Description
Deliver precision multi-room comfort control and smarter zoning performance with the Honeywell Home RedLINK™ 3.0 Indoor Sensors (2-Pack), model C7189R3010-2 — professional-grade wireless room sensors engineered for commercial light and residential HVAC installations using Honeywell Home ElitePRO and T10+ Pro smart thermostats. Designed for HVAC contractors, system integrators, and building service professionals, this 2-pack provides the remote sensing intelligence needed to optimize comfort, reduce hot and cold spots, and maintain accurate temperature averaging across multiple zones or rooms.
Each sensor measures indoor temperature, relative humidity, and motion, transmitting wirelessly over Honeywell’s proven RedLINK™ 3.0 protocol with a robust 200-foot wireless range that penetrates most common building materials — including drywall, wood framing, and standard interior walls. This eliminates the cost, labor, and aesthetic challenges of running sensor wire through finished spaces, making the C7189R3010 an ideal solution for retrofit projects, historic buildings, open-ceiling commercial environments, and whole-home comfort upgrades.
The compact 2.6″ wall-mounted design blends into residential and light commercial interiors, while the simple pairing process allows HVAC technicians to commission sensors quickly during installation — reducing labor hours and callback risk. By sensing motion in addition to temperature and humidity, these sensors enable ElitePRO and T10+ Pro thermostats to prioritize occupied rooms, automatically adjusting setpoints based on where people actually are. This smart-response capability improves occupant comfort, minimizes wasted runtime on unoccupied zones, and supports measurable energy savings — a key selling point for contractors offering premium comfort solutions and efficiency upgrades.
Powered by 2 AAA alkaline batteries per sensor (4 AAA batteries included) and backed by a 5-year limited warranty, the C7189R3010-2 comes complete with mounting hardware for fast, no-fuss installation. Sensor compatibility is limited to ElitePRO S1200, S1100, and S1000 smart thermostats, as well as T10+ Pro smart thermostats with RedLINK 3.0 — contractors should verify thermostat model compatibility before specifying.
Features:
- RedLINK™ 3.0 Wireless Technology — Honeywell’s latest-generation wireless protocol delivers reliable, interference-resistant communication between sensor and thermostat, with signal penetration through most interior building materials.
- 200-Foot Wireless Range — Extended line-of-sight range supports multi-room, multi-zone, and whole-home installations without the cost and disruption of running low-voltage sensor wire.
- Three-in-One Sensing — Temperature, Humidity & Motion — Single sensor captures all three critical comfort inputs, enabling ElitePRO and T10+ Pro thermostats to deliver true occupancy-based comfort control and smart zoning logic.
- Motion-Based Priority Control — Thermostats automatically prioritize rooms with detected occupancy, reducing energy waste in unused spaces while maintaining comfort where it matters most.
- Precision Thermistor Sensor — Thermistor-based temperature sensing provides accurate, stable readings for reliable zone averaging and setpoint control.
- Fast Professional Installation — Quick pairing, included mounting hardware, and wall-mount form factor simplify commissioning on new construction and retrofit jobs — reducing billable install time.
- 2-Pack Value for Multi-Zone Jobs — Two sensors per pack make this ideal for bedroom/living room comfort averaging, multi-zone systems, or dual-area commercial setups; order multiple packs for whole-home or multi-zone commercial applications.
- Battery-Powered Flexibility — Operates on 2 AAA alkaline batteries per sensor (4 included) — no hardwire, no transformer, no service interruption during installation.
- 5-Year Limited Warranty — Professional-grade warranty coverage supports contractor confidence and long-term customer satisfaction.
- Discreet White Design — Clean 2.6″ square profile blends into residential and light commercial interiors without drawing attention.
Applications:
- Multi-zone residential and light commercial HVAC systems using Honeywell ElitePRO or T10+ Pro thermostats
- Whole-home comfort averaging across bedrooms, living areas, and upper/lower floors
- Retrofit projects where running sensor wire is cost-prohibitive or disruptive
- Custom homes, additions, and remodels requiring discreet, wireless comfort sensing
- Light commercial spaces — small offices, retail, restaurants, and professional suites — needing occupancy-aware control
- Property management and multi-family installations requiring scalable, wireless sensor solutions
- Comfort-upgrade add-on sales for existing ElitePRO/T10+ Pro thermostat installations
Note: It is not compatible with legacy RedLINK or RedLINK 2.0 systems, earlier VisionPRO/Prestige thermostats, or non-RedLINK platforms. Always verify thermostat model and firmware before specifying or installing.
