75F® Smart Stat

All-in-one commercial thermostat and humidistat with seven onboard sensors to manage indoor air quality.

Never Boring. Never Average.

The 75F Smart Stat is a modern all-in-one thermostat, humidistat and IAQ sensing station. It brings HVAC equipment online for secure remote management from any smartphone or connected device. Occupants can make temperature adjustments within predefined limits or adjust fan settings from either a radial touch-illuminated interface or the 75F Occupant App.

This device supports the WELL building standard for healthy buildings and tracks occupancy, temperature, VOC, derived CO2, humidity, light and sound measurements every 60 seconds for integration to built in AI and analytics.

Onboard IAQM for Maximal Productivity & Comfort

The 75F Smart Stat adheres to the WELL Building Standard metrics for indoor air quality without running wires or integrating data across multiple different sensor units. This real-time data visibility assures a more comfortable and productive indoor environment while achieving energy savings.

Personalized Zone Control, Right Out of the Box

The Smart Stat controls almost any existing HVAC equipment as a quick-install retrofit or new-build solution.

Improved Installation

With easy Bluetooth pairing and no programming required, installing a Smart Stat takes minutes. Machine learning from the 75F Cloud factors building position and load history, real-time sensor data, and outside weather forecasts to predictively manage building zones.

Secure Wireless Mesh Network

Unlike WiFi connected thermostats, Smart Stat uses 75F’s secure and proprietary encrypted 900Mhz mesh network for lightweight, best-path communications between devices and the Central Control Unit.

Web & Mobile Access

Facilisight gives owners and facility managers remote control, monitoring and analytics of IAQ Smart Stat data for building and equipment performance across multiple sites, floors and zones. The free 75F Occupant App includes mobile temperature and lighting control, plus geofencing and feedback tools.
