Communicating Thermostats

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 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.

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.
