3.26 Burner hours run stage 2 (tBR2)

Auxiliary value for ascertaining the average load on the boiler.
Display
0...65535
The actual number of hours run of burner stage 2 will automatically be displayed on this
line.

3.26.1 Counting the hours run

The hours run of burner stage 2 are counted with the signal received from output K5.
But this is the case only when voltage is present at E1.
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.

3.27 Number of burner starts stage 1

Auxiliary value for ascertaining the average burner hours run.
Display
0...65535
The number of starts of burner stage 1 will automatically be displayed on this line.
The number of starts of burner stage 1 are counted using the signal received from
output E1 (e.g. the fuel valve). The input signal voltage must be 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.
