AST 14 C 257/00
Flow probe o return probe > 120 C°
(a)
Shutdow n due to max. flow derivative threshold exceeded
(r)
Shutdow n due to max. return derivative threshold exceeded
(r)
Pow er reduction due to high flue gas temperature*
(f)
Maximum number of remote reset attempts reached
* Errors E81, 82, 83, 84 and 88 are not displayed in real time. They are recorded on the shutdow n
counter under super-technical parameters (P01 to P05).
Im portant. They can be view ed on the display by setting super-technical parameter P90 to 1.
(f) = flow (r) = return
Malfunctions - errors resettable by the technical service only
Particularly serious shutdowns (see table below) required the intervention of the technical
service.
Press the reset and b oiler mode buttons simultaneously. The spanner icon will appear, to
tell you that you can reset the boiler by pressing the reset button.
Flue gas temperature low er than the return T
Maximum flue gas
threshold exceeded
Alarm due to maximum flue gas derivative threshold
exceeded
