Level 5
The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S4. 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). Store 1
is loaded with priority. Heat exchange from store 1 to store
2 (R2) is possible with another temperature differential
function (S3-heat source/S4-heat sink).
