Figura 11: Evosta3 Display
The Evosta3 circulator has a display that is able to show the following values.
Height of the selected curve (1-2-3)
Instantaneous power absorption in Watt
Instantaneous head in m
Instantaneous flow rate in m3/h
The values are shown in sequence for 3". Once the viewing cycle is ended, the display switches off and only the operating mode LED remains lit.
If the selection key is pressed within 10", the display performs 6 viewing cycles, then goes into stand-by.
If the key is pressed again within 10", the display performs 11 more viewing cycles to allow a greater reading time.
