Level 5
The controller compares the temperatures at the collector
sensors S1 and S5 to the store temperature at sensor S2. If
one of the measured temperature differences is higher than
the adjusted switch-on temperature differences, the corre-
sponding pump (R1, R2) or both pumps will be activated and the store will be loaded.
With another temperature differential function (S3-heat
source/S4-heat sink) heating circuit return preheating (he-
ating circuit backup) is possible with another valve (R3).
