4.3.6 Type = Flow
The process is based on the hydraulic alignment related to the flow. For this purpose, a
flow sensor is installed in each circulation line with a hydraulic alignment valve and con-
nected to the controller, see
Installing a flow sensor .
The process is started daily at a specific start-up time .
The starting time must be selected so that the process takes place at a time when no
hot water is withdrawn, i.e. typically at night. The valves sequentially adjust to the set
flow , for a maximum of 4 hours, and then maintain the set opening angle until the next
regulation phase.
The first period after activation of the hydraulic alignment of type flow is used to determ-
ine the basic data. The first hydraulic alignment is only executed in the 2nd regulation
phase (2nd night). With each additional regulation phase, the opening angle of the
valves is further optimized. Depending on the complexity of the drinking water install-
ation, 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. For this purpose, enter the pipe volume (volume of
the entire circulation line), see
Pipe volume (-> settings -> valves) .
