8 Fault
8.1 Fault analysis
When the appliance's control system detects a fault, this is indicated on the display by a spanner symbol, possibly
also with a fault number.
The appliance makes a distinction between a fault at which the appliance keeps running (limitedly) and a serious
(locking) fault for which both fans are switched off.
8.2 Display Codes
Non-locking fault
When the appliance detects a non-locking fault, it will keep running (limitedly). The (permanently lighted) display
shows the fault symbol. Press the fault symbol for an explanation/ solution to the fault.
The screen can be left by pressing the "Home" button.
If a fault cannot be solved, please contact the installer.
1. Requested supply flow rate is not reached
Locking fault
When the appliance detects a locking fault, it will no longer work. With a locking fault the settings and
information menu are also switched off.
The (permanently lighted) display shows the fault symbol (spanner) together with a fault code. The red LED on
the multiple switch (if applicable) will be blinking. 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 returns to the display of
the operating situation. Contact the installer to remedy this fault.
1. Supply fan defective
A locking fault cannot be remedied by taking the voltage from the appliance; first the fault has to be solved.
