Safety Considerations
Read and follow manufacturer instructions carefully. Follow all local
electrical codes during installation. All wiring must conform to local and
national electrical codes. Improper wiring or installation may damage
Thermostat.
Recognize safety information. This is the safety-alert symbol
you see this symbol on the equipment and in the instruction manual, be
alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury or
death. WARNING signifies a hazard which could result in personal
injury or death. CAUTION is used to identify unsafe practices which
may result in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.
Introduction
The ecobee Smart Thermostat Pro with voice control, Powered by
Bryant and the ecobee3 lite Pro, Powered by Bryant provides your
customers with freedom and flexibility to manage their home
environment. These thermostats help homeowners conserve energy, save
money and reduce their environmental impact. They support a furnace
with AC and up to 2-stages of heat. For heat pumps (air to air or
Geothermal) they support up to four stages of heat (2-stage heat pump,
2-stage auxiliary heat) and two stages of cool. For these systems the
thermostats can control a single accessory, such as a humidifier,
dehumidifier, ventilator, HRV or ERV. Also, the thermostats can be
installed with the PEK if a C wire isn't present. Additionally, the
thermostats can control boilers with or without an AC. When connected
to a boiler, the thermostats support up to 2-stage of heat and 2-stages of
cool and a single accessory, such as a humidifier, dehumidifier,
ventilator, HRV or ERV. When used with a boiler they cannot be

installed with the PEK if a C wire isn't present, the C wire must come
from the air handler, not the boiler.

Before installing, modifying, or servicing system, main electrical
disconnect switch must be in the off position. There may be more than
1 disconnect switch. Lock out and tag switch with a suitable warning
label.
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Improper wiring or installation may damage the thermostat. Check to
make sure wiring is connect before proceeding with installation or
turning on unit.

Page 3: Wiring Diagrams
A common wire to power is needed to power the thermostat. Additional wires are shown as dotted lines for 2-stage equipment. Most Bryant 2 stage furnace equipment can be operated with a single stage thermostat using the algorithm in the furnace circuit board to engage 2nd stage. - Page 4 : Advanced Installation and Configuration Instructions Power Extender Kit (PEK) A200458 In the example above, the PEK is shown with wire labels. The Red wire goes to Rc and the White wire goes to W. However, the Green wire, which is labeled G in the drawing does not go to G.
- Page 5 For a traditional heat pump, Y1 is the compressor and O/B is the reversing valve. During the startup process, the O/B should be configured to act as an O terminal with Bryant equipment, since the equipment defaults to heating and needs the reversing valve to be energized on a cooling call. W1 is used for the auxiliary heat –...

- Page 7 : Advanced Installation and Configuration Instructions A boiler only system still needs a common. The best solution is to run a 3rd wire to the boiler and tie into the common. Many boilers will only have T-T terminals and not have a common terminal. In these cases, the common can be picked up directly from the transformer.
- Page 8 If the accessory terminals are not being used for a humidifier or whole house dehumidifier, then they may be used for the dehumidification feature integrated into Bryant FV fan coils and select variable speed furnaces. The ACC+ terminal will wire to the DH or DHUM terminal on the equipment in these applications.
- Page 9 A standard furnace with A/C or a fan coil with heat pump will only have a single transformer and so only Rc is connected. It is important to note that in these applications, Rc must be used instead of Rh like some Bryant thermostats. If the heating and cooling equipment have separate transformers, such as a boiler with a fan coil and A/C, then both Rc and Rh are connected.

The screens that follow will depend on the selection made here. Start-Up –> Dehum for Fan Coil or Furnace Initial Start-Up –>... - Page 11 Initial Start-Up –> Heat Pump A200472 Bryant heat pumps need the reversing valve (O terminal) to be energized on a cooling call, so On cool should be selected. Some other equipment manufacturers could energize the reversing valve on a heat call.
- Page 12 : Advanced Installation and Configuration Instructions A200473 Select Enable If the auxiliary heat source is electric resistance and it is desired to have heat pump and electric heat to run at the same time. The system will provide heat pump heating at lower stage and then turn on electric heat along with the heat pump at higher stages. If it is a “dual fuel system,” meaning the auxiliary heat is a fossil fuel furnace, including natural gas, propane, or oil, then select Disable.
- Page 13 : Advanced Installation and Configuration Instructions Initial Start-Up –> Furnace A200475 The fan should be controlled by the furnace for all current CBP and ICP furnaces. This allows the furnace to delay the fan on a W1 allowing the heat exchanger to warm-up before engaging airflow so the occupants do not get a blast of cold air.
- Page 14 : Advanced Installation and Configuration Instructions Installation Settings > Equipment > Humidifier > DeHum for Fan Coil or Furnace A200477 When this feature is wired and set up along with AC Overcool Max, it allows multiple modes of cooling operation, including temperature only demand, dehumidification demand, and both.
- Page 15 : Advanced Installation and Configuration Instructions Installation Settings > Thresholds > Reverse Staging A200479 The Compressor Staging and Heat Staging settings work the same. If Reverse Staging is enabled, then the installer must configure values for Stage 2 delta, which is the space temperature deviation required to engage second stage.
- Page 16 : Advanced Installation and Configuration Instructions A200481 ecobee has an Auxiliary Savings Optimization algorithm with settings that are in language that is supposed to be homeowner friendly. Essentially this setting determines how many degrees out of setpoint before auxiliary heat will be engaged. It starts at a half degree with Minimum, but up to 2.5 degrees if set on Maximum.
- Page 17 : Advanced Installation and Configuration Instructions A200484 If Manual staging is selected instead of Automatic, then 5 additional staging options for the Auxiliary heat need to be configured. Unlike straight cooling projects where Manual Staging is recommended be enabled so Reverse Staging could be utilized, the same recommendation is not made for heat pumps.
