9.2.25 Diagnostics cascade/heat generation/consumers
Diagnostics cascade/heat generation/consumers (8100-9058)
Displays of different setpoint and actual values, relay switching statuses
and counter statuses for diagnostics purposes.
Gas energy
There are 6 energy meters available, comprising the estimated gas energy
used with the aid of the fan speed and a linear approximation of the actual
burner output. The energy meters must be switched on and off using
prog.no. 2550. The results can be corrected under prog.no. 2551.
2 overall meters can be reset on the engineer level:
Prog.no. 8378: Total gas energy heating
Prog.no. 8379: Total gas energy DHW
The end consumer can reset 2 meters:
Prog.no. 8381: Gas energy heating
Prog.no. 8382: Gas energy DHW
Important
Prog.no. 8380 and 8383 are the result of adding the previous
parameters.
9.2.26 Burner control
Prepurge time (9500)
Pre-venting time.
Caution
This parameter must only be changed by a heating specialist!
Required output prepurging (9504)
Nominal output fan speed during preventing.
Required output ignition (9512)
Nominal output fan speed during ignition.
Required output LF (9524)
Nominal output fan speed under boiler in part load.
Important
If you change this value, please note that prog.no. 2452
(Controller delay fan output) is always higher.
Required output HF (9529)
Nominal output fan speed under boiler in HF
Postpurge time (9540)
After-venting time.
Caution
This parameter must only be changed by a heating specialist!
Fan output/speed slope (9626) and Fan output/speed Y-
section (9627)
The speed of the fan can be adjusted with this. This is important for
complex installations or change to LPG.
Prog 9626 corresponds to the slope of the fan curve
Prog 9627 corresponds to the displacement of the fan curve in Y-
direction
