What’s in the box?
ecobee Smart Thermostat Premium, ecobee Smart Sensor, Backplate, Wire labels, Screws & drywall plays plugs, power extender kit (for sysytems without a c-wire), trim plate, and quick start guide
Does the eco bee work with a ac unit and a humidistats?
ecobee Smart Thermostat Premium, Smart Thermostat Enhanced1, Smart Thermostat with voice control, ecobee4, and ecobee3 support most common HVAC accessories such as humidifiers, dehumidifiers, and ventilators.
Is this new model backwards compatible with the old style sensors?
The old sensors will work in the ecobee app but will always show “No Response” in homekit. Can’t even remove them from homekit. Very annoying.
Will this work a heat pump?
Yes, and a humidifier
Does this have a fan only mode where the fan can be turned on without heating or cooling?
Yes
does it also play Pandora app? It plays the Spotify app…?
Yes it’s does!
Does this light up red like an evil angry ai when alexa is turned off?
The microphone is replaced by a red symbol when the microphone is turned off. Nothing is red if you don’t connect it to Alexa in the first place. The microphone is too good. From the next room over the Alexa on the thermostat responds even when I have an echo Within 3 feet of where I’m sitting.
Do it come with geofence?
you can set a geo fence
Will this thermostat work for a split system?
Yes it will work
Can u use to drop in to another echo device?
Yes sure!
Can the screen be locked, to prevent annoying non-residing family members from changing the temps of they’re too cold?
YeS, you can lock it with a security code.
Can you turn off the radar occupancy sensor?
If you look in the app you can turn off the follow me function. From my understanding it turns off the sensor.
is this available in white?
Yes only in white
Will it display in Celsius?
yes
Will this ecobee work with the wiring of my Honeywell T6 th6220wf2006?
Yes
Is there a delay in turning on the AC after lowering the thermostat?
Yes, always. Usually it’s let’s than fine 5 minutes, mostly if you have a heat pump system.
Is it better than ecobee 4?
If a higher resolution display, stainless steel frame, and an air quality monitor are important to you, then yes.
Does it come with a 4wire to 5-wire adaptor to “ create” the C wire for power to the thermostat?”
Yes.
Does this support both a humidifier and a dehumidifier?
Yes it can do both and also ventilation.
How is this version different from the ecobee 4?
It does accept drop in requests, but doesn’t permit you to make a drop in to other echos on your network. The work around is to just make an announcement, and have the person you’re wishing to speak with in the mansion drop in to your thermostat.

Heat
An orange heat icon indicates that your thermostat is calling for heat. A white heat icon indicates that your system is in heat or auto mode but is not currently calling for heat.
Cool
A blue cool icon indicates that your thermostat is calling for cool. A white cool icon indicates that your system is in cool or auto mode but is not currently calling for cool.
Fan
A fan icon indicates that your thermostat is calling for the fan to run.
Auto
If both heat and cool icons are shown, your system is in Auto mode, meaning your ecobee3 will call for heat or cool as required.
The System menu controls the basic operation of the different components in your HVAC system, including the heat/cool mode, fan operation, and the operation of accessories like humidifiers, dehumidifiers, and ventilators.
HVAC System
The HVAC System settings depend on the type of system you have. Depending on your system, one or more the following options are shown:
On Thermostat and Mobile:
Select Main Menu > System > HVAC System
On Web:
Select System tile > HVAC
The Fan menu displays the current furnace fan setting. Depending on your system, one or more of the following options are shown:

The Ventilator/HRV/ERV menu configures the operation of a ventilator, a Heat Recovery Ventilator (HRV) or an Energy Recovery Ventilator (ERV), if installed:
Ventilation devices are important to maintain indoor air quality and, depending on where you live, this might be regulated. The amount of indoor air required to maintain sufficient indoor air quality depends on how big your house is, how many people live there, and the capacity of your ventilation device. You should consult with a local contractor who can guide you on how often you should be running your ventilation device.
For devices configured as ventilators (i.e. not HRVs or ERVs) you can enable a feature called “free cooling” on your ecobee3. When the outdoor temperatures are cooler than indoors and your system is calling for cool, your ecobee3 will turn on your ventilator to bring in outdoor air instead of running your air conditioner. To configure free cooling options, see page 26.
On Thermostat and Mobile:
On Web:
Your ecobee3 supports wireless remote sensors that detect motion and temperature in different rooms (one was included with your thermostat). Your ecobee3 also has a built-in motion sensor. With these sensors, you can optimize the operation of your thermostat to ensure comfort in the rooms and times that matter most.
For information about installing new sensors, see the ecobee Installation Guide, or the documentation included with the sensor itself.
Smart Home/Away applies all the sensors in your network – including the sensors built-in your thermostat. It works by following your schedule unless any sensor in your network is in conflict with your schedule. In other words, if your ecobee3 senses that you are home during a scheduled Away period, or away during a scheduled Home period, it will automatically override your schedule by placing you in Smart Home/Away mode to maximize comfort (Smart Home) and savings (Smart Away).
On Thermostat:
Follow Me is a feature that applies to a selected group of the sensors in your network (including the sensor built-in your thermostat). It works by looking for motion triggered by any of the selected sensors. If motion is detected, the temperature reading from that sensor will be used by your ecobee3 to decide when to operate your heating or cooling system. This ensures that you are comfortable in the rooms that you are occupying. If more than one sensor detects motion, the average of these sensors will be used. Your ecobee3 makes changes gradually when many sensors are detecting motion to make sure there are no sudden or large changes for your heating and cooling system to deal with.
When Follow Me is disabled, your ecobee3 will continuously use the average temperature readings from all the sensors that you’ve selected as the desired temperature to control your ecobee3. For example, suppose you have a room in your house that is far from your thermostat and you want this room to be at the thermostat’s set temperature, regardless if motion is occurring. In this case, set Follow Me to Disable and only select this room. Your ecobee3 will now only use the temperature in this room to decide when to operate your heating or cooling system.
On Thermostat:
You can configure your ecobee3 to fit your schedule and comfort needs while maximizing your energy savings.
Your ecobee3 organizes your temperature and fan settings into different Comfort Settings. These settings are used in the Schedule, Smart Home and Quick Changes menus
By default, your ecobee3 includes three configurable Comfort Settings:
Note: You can create new Comfort Settings (or remove them) from the Web Portal.
On Thermostat and Mobile:

To delete a Comfort Setting:
Your heating and cooling needs change depending on the time of day, day of the week, as well as when you are home or away. For example, if there’s no one in the house during the workday you might want to let the temperature go up in the summer, to reduce energy used by the air conditioning system, and down in the winter, to reduce heating energy.
The ecobee3 adapts to how your home and heating and cooling equipment perform. Intelligent algorithms combine weather data, your equipment run times and occupancy schedules to optimize performance and maximize energy savings. This means you can be comfortable when you are home and save money when you are not.
On Thermostat and Mobile:
Hint: You can copy the entire schedule from one day to another day (for example, if all your week days follow the same schedule). Display the first day, touch the copy button, select which days to apply the changes to, and touch Save.

Your ecobee3’s Vacation feature helps you conserve energy while you are away for extended periods of time. It also ensures your home is comfortable when you return.
A vacation event has a start date and time, as well as an end date and time. You can enter any number of vacations, as long as each has a unique start time.
The Vacation feature overrides your programmed schedule – you can leave your Schedule settings as-is when you go away for a special or unscheduled trip.
On Thermostat and Mobile:
The vacation event is now set. You can adjust it at any time by selecting it from the Vacation menu. To delete a vacation event:
1. Select Main Menu > Vacation 2. Select the vacation you want to delete.

Enabling this option allows the user to select auto change-over as a system mode.
On Thermostat:
The minimum difference between the heat mode set temperature and the cool mode set temperature when the system mode is in auto change-over. The delta is adjustable from 2 to 10 °F (1.1 to 5.5 °C). The default value is 5 °F (2.8 °C).
On Thermostat:
This enforces a minimum time that the compressor must be off between cycles. This ensures the compressor does not short cycle (which could negatively affect the operating life of the system). This time is adjustable from 240–900 seconds.
On Thermostat:
Enforces a minimum outside air temperature at which the compressor will be disabled. It prevents the compressor from running when the outdoor temperature is too low, thus resulting in damage to the compressor. If the compressor min outdoor temp is being enforced, auxiliary heat will be used to reach setpoint. The temperature range is adjustable from 0 to 65 °F (–17.8 to 18.3 °C) or can be completely disabled. This feature is typically used for air-to-air source heat pumps (35 °F min outdoor temp by default) and is disabled (by default) for geothermal heat pumps.
On Thermostat:
Note: You need an Internet connection for this feature to operate properly.
Uses the air conditioning to reduce the humidity by cooling beyond the current set point by the configured amount. Note that cooling is still determined by the set point, and the system will not resume cooling until the temperature rises above the current set point. For example, if your cooling set point is 75 F, and this value is set to 2 F, it will allow the AC to overcool to 73 F if the humidity set point has not been met.
On Thermostat:
Configures the maximum outdoor temperature above which the auxiliary heat will not be engaged. The temperature is adjustable from 0 to 80 °F (26.5 °C) in increments of 0.5°F (0.3°C). The default value is 70°F (21°C).
27
On Thermostat:
The minimum difference between the current temperature and set temperature before the system calls for heat. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. The temperature range is adjustable from 0 to 3 °F (0 to 1.7 °C) in 0.5°F (0.3°C) increments.
On Thermostat:
The amount of time the fan will run after the heat set point has been reached and the call for heat has been turned off. Running the fan for a period of time allows for any heated air left in the ducts to circulate throughout the home. The time is adjustable from 0 to 900 seconds. The default value is 30 seconds.
On Thermostat:
1. Select Main Menu > Settings > Installation Settings > Thresholds > Heat Dissipation Time. 2. Configure the settings as required.
Sets the minimum equipment run time in heat mode: 1 to 20 min (default is 5 min).
