Honeywell Home C7189R2002-2-U T10 RedLINK Indoor Room Sensor - 2 Pack

Honeywell Home C7189R2002-2/U T10 RedLINK Indoor Room Sensor

The Honeywell Home C7189R2002-2/U T10 RedLINK Indoor Room Sensor provides wireless temperature, humidity, and motion sensing for compatible Honeywell Home T10 thermostats. Available in single-unit and 2-pack configurations, these sensors help homeowners monitor conditions in individual rooms and support more consistent temperature management throughout residential heating and cooling systems.

Designed for residential climate control, the Honeywell Home T10 RedLINK Room Sensor provides localized environmental monitoring beyond the thermostat's primary installation location. Temperature differences between bedrooms, living rooms, and other areas can affect overall comfort, especially in homes with multiple floors or varying sunlight exposure. By placing sensors in frequently occupied rooms, homeowners can provide their compatible thermostat with additional environmental information for more effective temperature management. The single-sensor option is suitable for monitoring one additional room, while the 2-pack allows monitoring in two separate locations. Both configurations provide a convenient way to expand compatible T10 thermostat installations without running communication cables between devices.

Each sensor communicates wirelessly using Honeywell Home RedLINK technology, which supports signal transmission through common residential building materials. Factory calibration eliminates the need for manual sensor calibration during installation. The wall-mounted design features a white housing that blends into residential interiors. Each unit operates using four AAA alkaline batteries and is designed for professional installation. Compatibility with the ThX3210WF T10 Pro Smart Thermostat with RedLINK helps ensure integration with supported Honeywell Home temperature management systems.

Key Features

• Available in Single and 2-Pack Configurations: Choose one sensor for an individual room or two sensors for monitoring environmental conditions in separate locations throughout the home.
• Temperature, Humidity, and Motion Detection: Monitors three environmental conditions to provide compatible T10 thermostats with additional room-specific information.
• RedLINK Wireless Communication: Uses Honeywell Home wireless communication technology to transmit sensor information without requiring dedicated communication wiring.
• Room-Specific Climate Monitoring: Helps identify temperature differences between rooms and supports more consistent residential comfort management.
• Factory-Calibrated Sensors: Arrives calibrated from the manufacturer, eliminating the need for additional field calibration.
• Flexible Wall-Mount Installation: Supports placement in selected indoor locations where localized temperature, humidity, and motion sensing is needed.
• Battery-Powered Operation: Each sensor operates using four AAA alkaline batteries for wireless installation flexibility.
• T10 Thermostat Compatibility: Designed for integration with compatible Honeywell Home T10 Pro Smart Thermostats equipped with RedLINK technology.

Available Sensor Pack Configurations

Single Sensor - 1 Piece

The single-unit configuration includes one Honeywell Home C7189R2002-2/U indoor room sensor. It is ideal for homeowners who want to monitor environmental conditions in one additional room using a compatible T10 thermostat.

This configuration provides an individual wireless sensor for applications such as bedrooms, home offices, living rooms, and other occupied spaces where localized temperature monitoring is beneficial. Each sensor provides temperature, humidity, and motion detection through RedLINK wireless communication.

• Pack Quantity: 1 Sensor
• Configuration: Single Unit
• AVL Gear SKU: HON-C7189R20022U-SINGLE
• Sensor Technology: Temperature, Humidity, and Motion
• Wireless Communication: RedLINK
• Battery Requirement: 4 AAA Alkaline Batteries

2-Pack - 2 Pieces

The 2-pack configuration provides two Honeywell Home C7189R2002-2/U indoor room sensors for monitoring separate areas within a compatible residential climate control system.

This option is suitable for homeowners who want environmental information from multiple rooms without purchasing individual sensors separately. Each sensor independently detects temperature, humidity, and motion and communicates wirelessly with a compatible T10 thermostat using RedLINK technology.

With two sensors, homeowners can extend room monitoring to additional areas, such as an upstairs bedroom and downstairs living room. Each sensor requires its own set of four AAA alkaline batteries and can be installed at a suitable indoor wall location.

• Pack Quantity: 2 Sensors
• Configuration: 2-Pack
• Sensor Technology: Temperature, Humidity, and Motion
• Wireless Communication: RedLINK
• Battery Requirement: 4 AAA Alkaline Batteries per Sensor
• Total Battery Requirement: 8 AAA Alkaline Batteries

Wireless Room Monitoring for T10 Thermostats

Temperature Monitoring

Each sensor detects the temperature within its installed location and communicates this information to a compatible thermostat. This allows the system to account for conditions in rooms that may differ from the area surrounding the main thermostat.

Localized temperature sensing is particularly useful in homes with multiple floors, rooms receiving direct sunlight, or spaces with different heating and cooling characteristics.

Humidity Detection

Integrated humidity sensing provides additional information about indoor environmental conditions. When connected to a compatible T10 thermostat, the sensor contributes room-level humidity measurements to the system's environmental monitoring capabilities.

Motion Sensing

Each room sensor includes motion detection capabilities that provide information about activity within the monitored space. This additional sensing function supports compatible thermostat features that use room activity information.

RedLINK Wireless Connectivity

Honeywell Home RedLINK technology enables wireless communication between the room sensors and compatible thermostats. The wireless system is designed to transmit information through common residential building materials, reducing the need for dedicated sensor communication wiring.

The sensors are factory calibrated and operate using standard AAA alkaline batteries. Their wireless design allows installation in selected indoor locations without requiring a wired data connection.

Applications and Installation

The Honeywell Home T10 RedLINK Indoor Room Sensor is intended for residential environments where monitoring individual room conditions can improve awareness of temperature differences throughout the home.

Typical applications include bedrooms, living rooms, home offices, upstairs spaces, and other interior areas where the main thermostat may not accurately represent localized environmental conditions.

Each sensor features a wall-mount configuration and is intended for professional installation. Before installation, verify thermostat compatibility and select indoor mounting locations appropriate for temperature, humidity, and motion detection.
