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.
