is used in your home:
Off: Heating and cooling systems are off. The fan may still run for home ventilation.
Cool: (Available only if you have cooling equipment.) The thermostat controls only the cooling
system, which runs as needed to bring the home to the target cool temperatures in the
schedule.
Heat: (Available only if you have heating equipment.) The thermostat controls only the heating
system, which runs as needed to bring the home to the target heat temperatures in the
schedule.
Auto: (Available only if you have both heating and cooling equipment.) The thermostat
automatically selects heating or cooling, to bring the indoor home temperature to the target
temperatures in the schedule.

Foundation User Guide
May 2012 Page 22
3.5.2 Default Schedule
Foundation is pre-programmed with an energy-efficient temperature schedule. You can change the
default schedule according to your comfort and schedule needs.
The default Foundation schedule uses up to four times, called setpoints, each day to adjust the target
temperature. Generally, these times correspond to most people’s daily schedules:
Wake, Leave, Return, and Sleep.
Each setpoint has a start time. Start times can vary for each day, but the default start times are different
for weekdays and weekends.
You can change the target heating and cooling temperature for each setpoint. The thermostat
determines the time required to reach the target temperature. It starts to run the equipment and adjust
the temperature before the start time for the temperature change, so that it reaches the target
temperature by the start time.
For more information about anticipation time, see 6.1.5 Control.
Note: Default schedule may not be as shown.

Foundation User Guide
May 2012 Page 23
3.5.3 Set a Schedule with the Wizard

The Schedule Wizard is a step-by-step guide that schedules temperature settings for each setpoint. It
allows you to set the heating and cooling temperatures for the Wake, Leave, Return, Sleep, and
Weekend setpoints. It also allows you to set the start times for those setpoints.
To save electricity costs, adjust the temperature when you are away during the day. The
thermostat adjusts the temperature back when you return. The more you adjust the
temperature, the more you will save. Remember to adjust the temperature at night as well.

4 Energy Mode
You can use Foundation to help manage your energy consumption. To avoid power outages and rising
energy costs, your utility may send pricing information or energy events to manage energy use in your
community. Customers who participate in these events can reduce their energy consumption and save
money.

Foundation User Guide
May 2012 Page 35
4.1 Energy Home Screen
The Energy home screen provides at-a-glance consumption data and access to historic data and energy
consumption information to help you make informed decisions about your home comfort and energy
consumption.
A star next to the price indicates that you are not receiving price information from your
electricity service provider. When the price comes from the electricity service provider, there is
no star next to the price.
Link status:
o Indicates that the link is connected. The signal quality ranges from the lowest
signal quality (1 bar) to the highest signal quality (5 bars).
o Indicates that the link is not connected.
The source for the energy consumption data is either HOME or HVAC:
o HOME: The consumption data comes from the meter. Foundation displays the
electricity consumption for the whole home.
o HVAC: The consumption data comes from the thermostat. Foundation displays the
electricity consumption for only the heating and cooling system. The data is based on
the load information that is entered in the Energy Settings menu. For more information
about the load information, see 4.7.3 Load Information for your HVAC .
The current energy use reflects the amount of energy that is being used in the home in
kilowatts (kW).
To see how low your current energy use can go, turn off the lights and unplug your
electronic devices when everyone is away or asleep. The lower this value is, the more
you will save.
The cost per hour is how much it costs you to consume that amount of energy for one hour.
The scrolling message indicates what Foundation is doing. For more information about the
scrolling messages, see 3.1.4 Scrolling Messages.

Foundation User Guide
May 2012 Page 36
4.2 Utility Events
Utility events are signals sent from your energy utility to Foundation. Your energy utility typically uses
events to inform you about higher energy prices, or to reduce the load on the electricity grid. These
events are referred to as energy events and price conservation events. It is possible for both an energy
event and a price conservation event to occur simultaneously.
An energy event is a signal that your utility sends when it needs to reduce energy consumption. It tells
Foundation to adjust the target temperature or the amount of time that your heating and cooling
equipment runs. The signal causes Foundation to reduce your energy consumption.
A price conservation event occurs when your thermostat responds to price increases by adjusting the
temperature based on the Conservation Settings.
For more information, see 4.5 Conservation Settings.

Foundation User Guide
May 2012 Page 37
4.2.1 Energy Events
During an energy event, your utility sends a signal to Foundation. The signal causes the thermostat to
adjust the target temperature or the amount of time that your equipment runs. This reduces the
amount of energy that your heating or air conditioning system uses.
Each energy event has a start and an end time, as well as a target temperature, a temperature offset, or
a duty cycle. A temperature offset is a temperature adjustment in degrees above (for cool mode) or
below (for heat mode) the programmed temperature. A duty cycle is a temperature adjustment that is
shown as a percentage of the amount of time that the equipment is allowed to run.
When an energy event is in effect, a message displays on the home screen.
Energy events can be voluntary or mandatory.
4.2.1.1 Voluntary Energy Events
Participating in voluntary energy events saves you energy and money.
When there is a voluntary energy event, Foundation checks your Event Participation setting and
responds accordingly. If Foundation is set to Participate, it automatically adjusts for the event. If it is set
to Ignore, it disregards the event.
It is recommended that you set Foundation to participate in voluntary energy events. You will save more
money if you participate in all voluntary events. However, if you want to change the temperature, you
can create a temporary hold to override the event.
You will save more money when you participate in all events, and use a temporary hold only
when necessary, than when you ignore all events.
For information about creating a temporary hold, see 3.2 Change the Current Temperature Temporarily
or 3.6.2 Temporary Temperature Holds.
4.2.1.2 Mandatory Energy Events
Your utility may also send mandatory energy events, and Foundation cannot ignore these events.

Foundation User Guide
May 2012 Page 38
4.2.2 Blue Utility Event LED
Foundation has four light-emitting diodes (LED) that signal events from your utility. Each LED illuminates
for the duration of the corresponding event.
The Blue LED indicates that an energy saving or price conservation
event is in effect and has triggered the thermostat to adjust the
temperature. On the Thermostat home screen, Foundation
displays an energy event or price conservation message under the
temperature. The screen displays a message under the current
temperature. During mandatory events, you will not be able to
adjust the temperature until the event ends. If you set Event
Participation to Participate, your ability to adjust the temperature
may be restricted until the event ends. If you set Event
Participation to Ignore All, the LED does not illuminate when your
utility sends a voluntary event. For more information about Event
Participation, see 4.7.1 Event Participation.

Foundation User Guide
May 2012 Page 39
4.2.3 Price Conservation Events
Foundation supports price-driven peak load reduction programs. For example, some utilities use time-
of-use or peak pricing, where prices vary according to the time of day and the demand for energy.
The current price of energy can trigger a price conservation event. During a price conservation event,
the thermostat responds according to the Conservation Settings, and adjusts the temperature for the
duration of the event. You can set the Conservation Settings to determine how Foundation responds to
dynamic pricing programs from your utility.
For more information about Conservation Settings, see 4.5 Conservation Settings.
Price conservation events are always voluntary. You can set a temporary hold during a price
conservation event. If you do set a hold, the price conservation is suspended for the duration of the
hold.
When a price conservation event is in effect, a message displays on the home screen.

Foundation User Guide
May 2012 Page 40
4.2.4 LED Pricing Indicators
Foundation has four light-emitting diodes (LED) that signal events from your utility. Each LED illuminates
for the duration of the corresponding event.
Your utility can send price information events during periods of peak demand. The pricing LEDs
illuminate as the price increases. They enable you to see at-a-glance whether a peak pricing period is in
effect. The pricing LEDs use the lowest price that was received from your utility today or yesterday. The
prices that you enter manually do not cause the pricing LEDs to illuminate.
The yellow, orange, and red LEDs illuminate as the price of energy increases during a price information
event:
Yellow ($$): Indicates an energy price increase of 1.5 to up to 2.5
times the lowest price.
Orange ($$$): Indicates an energy price increase of 2.5 to up to
6.0 times the lowest price.
Red ($$$$): Indicates an energy price increase of 6.0 times the
lowest price (or more).
To save electricity costs, avoid using your clothes dryer, washing machine, or dishwasher
when the pricing LEDs are illuminated. Run these appliances, which consume a lot of
electricity, when the price is lower.

4.5 Conservation Settings
During pricing events, Foundation uses your Conservation Settings to determine how to adjust the
temperature. It can adjust the temperature by up to 9°F (5°C). Foundation either adjusts the
temperature to a nominal pricing rate, or keeps the temperature constant at the higher price level.
Note: Not all utilities provide pricing information over the communications link.
Use the Conservation Settings to prioritize either comfort or savings. The Conservation Settings screen
uses two bars to show the balance between comfort and savings. Each bar indicates the comfort and
savings levels. The two bars are linked, so that as one bar increases, the other bar decreases.
If your home is uncomfortable during price events and you frequently set a temporary
hold, try increasing the comfort setting by one level.
Conservation Setting
