8.1 Trouble shooting
When the appliance control system detects a fault, it is indi-
cated on the display with a spanner symbol, possibly together
with a fault code.
The appliance makes a distinction between a fault at which the
appliance keeps running (limitedly) and a serious (locking) fault
at which both fans are switched off.
In case of locking fault, the settings and readings menu is swit-
ched off as well and only the service menu is available.
The appliance remains in this fault mode until the problem in
question has been solved. Then the appliance will reset itself
(auto reset) and the display will once more show the operatio-
nal mode.
Fault E999
If, when the appliance is powered up directly to message E999
appears on the display, the mounted control board is not sui-
table for this appliance or the dip switches on the control board
are set incorrectly .
For the location of the dip switches see § 10.2; position M
In that case, check whether the dip switches on the control
board are set as shown in the drawing of the dip switches set-
tings; if they are, and the message E999 still appears, then
replace the control board by a board of the correct type.
8.2 Display codes
Non-locking fault
When the appliance detects a non-locking fault, it will still keep
running (limitedly). The display does show the fault symbol
(spanner).
Locking fault
When the appliance detects a locking fault, it will no longer
work. The (permanently lighted) display shows the fault symbol
(spanner) together with fault code. The red LED on the multiple
switch (if applicable) will be blinking. Contact the installer to
remedy this fault. A locking fault cannot be remedied by taking
the voltage from the appliance; first the fault must be solved.
The fans are controlled on the basis of the value of the pres-
sure sensors mounted on the control board. For each fan 2
pressure hoses run to the control board. If these hoses are
not connected as prescribed, or if they are leaking or blocked,
a wrong pressure will be measured so the fans can no longer
be controlled correctly. In case of doubt on the correct perfor-
mance of the appliance, check the pressure hose connections.
