The new Honeywell Home T10+ Smart Thermostat Kits with RedLINK 3.0 offer additional control over three types of indoor air quality (IAQ) equipment simultaneously. Resideo's proprietary RedLINK 3.0 technology and Equipment Interface Module (EIM) enables simple set up and a customizable solution for each customer from a single device. The kits include, or can work with various accessories, such as the following: Honeywell Home T10+ Smart Thermostat; EIM; Wireless Smart Room Sensor which extends the reach of the thermostat beyond one hallway to detect temperature, humidity and occupancy in rooms, and automatically adjusts the smart thermostat based on preferences and schedule; Wireless Outdoor Sensor, which provides real-time, outdoor temperature and humidity readings to help balance IAQ inside the home; Return and Supply Air Sensor offers real-time temperature readings in ductwork for equipment protection; and Floor/Slab Sensor monitors the floor temperature for radiant, in-floor heating applications (sensor not included in the kits).
