10.3.7 Upper storage tank display
Shows the temperature in the upper region of the storage tank. For this,
an appropriate sensor must be connected to the tank. The measured
temperatures are not used for control purposes.

Calculates the acquired heat volume based on the following information:
• Supply temperature
• Return temperature
• Flow rate volume determined via calculations based on the pump
speed or by pulse water meter measurements (terminal
5
).
Note
Calculation based on the pump speed cannot be performed when
No System (System
0.1
) has been selected.
• Glycol proportion and accounting for the temperature-dependent
thermophysical properties of the heat transfer fluid.
Additional possibility: Display of the amount of CO
2
saved by using the
system. The amount of CO
2
is calculated from the acquired heat volume.
To do this, the controller requires the conversion factor
