Engineering and Installation Guide

Wireless Integration: The TC320B-G utilizes wireless communication to link with building controllers. This simplifies deployment in historical or glass-walled buildings where invasive wiring is not feasible. Ensure the wireless gateway is within range to maintain an authoritative signal.
Power Connection: Although the communication is wireless, the thermostat requires a constant 24V power source. Connect the R and C terminals to a clean 24V transformer to ensure steady operation of the capacitive touch interface and LED backlight.
BACnet Configuration: Assign a unique Device Instance ID and MAC address through the setup menu. This ensures the TC320B-G is correctly identified by the building's head-end software for centralized monitoring and scheduling.
Calibration Expertise: For mission-critical environments, perform a temperature offset calibration during commissioning. This ensures the displayed value on the TC320B-G matches the actual ambient conditions with high-level accuracy.

Technical FAQ

Does the TC320B-G require a specific wireless hub?

Yes. To bridge the wireless data into a wired BACnet MS/TP or IP backbone, an authorized Honeywell wireless receiver/gateway is required. This gateway translates the wireless signals into standard BACnet objects for the BMS.

How does the capacitive touch screen handle industrial environments?

The capacitive touch technology used in the TC320B-G is designed for durability. Unlike resistive screens, it does not wear out over time, and the LED display provides high visibility even in dimly lit utility rooms or hallways.

Can the TC320B-G be used for both heating and cooling?

Absolutely. The thermostat supports multiple HVAC stages including heat pump, auxiliary heat, and multi-stage cooling. These parameters are fully configurable via the local interface or through the BACnet network objects.
