The Heatmiser Wireless Air Sensor can be used with the Touch V2, Edge and Neo System (NeoStat and NeoAir) and can be used as a single temperature sensor or as part of a group when an averaged temperature reading is required. The Wireless Air Sensor pairs directly with the Touch v2 and Edge whereas with the Neo System the Wireless Air Sensor is paired to the neoHub Gen 2 and then linked to the appropriate zone.
