2.3.2 Sliding window demands
Note
This function will be av
ailable at a later time via a 󹪝rmware update.
The sliding window demand value is the arithmetic mean of all measured values that occur
within a
con󹪝gurable averaging time. "Sliding" means that the interval for the demand
calculation is continuously shifted as a function of time.
