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 tank zone will be loaded up to the 
adjusted maximum temperature at most via the valve (R3). 
The priority logic effects prior loading of the upper zone 

of the tank.
With another temperature differential function (S3-heat 
source/S4-heat sink) heating circuit return preheating (he-
ating circuit backup) is possible via another valve (R2). Do-
mestic hot water backup heating (R4) can be carried out 
with a thermostat function (S3).
