Technical information

28. Laptop Connection
The EC25 has a special serial connection
that can only be used by the installer for
diagnosis with a PC.
The special cable and software required are
available to the installer as an option. Never
use a standard cable; this will result in
damage to the PC!
The software possibilities are:
28.1 Display current status
This screen gives the installer the possibility
to display an overview of the complete
status of the control system. This screen
gives the following information:
current temperatures as measured by the
control system
current and requested fan speed
status of the control system
measured ionization level
parameters that can be modified by the
installer
The status screen has a number of
pushbuttons with which several parameters
can be changed, such as the minimum and
maximum fan speeds.
28.2 History screen
The control system keeps a record of the
following data:
date of manufacture
number hours that the control system has
been active
number of successful ignition attempts
number of failed ignition attempts
number of flame faults
number of hours of burning for central
heating use
last 16 blockages
last 15 interlocks
These data will be saved in the memory of
the control system and will be maintained,
even when the power supply is switched off.
28.3 Graphic screen
This part of the programme gives the
installer the possibility to see a graphic
presentation of all measured temperatures
and other variables (such as fan speed). If
desired the measured values can be saved
on a diskette.
The saved information can later be
displayed or printed.
