75F 7X-SN-K3X-X Remote Temperature Humidity Sensor

The 75F 7X-SN-K3X-X Smart Node with Remote Temperature & Humidity Sensor is a building‑automation module that brings localized temperature and humidity data into the 75F control ecosystem, enabling zone‑level climate decisions. It connects to 75F controllers through the Smart Node sensor bus using a 3‑core Molex connector for power and communication, ensuring out‑of‑the‑box integration with the Facilisight applications. The remote sensor measures temperature from 0 to 122°F (−17 to 50°C) and humidity from 0 to 100% RH, with typical temperature accuracy around ±1°F and humidity accuracy around ±2% RH, providing reliable data to drive HVAC adjustments. The unit is powered by 24 VAC, and its sensor‑bus architecture aligns with other 75F sensors to aggregate readings from multiple remote points for cohesive system performance. As part of the 75F Sensor Family, this model uses the same remote sensing approach, extending coverage to areas where central sensing isn’t practical and helping balance comfort and energy use across rooms and zones.
