Lennox 22V25 Smart Room Sensor

The Lennox 22V25 Smart Room Sensor is a critical component for contractors looking to optimize environmental control within a Lennox S40 Smart Thermostat ecosystem. Leveraging a Bluetooth Low Energy (BLE) Mesh network, this sensor provides precise temperature and humidity monitoring back to the primary interface, enabling room averaging and localized comfort management. The integrated occupancy sensor allows the system to dynamically adjust setpoints based on real-time room usage, enhancing overall system efficiency. Designed for rapid deployment, the unit is wireless and supports both wall-mounting and standalone placement with the included bracket. Note that the 22V25 is specifically engineered for the S40 platform and is not compatible with iHarmony zoning systems or older Lennox thermostats. While it facilitates superior air balancing data, it is not a substitute for proper duct design or equipment sizing. Up to six sensors can be paired to a single S40 hub to eliminate hot or cold spots in residential applications.

Key Benefits for HVAC Professionals

• Advanced Precise Temperature & Humidity Control: Delivers high-accuracy data via BLE Mesh to the Lennox S40 for real-time load adjustment.
• Integrated Occupancy Detection: Enables energy-saving logic by identifying active rooms and adjusting airflow/temperature setpoints accordingly.
• Scalable System Architecture: Supports up to 6 remote sensors per thermostat, allowing for comprehensive room averaging across multiple zones.
• Simplified Installation: Battery-powered and wireless design eliminates the need for pulling new thermostat wire through finished walls.
• Enhanced Signal Integrity: Compatible with optional wireless extenders to maintain connectivity in large-scale residential floor plans or high-interference environments.

Common Questions

Is the Lennox 22V25 compatible with the iHarmony Zoning System?
No, this sensor is designed exclusively for the S40 Smart Thermostat and does not integrate with the iHarmony Smart Zoning System hardware.

Can I use this sensor to fix airflow issues in a specific room?
While the Lennox 22V25 provides accurate data for temperature and humidity control, it cannot rectify mechanical issues such as undersized ductwork or improper equipment capacity.

How many sensors can be added to one S40 thermostat?
A single Lennox S40 Smart Thermostat can support a maximum of six Smart Room Sensors for data averaging and occupancy tracking.
