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.

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.
Warning!
When working on the appliance, always first take the voltage from the appliance by
pulling the power plug.
