How many?

The Auto mode on the Aero 100 and the Pro 150 controls the settings of the equipment so easily that the type of machine you require, and the number, is simply a factor of how many rooms you have and their respective size.

In square metres, one room under 100m2 should be easily serviced by an Aero 100. 

For a single room sized between 100-150m2, one Pro 150 should do the job. If you have a space that exceeds 150m2 you will need a combination of units to suit. You can use 100s and 150s alongside each other with ease. Each unit has its own sensor and control so interchangeability is simple.
