8.2.2 Calling up the Hour Counter
NOTICE
The sum of the curve set 1 running hours and curve set 2 running hours does not necessarily
give the running hours value, which is displayed in total. The total counter relates to the VMS
running hours. It runs as soon as the unit is connected to a power supply (this also provides
the basis for the fault history).
The single running time meters relate to the burner running hours. These run as soon as the
burner is in operation with the respective curve set (flame signal to the VMS).
Turn selector switch (1) to SETPOINT
the display shows a moving text with the following
content:
– total running hours
– running hours on curve set 1
– starts on curve set 1
– running hours on curve set 2
– starts on curve set 2
If you use the 4 curve set or 8 curve set option the dis-
play shows the running hours and starts on the addi-
tional curve sets.
