Tab. 1: Terminal pin assignments
1)
Terminal pin assignments for 0–10 V-controlled high-efficiency pumps: The power supply must
be connected to output R1 (N, PE); the control cable for the pump electronics must be con-
nected to 0–10
R1 and
2)
Terminal pin assignments for 0–10 V-controlled high-efficiency pumps: The power supply must
be connected to output R2 (N, PE); the control cable for the pump electronics must be con-
nected to 0–10
R2 and .
3)
Installation regulation: When no power is supplied to the switching valve, then no flow occurs
through the storage tank.
4)
Installation regulation: When no power is supplied to the switching valve, then the lower part
of the storage tank (T2) is loaded.
5)
Installation regulation: When no power is supplied to the switching valve, then the first priority
storage tank (T2) is loaded.
6)
Installation regulation: When no power is supplied to the switching valve, then the storage
tank (T2) is loaded.
