Communicating Thermostats

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.
