Outdoor air compensation menu (NTC 2 Temp)
The outdoor air compensation function (NTC 2 installed)
can be used to control the fan speed as a function of the
outdoor temperature. When the outdoor temperature
drops below the temperature set for starting the
outdoor air compensation function, the fan starts
to decrease the fan speed linearly by the specified
percentage, until the end temperature for outdoor air
compensation is reached. The fan speed is restricted
by a specified percentage when the outdoor air
compensation end temperature is reached.

compensation menu.
