Siemens QAA2280.EWSC Room Temperature Sensor,
Siemens 2200/3200 Communicating Room Units connect
to the Terminal Equipment Controller via a single RJ-11
cable with RJ-11 plugs on either end for simple installation.
Data transferre quickly and reliably via a proven
Siemens protocol.
Units are available for temperature only, temperature
and humidity, or temperature and humidity and air quality.
Full HMI units enable occupant control of temperature
setpoint within limits configured by the building
management operator, while blank front units prevent
users from forcing the system into a potentially inefficient
operating strategy.
