1 Functional description
The Relay radio humidity and temperature sensor RelAir ICS can be integrated into an
existing wireless M-Bus OMS network and provides reliable temperature measurement data.
The room temperature and humidity can be monitored wirelessly at any time. A further
advantage of the room climate sensor is its easy assembly. The configuration can be done
local via dip switches. The battery life is up to 10 years for this device depending on the
transmit interval. The two AA batteries are easily replaceable and have a reverse polarity
protection. The following graphic shows an application of the sensor:
