4.3.5 Type = Temperature static
The process is started daily at a specific start-up time . The starting time must be
selected so that the process of static hydraulic alignment takes place at a time when no
water is withdrawn, i.e. typically at night.
Process sequence
At the start of the process, the opening angle (leakage rate) of each single valve
is set. During this, the valves sequentially adjust to the flexible average tem-
perature of the past 24 hours and the set
nominal temperature . The valves
maintain this set opening angle for 24 hours until the next regulation phase.
The first period after activation of the hydraulic alignment of type temperature,
static is used to determine the basic data (determination of average values for 3
hours and 24 hours). The first hydraulic alignment is only executed in the 2nd
regulation phase (2nd night). With each additional regulation phase, the open-
ing angle of the valves is further optimized. Depending on the complexity of the
drinking water installation, optimal hydraulic alignment may require several
nights.
Providing the specific water content of the pipe on which the alignment valve is
installed can expedite the process (optional). For this purpose, enter the pipe
volume (volume of the entire circulation line), see
Pipe volume (> valve > set-
tings) . The pipe volume is a proportional factor that affects the adjustment steps
and thus helps the system to adjust faster.
If the average temperature of the past 3 hours falls below the temperature
lower limit , a new ideal valve position is immediately calculated and the open-
ing degree (leakage rate) is adjusted. This safety correction is carried out no
more than 1 time per valve and regulation phase.
