Heat quantity function
The controller has a function for measuring the quantity of heat.
This allows, for instance, to record the quantity of heat fed into the
storage tank from the solar energy system. To do this, the tempera-
ture of the supply and return, and the flow rate of the solar energy
system must be recorded. The flow rate can be read in via a pulse
generator, recorded via a special Direct Sensor, or approximately cal-
culated by means of the pump speed. Since the heat quantity depends
on the proportion of glycol in the fluid, this also is accounted for in the
calculations. From these values, the controller determines the quantity
of heat and shows this in the display.
NOTE
When using the Direct Sensor, observe the manufacturer's technical data.
