General installation requirements The ComfoSpot 50 is intended exclusively for installation in an outside wall, where the side air passage openings must be located on the inner side, vertically and with the thumb wheel for shutter adjustment on the right side.
Installing the ventilation unit DANGER Fatal voltages Disconnect all poles of the mains cable intended for connection to the ventilation unit from the power supply before carrying out installation and maintenance work. Proceed as follows for the installation of the unit: NOTE Optional accessories, such as sensor modules and wireless or wired operating modules, must be fitted into the unit before installation.

Parameterisation of boost ventilation and absent operating modes As described in “3.1.6 Description of the operating functions and signals”, the boost ventilation and absent operation modes can be adjusted according to user-specific needs. NOTE Parameterisation must be carried out in the accessible status of the control board. Configuration of the boost ventilation mode The temporarily active fan speed 4 operates as the boost ventilation function.
2. Using the raised contours for the airflow, put the bottom cover of the outside wall panel onto the EPP housing, and fasten it on the four fixing points on the wall mounting pipe. NOTE Then screwing the bottom cover to the wall, the bottom cover of the outside wall panel must not bend! If necessary, undo the screws again so that the bottom cover of the outside wall panel is still fitted tightly to the façade, but this does not cause any deformation.
