7.2.5
Quick charge function
This function attempts to load the upper part of the storage tank more
quickly by means of a higher loading temperature in order to prevent
conventional boiler back-up heating as early as possible.
When the temperature in the upper part of the storage tank falls below
the "on" value, the loading strategy of storage tank 1 switches from
differential loading to target temperature loading. The controller's RPM
control is then used with the objective of loading the storage tank at a
higher temperature level.

tank, and switch-on/switch-off temperatures

SET: press button to confirm.
The settings are saved.
NOTE
When the "on" value is adjusted, the "off" value is altered accordingly in
order to maintain reliable quick charge functionality.
7.2.6
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 approximately calcu-
lated 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.

proportion
