2
Parallel
(storage tank charging and swimming pool heating at the same time)
Both the swimming pool and the storage tank make use of solar energy at the
same time as long as the solar collectors are able to deliver sufficient amounts.
First, the pump of the priority storage tank will be put into operation. If the amount
of energy available from the solar collector is sufficient, the pump of the nonpriority
storage tank will also be put into operation. If solar energy is still available, the
pump for swimming pool heating will also be activated.
The pumps will be deactivated in the reverse order.
The priority is to be selected on operating line 333.
If, in addition to the swimming pool, there is only one storage tank, the swimming
pool will be heated with priority 2.
If there are 2 storage tanks that cannot be charged at the same time, swimming
pool heating is started parallel to priority storage tank charging. When the priority
storage tank has reached its setpoint, the valve changes over to charge the non-
priority storage tank. Swimming pool heating will be maintained as long as the so-
lar collector is able to deliver sufficient amounts of heat.
The hydraulic circuit used must not prevent the selected operating mode (alternative /
parallel)!
4.85 Measured value correction
swimming pool sensor B13
•
More accurate display of the swimming pool temperature
•
More accurate generation of the temperature differential
•
Compensation of long sensor lines
Calibration of the swimming pool sensor and compensation of the line lengths ensure
that the display of the effective temperature will be more accurate.

The sensor characteristic is displaced parallel by the selected value.
When entering a negative value, the temperature measured will be lowered by that
value, when entering a positive value, it will be raised by that value. The readjusted
temperature will be displayed on operating line 318.
