Selecting System Operation Mode

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:

• Cool: Turn on the air conditioner when the current temperature rises above the set temperature.
• Heat: Turn on the heat when the current temperature drops below the set temperature.
• Auto: Activate the heating or cooling system as required to keep your home within the configured range of set temperatures.
• Aux: Only use the auxiliary or backup heat source to maintain the heat set point temperature. This option only appears if auxiliary heat is configured in the Equipment menu.
• Off: Turn the system off. When the system is off, only the current temperature will be displayed on the Home screen.

On Thermostat and Mobile: Select Main Menu > System > HVAC System

On Web: Select System tile > HVAC

Fan

The Fan menu displays the current furnace fan setting.

Depending on your system, one or more of the following options are shown:

• On: Force fan to run continuously, regardless of the scheduled programming. The fan will also run if the System Mode is Off.
• Auto: Enable fan when the system is actively heating or cooling your home, or to satisfy the Minimum Fan Runtime setting (page 12).

On Thermostat and Mobile:

Select Main Menu > Quick Changes > Fan

On Web:

Minimum Fan Runtime (Auto mode only)

When the fan is in Auto mode, ecobee3 operates it according to the Minimum Fan Runtime setting. You can adjust this setting from 0 to 55 minutes.

When your system is in heat or cool mode, the fan will always run for this minimum amount of time. A longer runtime improves air circulation and results in a more consistent temperature than with the Auto setting while being more cost-effective than the On setting.

Your ecobee3 will meet this minimum runtime over the hour while making sure it never runs for less than five minutes.

On Thermostat and Mobile:

1. Select Main Menu > System > Fan
2. Swipe left or right to adjust the value.

On Web:

1. Select System Tile > Fan
2. Swipe or drag left or right to adjust the value.

Adjusting Sensor Modes

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

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:

• 1. Select Main Menu > Sensors > Smart Home/Away
• 2. Touch Enable to have your sensor network and thermostat detect occupancy. To have your thermostat strictly follow your programmed schedule, touch Disable.

Follow Me

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 14 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:

• 1. Select Main Menu > Sensors > Follow Me
• 2. Enable or disable the Follow Me feature.
• 3. If enabled, select which sensors are affected by pressing on each checkbox.

Adjusting Comfort Settings

Setting Your Weekly Schedule

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.
