Hello,

During commissioning of an ALS F SE 296.3 McQuay chiller I notice that the opening of the EXV has an important variation in a short time. The superheat also have a major variation. Also I notice that this variation is linked with fan step changes.
Commissioning was performed at 5 degree outdoor temperature, and I suppose that is the reason for this behavior.

Colud be other reasons for this phenomena?

Thanks in advance for your opinions.
Nicola
