The controller compares the temperatures at the temper-
ature sensors S1 and S6 to the temperature at sensor S2. If
one of the temperature differences measured is higher than
the adjusted switch-on temperature difference, the pump
(R1 or R2) will be activated; the solar circuit will be heated.
The controller will aim to hold the adjusted temperature
difference. The pump speed is controlled such that the ad-
justable temperature difference is reached.

(Scheme number 004 / 014)
If the temperature difference between S3 and S2 exceeds
the adjusted switch-on temperature difference for the sec-
ondary pump (external heat exchanger), the pump (R3) will
be switched on. Store loading is controlled by means of an
additional heat exchange function. The valve (R4) is normal-
ly open to load the central store zone.
If the temperature difference between S5 and S7 exceeds
the switch-on temperature difference, the upper store
zone will be loaded up to the adjusted set temperature.
