Operating Manual geoTHERM exclusive VWS 0020071929_0018

Display shown Description

Energy input display

Shows the energy extracted from the environment for each of the 12

months of the current year (black bar). White-filled bars represent the

future months of the year; the height of the bar corresponds to the

yield for the month in the previous year (comparison possible). On

commissioning, the height of the bars is zero for all months, as no in-

formation is available yet.

The scaling (in the example, 4000 kWh) adapts automatically to the

month's highest value.

Top right the total of the environmental yield since commissioning is

displayed (in the example: 13628 kWh).
