ecobee3 Smarter Wi-Fi Thermostat with Remote Sensor, 2nd Generation User Manual

1. Introduction

The ecobee3 Smarter Wi-Fi Thermostat with Remote Sensor is designed to provide intelligent climate control for your home. Unlike traditional thermostats that measure temperature in a single location, the ecobee3 utilizes remote sensors to detect temperature and occupancy in multiple rooms, ensuring comfort where it matters most and optimizing energy savings when you are away. This manual provides detailed instructions for installation, operation, and maintenance of your ecobee3 thermostat system.

2. Product Overview

The ecobee3 system consists of the main thermostat unit and one or more remote sensors. The thermostat features a touchscreen display for direct control and information display, while the remote sensors extend temperature and occupancy detection to other areas of your home. This integrated approach allows for more precise and efficient climate management.

2.1 Key Components

• ecobee3 Thermostat: The central control unit with a touchscreen interface.
• Remote Sensor: Detects temperature and occupancy in specific rooms, communicating wirelessly with the thermostat.
• Power Extender Kit (PEK): May be required for systems without a common wire (C-wire).

3. Installation

Proper installation is crucial for the optimal performance of your ecobee3 thermostat. If you are unsure about any step, it is recommended to consult a qualified HVAC professional.

3.1 Pre-Installation Checklist

• Power Off: Before beginning, turn off power to your heating and cooling system at the circuit breaker.
• Compatibility: Ensure your HVAC system is compatible with the ecobee3. Most 24VAC systems are compatible.
• Tools: Gather necessary tools such as a screwdriver, drill, and wire strippers.

3.2 Removing Your Old Thermostat

1. Turn off power to your HVAC system.
2. Carefully remove the cover of your existing thermostat.
3. Important: Take a clear picture of the wiring connections before disconnecting any wires. This will serve as a reference during ecobee3 installation.
4. Label each wire with the provided labels or by noting the terminal designation.
5. Disconnect the wires and remove the old thermostat's backplate from the wall.

3.3 Installing the ecobee3 Thermostat

1. Mount the ecobee3 backplate to the wall using the provided screws and anchors.
2. Connect the labeled wires to the corresponding terminals on the ecobee3 backplate. If a C-wire is not present, follow the instructions for installing the Power Extender Kit (PEK).
3. Gently push any excess wire back into the wall opening.
4. Align the ecobee3 thermostat display with the backplate and push it firmly until it clicks into place.

3.4 Initial Setup and Wi-Fi Connection

1. Restore power to your HVAC system at the circuit breaker.
2. The ecobee3 will power on and guide you through the initial setup process on its touchscreen. This includes configuring your HVAC system type and connecting to your home's Wi-Fi network.
3. Download the ecobee app on your smartphone or tablet (available for iOS and Android) to complete registration and gain remote control capabilities.

4. Operating Instructions

The ecobee3 thermostat offers intuitive control through its touchscreen and the ecobee mobile application.

4.1 Thermostat Display and Controls

The main screen displays the current indoor temperature, desired setpoint, and system mode. You can adjust the temperature by sliding your finger up or down on the screen.

4.2 System Modes

The ecobee3 supports various system modes:

• Heat: Activates your heating system to reach the setpoint.
• Cool: Activates your cooling system to reach the setpoint.
• Auto: Automatically switches between heating and cooling to maintain the desired temperature range.
• Off: Turns off your heating and cooling system.

4.3 Remote Sensors

Remote sensors detect temperature and occupancy in different rooms. The thermostat uses data from occupied sensors to optimize comfort. Place sensors in frequently used rooms to maximize their effectiveness. The connection between the remote sensor and the thermostat can be affected by physical obstructions like closed doors, which may temporarily break the link.

4.4 Scheduling and Smart Features

The ecobee3 allows you to create custom schedules for heating and cooling based on your daily routine. Its smart features include:

• Home & Away: Automatically adjusts temperature settings when you leave or return home based on occupancy detection.
• Follow Me: Prioritizes comfort in occupied rooms by averaging temperatures from active sensors.
• Smart Recovery: Learns how long it takes to heat or cool your home and starts early to reach your desired temperature at the scheduled time.

5. Key Features

• Works with Amazon Alexa for voice control (Alexa device sold separately).
• Intuitively understands when to activate heating or cooling based on your home's energy profile, external weather conditions, and other data points.
• Senses whether anyone is home and which rooms are occupied, providing comfort when present and saving energy when away.
• Advanced Learning Algorithms for optimized performance.
• Smart Home Integration with Apple HomeKit, SmartThings, and Vera.
• Wi-Fi Connectivity for remote access and control.
• Touchscreen Display for easy interaction.
• Remote Control via dedicated mobile applications.

6. Maintenance

The ecobee3 thermostat requires minimal maintenance to ensure continued optimal performance.

• Cleaning: Gently wipe the touchscreen and the remote sensors with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Battery Replacement: The remote sensors use 1 CR2 battery (included). Replace batteries as indicated by the thermostat or app notifications.
• Software Updates: Ensure your ecobee3 is connected to Wi-Fi to receive automatic software updates, which provide new features and performance improvements.

7. Troubleshooting

If you encounter issues with your ecobee3 thermostat, refer to the following common solutions:

• No Power to Thermostat: Check the circuit breaker for your HVAC system. Ensure all wires are securely connected to the ecobee3 backplate. If a PEK was installed, verify its connections.
• Heating/Cooling Not Working: Verify the system mode (Heat, Cool, Auto) is correctly selected. Check wiring connections, especially the O/B valve setting during initial setup, as incorrect configuration can lead to improper heating/cooling.
• Remote Sensor Disconnected: Ensure the remote sensor is within range of the thermostat and its battery is not depleted. Physical obstructions like thick walls or closed doors can interfere with the wireless signal.
• Wi-Fi Connection Issues: Restart your home router and the ecobee3 thermostat. Re-enter your Wi-Fi credentials if necessary.
• Inaccurate Temperature Readings: Ensure sensors are not placed near heat sources, direct sunlight, or drafts.
