Connect the sensor unit to the remote display unit by using the communication cable which is wired to the
sensor unit. Make sure the cable is run properly and attach it to the wall by using cable clips. Once it is
plugged in the remote display unit, the devices can communicate with each other.
There is also a potential-free contact (J) wired to sensor unit which can be used to turn on or off a fan, for
example, which is used for ventilation of the monitored room. When the red and white cables are
connected, the contact closes. When the white and blue cables are connected, the contact closes.

Connect the mains adaptor to the wall socket. Attach the elastic safety strip to the power plug by using
screws and wall plugs. The strip should sit so tight that the plug cannot be pulled out of the socket without
using mechanical tools. Once the mains adaptor is connected to the power source, the Sensor unit and
the remote display unit start monitoring.
Check the communication between both devices by using the “DIAG” function which is described in the
further course of this manual. If all four LEDs flash and the buzzer makes a sound the communication is
good and both devices show the same readings on their displays.
