AHR Expo 2026 Communicating Thermostats
Communicating Thermostats
The BASstat line of BACnet Communicating Thermostats feature BACnet functionality over MS/TP or Wi-Fi. Models exist for multi-staged heating/cooling of rooftop units (RTUs), compressor heat pumps, analog 4-pipe fan coils (FCUs), and single-mode unitary heating or cooling units. These devices can easily be supervised by a BACnet client.
The BACnet-compliant wired or wireless communicating thermostats ensure effortless integration into BACnet/IP (Wi-Fi) or BACnet MS/TP (EIA-485) networks. All units require 24 VAC/VDC powering from NEC Class 2 power sources. Output relays restricted to NEC Class 2 wiring. All models accommodate NTC 3k remote temperature sensor and voltage-free occupancy sensor. LCD display can be configured for °C or °F.
BAST-121 Single Mode Thermostats
BAST-121C Thermostats are suited for single or multi-stage heating only or cooling only binary or analog output control applications, such as unitary heating or cooling units. The thermostat can control one or two stages of heating, one or two stages of Direct Expansion (DX) cooling, or a single 0-10V control output for either modulated heating or cooling. Configurable and adaptive control algorithm applied to multi-stage on/off control saves energy and ensures seamless comfort for the occupants.
BAST-221 Multi-Stage Heating/Cooling Thermostats
BAST-221 Thermostats are suited for single or multi-stage heating, cooling and ventilation binary output control applications such as RTUs or AHUs. Configurable and adaptive control algorithm applied to multi-stage on/off control saves energy and ensures seamless comfort for the occupants.
BAST-321 Heat Pump Thermostats
BACnet Heat Pump Thermostats are suited for heating, cooling, and ventilation with binary output control for single and multi-stage heat pumps with or without 3rd stage auxiliary heat. An adaptive control algorithm applied to multi-stage on/off control saves energy and ensures comfort for the occupants.
BAST-421 Modulating Thermostats
BAST-421 Modulating Thermostats are suited for modulated heating, cooling, and ventilation with analog output control in 4-pipe applications such as fan coil units (FCU) or air handlers. Configurable and adaptive control algorithm applied to multi-stage on/off control saves energy and ensures seamless comfort for the occupants.
