Level 5
The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S3. If the measured
temperature differences are higher than the adjusted switch-
on temperature differences, the pump (R1) will be activated
and the corresponding store zone will be loaded up to the
adjusted maximum temperature via the valve (R3). The priority logic effects prior loading of the upper zone
of the store.
Heat exchange control to an existent store via an additional
pump (R2) can be carried out with another temperature
differential function (S3 heat source/S4 heat sink).
