<strong>Diag</strong>nostic <strong>unit</strong><br />
order no. 22 1545 89 00 00<br />
The diagnostic <strong>unit</strong> is solely used to read out, display and delete faults<br />
stored in the heater's electronic control box.<br />
The electronic control box can store up to 5 faults (exception: auxiliary<br />
heater D 3 W Z).<br />
The current fault is displayed as "aF" and a 2-digit number and is<br />
always written in memory location F1.<br />
The stored faults "F1" to "F5" can be queried.<br />
usability of the <strong>Diag</strong>nostic <strong>unit</strong><br />
The diagnostic <strong>unit</strong> can be used together with the corresponding<br />
adapter cable for the following heaters:<br />

Please note!<br />
always follow the given order of steps.<br />
The test duration is limited to max. 1<strong>20</strong> minutes.<br />
The bl/ws diagnostic cable must be connected in order to perform<br />
the diagnosis. To this end, note and follow the circuit diagram in the<br />
technical description of the heater.<br />
Ensure adequate battery voltage (min. 10.5 V / min. 21 V).<br />
not only the defective component, but also a defective current path<br />
results in a fault being displayed.<br />
The fault code, fault description, cause / remedial action are<br />
described in the heater's troubleshooting.
PerforM the <strong>Diag</strong>nosis<br />
automatic detection<br />
Five seconds after the diagnostic <strong>unit</strong> has been connected to the heater<br />
using the adapter cable, the automatic detection starts to determine the<br />
type of heater to which the diagnostic <strong>unit</strong> is connected.<br />
Please note!<br />
if the automatic detection was successful, if necessary, the heater is<br />
briefly started and then switches off again.<br />
Display until the automatic detection is completed.<br />
Display<br />
if a water heater has been detected<br />
if air heaters 1l, 3l, 5l or airtronic, airtronic<br />
m, airtronic l air heaters (control box<br />
cable loom fixed, moulded) were detected.<br />
Display,<br />
if the airtronic, airtronic m, airtronic l air<br />
heaters (control box cable loom wound with<br />
cable tape) were detected.<br />
Confirm flashing symbol with<br />
possible displays:<br />
if no errors/faults exist<br />
further action –> display fault memory,<br />
