Combination sensor inside and outside
- Unpack the combination sensors and attach them to the interior or exterior wall with the cable pointing downwards. The combination sensor is attached to the wall with a stainless countersunk screw.
- Push the sensor connection cable through the wall breakthrough/empty duct.
- Lay the sensor connection cable up to the AKE control unit.

The cable of the AKE FFT can be extended on site with LIYY 4x0.25 mm² cable:
- The extension must be protected from the weather.
- The maximum length of the complete cable is 30 m.
Do not lay the sensor connection cable together with 230 V power cables in a cable duct. This can lead to malfunctions in the communication between the sensor and the control circuit board.
