Systems

Arrangement 1: Standard solar system
The controller calculates the temperature difference between collector sensor S1
and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference (DT O), the solar pump will be activated by relay
1, and the store will be loaded until the switch-off temperature difference (DT F) or
the maximum store temperature (S MX) is reached.
Sensors S3 and S4 can optionally be connected. S3 can optionally be used as the
reference sensor for the store emergency shutdown option (OSEM)

If the heat qunatity measurement option (OHQM) is activated, S1, S4 or VFD can be
used for measuring the temperature (see table on p. 63).
If the drainback option (ODB) is activated, relay 2 can be used for activating a
booster pump. For this purpose, the booster function (OBST) has to be activated.
