BAST-221C-BW2

The BAST-221C-BW2 wireless thermostat model is BACnet/IP connected using a wireless connection to a nearby Wi-Fi router/access point which supports IEEE 802.11b/g/n.

The respective maximum indoor range is 115 ft. for IEEE 802.11b, 125 ft. for IEEE 802.11g, and 225 ft. for IEEE 802.11n considering there are little to no substantial obstructions between the Wi-Fi router and the thermostats which is the case in most standard buildings. Some building materials rarely found in standard buildings can create obstructions which prevent Wi-Fi radios from communicating such as thick reinforced concrete (at least 200mm with or without metal reinforcement), thick masonry blocks and brick-faced walls, and metal obstructions such as shelving units or dense metal reinforcements. However, most widely used materials such as standard concrete or brick walls (100mm), lumber, plywood, and glass do not impose serious Wi-Fi radio barriers making Wi-Fi a convenient choice for many installations where wireless communication can be conveniently leveraged to avoid running wires.
