In the diagnosis codes 80 to 83 5 digit figure values are stored. When selecting e.g. d.80 only the first two digits of the figure value are displayed
(e.g.10). By pressing the „i“ key, the display switches over to the last three figures (e.g. 947). The operating hours counter of the heating in this case
would be 10947 h. Pressing the „i“ again causes the display to switch back to the diagnosis point that was called up.
