TC300 THERMOSTATS
CONNECTED DEVICE FOR
COMMERCIAL BUILDINGS
TC300 thermostat models are advanced,
highly configurable devices providing building
automation connectivity well suited for
commercial building applications. Supported
equipment types include 2/4-Pipe FCU, 1H/1C
conventional, and 2H/1C heat pump plus water
source heat pump.
The TC300 models support BACnet MS/TP and
Modbus communications, while the TC320
models also support BACnet IP via Wi-Fi.
All models have intelligent control algorithms, scheduling, and an intuitive touchscreen interface. The B models support low
voltage power input, while the C models support line voltage power input. The TC320 variant also has Wi-Fi and Bluetooth
connectivity.
