NOTICE
●Commission and setup the device prior to mounting.
●To power on the sensor module, connect it to a surface mount powered by
USB type C, PoE, or AC/DC 12...24 V.
Mounting location
●The devices are suitable for drywall mounting, conduit box mounting and surface mounting.
●Recommended height: 1.5 m (4 feet) above the floor. If the recommended height cannot be met, it should
not be lower than 0.9 m (3 feet).
●Do not mount the devices in recesses, shelves, behind curtains or doors, or above or near heat sources.
●Avoid direct solar radiation and drafts.
●Avoid unheated (uncooled) building area such as outside walls.
●Seal the conduit box or the installation tube if any, as air currents can affect sensor readings.
●Adhere to allowed ambient conditions.
●Devices should be mounted at least 5 m (16 feet) away from operable windows, air filters, and fresh air
diffusers.
●In areas where this is impossible, center your device between windows and place your monitor closer to air
return than air diffusers.

●With the inside (concave surface) facing you ensure that the mode selection switch points to 1 (LoRaWAN).
For configuration of BACnet, see Commissioning.
Preparing data connection
Set up your LoRaWAN gateway router prior to installation and on-boarding if LoRaWAN is used
●Unpack the contents of your surface mount kit and In-wall mount kit. If you plan to use LoRaWAN for data
connectivity, locate the LoRa gateway antenna provided in the surface mount kit and screw it onto the top of
the surface mount.
