BASstat Series BACnet Thermostats
Thermostats in the series are designed for BACnet/IP over Wi-Fi or MS/TP multi-stage rooftop units and analog 4-pipe fan coil units. 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.

Fan coil units are intended for 4-pipe systems and modulating 0-10V actuators.
BAST-121 Single Mode Thermostats
The BAST-121C is 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
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.
BAST-421 Modulating Thermostats
These 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.
