These parametrizing options are only available when the amount of energy is still <= 10 kWh.
Make sure that these
characteristics are set as needed before starting up the system.
Setup by pushing the button: In order to start the editing mode for parametrizing you must select the respective item in the
parametrizing loop and then push the button once again for 2-3 seconds. As an aid, after 2 seconds the „editing pen“ will be
displayed bottom left in the LCD (see below picture). As soon as it appears you have to let go of the button. Then the current
display will start blinking.
By pressing the push-button briefly you can switch to the next option. By pressing the push-button longer the currently
displayed option will be set. If no option is chosen there will be no change and as soon as the LCD goes out the edit mode will
end automatically.
b) The following characteristic of those calculator types designed to be used with glycol can be set on location
at any time
using the „Device Monitor“ software:
-
type and concentration of glycol in the medium
(propylene glycol; ethylene glycol; 20 %; 30 %; 40 %; 50%).
