Valve logic
Flow direction when the
valve is normally open
The controller compares the temperatures at the collector sensors S1 and S3 to
the tank temperatures at the sensors S2, S4 and S5. If one of the measured tem-
perature differences is higher than the adjusted switch-on temperature differences,
the corresponding pump (R1, R2) will be activated and the corresponding tank will
be loaded up to the adjusted maximum temperature via the valves R3, R4. In this
system, one of the tanks can be loaded with priority.
