Χp
max
= max. permissible differential pressure across the valve’s control path, valid for the entire
actuating range of the motorised valve
Χp
S
= max. permissible differential pressure (close off pressure) at which the motorised valve will
close securely against the pressure (used as throughport valve)
S
NA
= nominal apparent power for selecting the transformer
P
med
= typical power consumption
I
N
= required slow fuse
k
VS
= nominal flow rate of cold water (5 to 30 °C) through the fully opened valve (H
100
) at a
differential pressure of 100 kPa (1 bar)
L = max. cable length; with 4-wire connections, the max. permissible length of the separate
