PERFORMING A
HARDWARE RESET
In rare circumstances, static electricity or power surges may interrupt
the operation of the Smart Thermostat or Equipment Interface, forc-
ing a hardware reset.
Resetting the Smart Thermostat
You can reset the Smart Thermostat by pressing the hardware reset
button, located through an opening in the top left corner of the
thermostat, as shown below.
Pressing the hardware reset button will not alter programming or
conguration options.
Resetting the Equipment Interface
To reset the Equipment Interface, rst remove the front cover to
expose the reset switch (see below).
Press the button to reset the relays to their inactive state. They will
turn on AFTER after the Smart Thermostat resends the required com-
mands. This may take up to two minutes.

Temperature Alerts
The Smart Thermostat can generate alerts when the temperature in
the home reaches a pre-programmed level. This protects the home
from damage due to freezing and/or excessive heat.
If you program this option, an alert will display on the thermostat. If the
user has an account on www.ecobee.com, an e-mail can be sent.
Low Temperature Alert - Select this item to set the temperature at
which the Smart Thermostat will generate a Low Temperature Alert.
The range can be:
O – no alert will be generated
Set temperature range of 40 – 60°F (4.5 – 15.5°C)
The default setting is 50°F (10°C).
High Temperature Alert - Select this item to set the temperature at
which the Smart Thermostat will generate a High Temperature Alert
message. The range can be:
O – no alert will be generated
Set temperature range of 90 – 100°F (32 – 35°C).
The default setting is O.

Installer Settings let you congure the settings related to the various
devices (such as a furnace, air conditioner, humidier, dehumidier, or
ventilator) that are connected to the Equipment Interface.
Installation Wizard
The Installation Wizard takes you step-by-step through a series of
choices regarding the heating and cooling equipment intended to
be connected to the Equipment Interface. Simply make the selec-
tions when prompted on the screen and press Next to advance to
the next screen. Once completed you will be shown a diagram of the
wiring connections as determined by the choices made during this
wizard. You can press Back to go back and make any changes. Once
you are satised with the setup press Done.
Equipment
In addition to the Installation Wizard, the equipment setting will
allow you to manually congure the various devices that are
connected to the Equipment Interface.
Heat Pump
Enables and congures the system for a heat pump, for either 1
or 2 stages.
O/B Energize on Cool if Yes, the reversing valve output (O/B terminal)
will activate when there is a call for cooling. If you select NO, the relay
will energize when there is call for heat.
Furnace

LED O Power is disconnected or has dropped below 9V.
System
This LED monitors the operation of the Equipment Interface and
the connection between the W and Y terminals to their respective
connections on the heating and cooling control board.
LED On There is a fault with the Equipment Interface or the
wiring to the heating or cooling equipment.
LED O The equipment is operational and there is connection
to the heat and/or cool relay outputs (W or Y).
Line
This LED monitors the power supplied to the Smart Thermostat from
the Equipment Interface.
LED ON The voltage at the +12V and GND terminal has

This LED monitors the communications between the Smart Thermostat
and the Equipment Interface (i.e., the D+ and D- terminals).
LED On The Equipment Interface and Smart Thermostat are
not communicating to each other.
LED O The two devices are communicating properly.
18
Connecting power
Once you’ve completed the wiring of the Smart Thermostat
and Equipment Interface, you can apply power to the Equipment
Interface and restore power to the heating and air conditioning

Use drywall plugs or other screw anchors (not included) to
ensure the Equipment Interface can be mounted securely on the
intended surface.
Fasten the backplate to the wall using the appropriate screws
(not included).
Wiring the Equipment Interface
To wire the Equipment Interface:
Disconnect the power to the heating and air conditioning equipment.
Disconnect the wires going to the existing thermostat.
Using the wiring diagrams below, connect the heating or air
conditioning equipment to the Equipment Interface.
Do not apply power until you have installed and connected the
Smart Thermostat. (see instructions below)
Do not install the front cover on the Equipment Interface at this point.

Connecting the Smart Thermostat to
the Equipment Interface
Only four wires are required to connect the Smart Thermostat to the
Equipment Interface. If you are replacing a thermostat, you can use
the existing wiring.
Note: Ensure that any unused wires do not have exposed bare copper.
Follow these steps to connect the thermostat to the
Equipment Interface:
Connect the wires between the Smart Thermostat and
Equipment Interface as shown below.
Once wiring is complete, insert the coin cell battery (included) into
the holder. Ensure the (+) side of the battery is facing up.
Attach the front cover of the Smart Thermostat to the backplate.
Ensure the four pins on the circuit board mate with the terminal
block on the backplate as shown below.
If you haven’t already done so, replace the front cover of the
Equipment Interface.
16
Using the backplate as a template, mark the location of the mount-
ing holes on the wall as shown below.
Move the backplate out of the way and make holes where indicated in
step 3. The mounting holes can accommodate a #6 pan-head screw.
Use drywall plugs or other screw anchors (not included) to ensure
that the thermostat can be mounted securely to the wall.
Fasten the backplate to the wall using the appropriate screws

Installing the Smart Thermostat
The ideal location for the thermostat is approximately ve feet
above oor level in the main living area.
Do not install the thermostat:
Close to sources of heat such as incandescent lights,
television sets, or heating/cooling registers.
In direct sunlight.
On exterior, non-insulated or poorly insulated walls.
In the kitchen or other areas of potentially high heat
and/or humidity.
In an area that could restrict air ow, e.g., behind a door.
To install the Smart Thermostat:
Remove the front cover of the Smart Thermostat, insert a at-head
screwdriver into one of the slots as shown below and gently twist
the screwdriver.
Place the Smart Thermostat backplate on the wall. Make sure that any
existing wires can be inserted through the opening for the wiring.
