DocumentDocumentTC300 THERMOSTATS CONNECTED DEVICE FOR COMMERCIAL BUILDINGS TC300 thermostat models are advanced, highly configurable devices providing building automation connectivity well-suited for indoor commercial building applications. These models offer flexible I/O options that will satisfy the needs of most 2-pipe or 4-pipe fan coil applications, 1H/1C conventional, and 2H/1C heat pump. Supported functions include dehumidification with reheat using an embedded humidity sensor, auxiliary heat functions, and a more rapid transitional 2-pipe system seasonal changeover. There are 6 thermostat models available TC300B-G, TC300C-G, TC321B-G, TC320B-G, TC320C-G and TC320C-N. The TC300 models support BACnet MS/TP and Modbus communications, while the TC320 and TC321 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 and TC321 models also have Wi-Fi and Bluetooth connectivity.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. · Limited by local law regulations, version for North America does not have region selection option. · To satisfy FCC&IC&CE RF exposure requirements, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. · Les antennes installées doivent être situées de facon à ce que la population ne puisse y être exposée à une distance de moin de 20 cm. Installer les antennes de facon à ce que le personnel ne puisse approcher à 20 cm ou moins de la position centrale de l' antenne. Region Selection (for Wi-Fi 2.4G device).
