The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S3. If the measured tem-
perature 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 adju-
sted maximum temperature via the valve (R3). The priority
logic effects prior loading of the upper zone of the store.
