Arrangement 7: Solar system with east-/west collectors and 1 store
The controller calculates the temperature difference between collector sensors
S1 and S3 and store sensor S2. If the differences are larger than or identical to the
adjusted switch-on temperature difference (DT O), one or both pumps will be acti-
vated by relay 1 and / or relay 2, and the store will be loaded until the switch-off tem-
perature difference (DT F) or the maximum store temperature (S MX) is reached.

Sensor S4 can optionally be used as the reference sensor for the store emergency
shutdown option (OSEM). If the heat quantity measurement option (OHQM) is acti-
vated, S4 or VFD can be used for measuring the temperature (see table on p. 63).
