The front cover is opened with a tool pressing both pressure closures located at
both edges of the cover (see Fig.5). For safety reasons, cables must be retained
using the support provided (see Fig.6).
In the case of an installation where cabling is outdoors, it must be installed inside a
cable ducting system with IP4X protection degree classified as "cable ducting with
access cover that can only be opened with a tool" according to UNE-EN 50.085-1:
Cable trunking systems and cabling ducting systems for electrical installations-

Pairing
See the instructions of the NARAH 160 RT energy recovery unit for the steps to
follow for pairing.
The 2-minute pairing window begins when the previously mentioned energy re-
covery unit is powered on. The AIRSENS RF.2 transmitter may remain powered at
all times to be paired. Once the pairing window has ended, pressing the S2 button
on the AIRSENS RF.2 (see Fig. 1) triggers 5 flashes on the LED D17 if the sensor is
within RF range and paired with the receiver.
If there is no response when pressing the button, it indicates that the device is out
of range or not paired.
