Communicating Thermostats BACnet-Compliant Wired or Wireless

BACnet Communicating Thermostat for Multi-Stage Heating/Cooling/Ventilation

BAST-221 Thermostats are suited for single or multi-stage heating, cooling, and ventilation binary output control applications such as RTUs or AHUs. A configurable control algorithm allows adaptability to the specific application. This adaptive control algorithm applied to multi-stage on/off control saves energy and ensures seamless comfort for the occupants. A built-in relative humidity sensor (in 221CH models) allows the thermostat to display relative humidity on the screen as well as serve it as a BACnet object, dew point calculation is also served as a BACnet object (no control action is taken based on humidity).

BACnet Communicating Thermostat for Single and Multi-stage Heat Pumps

BAST-321 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. Three sensing options are available: built in temperature sensor, input for a remote temperature sensor, or temperature override network command from Building Automation System.

BACnet Communicating Thermostat for Modulating Fan Coil Operation

BAST-421 Modulating Thermostats are suited for modulated heating, cooling, and ventilation with analog output control in 4-pipe applications such as FCUs or air handlers. A configurable control algorithm allows adaptability to the specific application. This adaptive algorithm applied to the modulated valve control saves energy and ensures comfort for the occupants.
