6. Examples
6.1 Solar system with 1 collector and 1 store with
heating reverse raising
The controller measures the temperature difference between
collector sensor S1 and store sensor S2. As soon as this
difference is higher or identical to the adjusted value for
switch-on temperature difference (DO/1), the pump (R1) is
activated and the store is loaded until the switch-off
temperature difference (DF/1) or the maximum store
temperature (SX/1) is reached. Independently from the so-
lar circuit a
∆
T-reverse raising is simultaneously effected. If
the switch-on temperature difference (DO/2) of the sensors
S3 and S4 is exceeded a 3-way valve is activated for heating
circuit support by relay output R2.
