The actual number of hours run of burner stage 2 will automatically be displayed on this
line.
1.23.1

Counting the hours run

The hours run of burner stage 2 are counted with the signal received from output K5.
Counting takes place independent of whether manual reset safety limit thermostats or
thermal reset limit thermostats switch off the safety loop. It should therefore be ensured
that such thermostats do not affect burner operation. If this is not observed, too many
hours will be counted.
Each time 2 full operating hours are registered, the new value will be written to non-
volatile memory. Only full hours are displayed, and no minutes.
This means that if the display is checked again after a short period of time, it may still
show the previous reading, if the second burner stage has not yet completed another 2
operating hours.

Number of burner starts stage 1

Auxiliary value for ascertaining the average burner running time.
Display
0...65535
The number of starts of burner stage 1 will automatically be displayed on this line.
The hours run of burner stage 1 are counted based on the signal received from output
K4. The voltage of the output signal is AC 230 V. Display of the number of burner starts
is updated each time the burner is started up.
The number of burner starts is written to non-volatile memory at 2-hour intervals or
whenever there is a power failure.
