Configurable BACnet thermostats: AeroStat 200, 500 and 500 Touch
AeroStat
Thermostats that speak BACnet natively.
AeroStat configurable wall controllers bring rooftop units, heat pumps, fan coils and air handlers onto the BACnet MS/TP trunk, with up to 15 I/O and optional radar occupancy, NDIR CO₂ and Wi-Fi.
Key features
- BACnet MS/TP on every model; BACnet/IP over Wi-Fi on W models
- AeroStat 200: 2 UI, 1 AO, 4 BO · AeroStat 500: 5 UI, 3 AO, 7 BO
- Temperature and humidity sensing; optional radar occupancy and NDIR CO₂
- Color display; full-color capacitive touchscreen on the 500 Touch
- Configurable for RTU, heat pump, fan coil and AHU applications
