Data
Description
0000
In case of pulse signal (JP001 on AHU main PCB A1 closed)
for each pulse signal change from current operation ON to OFF
respectively from current OFF to ON state
In case of static signal (JP001 on AHU main PCB A1 open) NC =
operation ON, NO = operation OFF
0001
"OFF reminder function"
With JP001 on AHU main PCB A1 closed: NC = RC operation
possible, NO = operation OFF and RC usage prohibited
JP001 on AHU main PCB A1 open: NC = no change, NO = unit
operates at upper temperature limit setting in cooling and at lower
temperature limit setting in heating (does not work in Fan mode
or Auto mode)
0002
"Fire alarm function"
JP001 status invalid. NC = operation stop and RC prohibited, NO
= RC usage possible
0000

No RAP valve control
0001
With RAP valve control
-001 ... 0026
For the first 6 minutes after heating operation start, the fan
remains OFF until max. E1, E2 or BL temperature exceeds the
set value + 10 K. If 3B = 0001, the temperature limit value is
shifted down by 17 K.
