Siemens 550-662B RTS Occupancy Override Thermistor

Siemens 550-662B RTS is a wireless room temperature sensor with occupancy override, housed in a white enclosure. It uses an onboard thermistor to measure ambient temperature and transmits readings to compatible Siemens RTS controllers over a wireless link, enabling responsive HVAC setpoint control in spaces like offices, classrooms, and conference areas without the need for wired sensors or extensive cabling. The occupancy override feature allows operators to temporarily adjust the room’s status within the RTS network, ensuring comfort when spaces are occupied while supporting energy-saving strategies during vacancy. Within Siemens’ RTS family, color options are indicated by catalog suffixes, and 550-662B is specified for White, aligning with standard product labeling.
