be away from home for an
extended period of time. The unit has been shipped with “Away” settings based
on Energy Star recommendations of 85° in the summer and 62° in the winter, but
those temperatures can easily be changed with
the touch of one key.

This feature lets you establish low and high temperature limits that cannot be exceeded.
This can be particularly helpful if you want to prevent children or tenants from adjusting
the thermostat beyond a level acceptable to you. The unit has been shipped with default
set point limits of 45° minimum cooling and 99° maximum heating.
Temperature Display Adjustment:
Menu > Settings > Advanced Settings > Temp Display Adjust
Your thermostat was accurately calibrated at the factory. But if you’d like the displayed
temperature to be higher or lower than the actual temperature, this feature lets you adjust
the displayed temperature.
Key Pad Beeper:
Menu > Settings > Advanced Settings > Key Pad Beeper
This feature activates a sound each time a thermostat key is pressed. This feature is OFF
by default. To turn the feature ON, select KEY PAD BEEPER from the menu and press the
key.
Comfort Recovery:
Menu > Settings > Advanced Settings > Comfort Recovery
The COMFORT RECOVERY feature activates heating or cooling in advance of the set schedule.
If, for example, you set the 7:00 am temperature to 68°, COMFORT RECOVERY begins the
process of heating or cooling in advance, so the room temperature reaches 68° by 7:00.
This feature is OFF by default. To turn the feature ON, select COMFORT RECOVERY from the
menu and press the key.

The first step toward monitoring your energy use is to set a monthly budget target or cost
threshold, that when met will generate an alert. Think about how much would you like to
spend each month for electricity. Say, for example, your target is $100 per month. The
thermostat is capable of monitoring your energy use and notifying you when you have
exceeded this monthly threshold. To establish a monthly target, take these steps:
4.0 Monitor Whole-Home Energy
Use When Connected to a Smart Meter
When the thermostat is connected to a smart meter, it will help you track your entire home’s
energy use - not just the electricity being used by your heating and cooling equipment. And
by giving you a detailed view of usage in real time, you can take action to increase your level
of energy efficiency - preserving resources and saving money. In this section, you’ll learn how
to set a monthly target for energy use and how to track your use against that target.
4.1 Set Monthly Budget Target
To take advantage of the energy monitoring features, the thermostat must establish
communication with your utility. In most instances this will mean that your home must be
equipped with a ZigBee enabled smart meter. If you aren’t sure if you have this type of meter,
contact your utility company.
If you have established a wireless connection with the meter but certain features listed below
do not appear in the Energy menu, or you see an error message reading “data not available”,
then chances are the meter doesn’t support the specific data set required for the feature.
KEEP IN MIND:
Set a monthly budget target start date:
Energy > More > Set Monthly Budget > Billing Cycle Start Date
From the START OF BILLING CYCLE
screen, use the arrows to identify
the date of the month that you’d like a
target cycle to begin. When your date is
selected, press .
Start of Billing Cycle
Day of the month that my billing
cycle starts
1

16
The product will start measuring your energy consumption immediately upon connecting it to a
smart meter or other data source. By default, the counter will reset to
$0
on the first calendar
day of every month. For a closer approximation of how you’re tracking against your monthly
bill, you can change the start date to correspond with the first day of your billing cycle (which
can usually be found on your utility bill).
KEEP IN MIND:
You may want to set the target slightly lower than the total amount you’d like to pay, to
accommodate fees and taxes that may be added to your electricity bill.
KEEP IN MIND:
Set a monthly budget dollar target:
Energy > More > Set Monthly Budget > Monthly Budget
Ideally, how much would you like to spend each month for electricity?
From the MONTHLY BUDGET screen,
use the arrows to set the dollar
value of the monthly target budget.
When the dollar value is selected,
press .
From the ALERT BEEPER screen,
determine if and how you want to
be alerted that you have reached
your target budget threshold. The
beeper can be off, set to beep once
when the alert occurs, or every 15
minutes until you press a key. Use the
to highlight your selection then
press .

Once you have set a budget target, the following features are designed to help you track

To view month-to-date usage:

Press the ENERGY key.
STEP 1
The month-to-date usage chart shows
energy use for each day of the current
month. The top line shows you how
much energy you have consumed so far

To take advantage of the budget tracking feature, your meter must be configured to provide
electricity rate information. If your meter does not support rate information, then this screen
will simply show your energy usage measured by kWh. To estimate your month-to-date energy
costs, you will need to multiply the kWh value shown on the product display by your kWh rate
which can likely be found on your electricity bill.
KEEP IN MIND:

18
From the CURRENT COST PER HOUR
screen, you’ll see the current cost per
hour kWh, the rate at which you’re
currently using electricity and the
cost per kWh.
To view current cost estimates:
Energy > More > Current Cost Per Hour
Want to know how much it costs to run your dryer? The CURRENT COST PER HOUR feature
will allow you to figure out how much it costs to operate any electrically powered appliance
or device in your home. This feature shows your whole home’s energy use in real time. First,
take a look at the screen and note your energy use. Then, start the dryer and check back to
see the cost difference. Unless other appliances turned on while you were starting the dryer,
you can infer the difference between the original and new “cost per hour” values is what it
costs you per hour to run the dryer.
To view HVAC cost estimate:
Energy > More > HVAC Cost Estimate
Heating, ventilation and air conditioning (HVAC) account for almost half of all residential
energy consumption. The HVAC COST ESTIMATE screen lets you see how much you’re
spending on electricity to run your HVAC equipment and how much it contributes to your
total electricity costs.
Current Cost Per Hour
Current Use 3.4 kWh
Cost Per Hour $0.41
Current Rate $0.12 kWh
From the HVAC COST ESTIMATE SCREEN,
