Control Panel Communication
The control panel provides operator interface with the climate control system.
Control panel operation is described in detail in the D section.

System Self-test
Control Panel Interrogation Procedure
The control panel has a self-diagnosis feature, and is capable of displaying and clearing stored fault codes.
Climate control is an integrated system, therefore it is recommended that the PDU is used for fault diagnosis. The fault
codes displayed with the control panel self -diagnosis feature are not as comprehensive as those of the PDU. The PDU will
display the relevant fault code, fault co de description and information of the system peripherals at the time the fault
occurred.
Fault Code Extraction and Deletion Procedure
Error information is stored in the A/CCM up to a maximum of 5 faults. Should a sensor fault occur there will be an audible
beep and the message Er will be displayed on the control panel display for 5 seco nds after ignition on. Please note that this
will happen only once in any ignition switch cycle. The error source may be accessed by the following procedure
This procedure must be completed through one complete cycle, 1 through 6
• NOTE: * Actuator codes do NOT equate to system fault codes.
• NOTE: Only codes 11, 15 and 21 (see Fault Code List ing) will cause audible beep and 'Er' display.
• NOTE: If '0' is displayed, there are no stored faul t codes, wait 30 seconds to allow system self-test.
The control panel display will flash repeatedly indicating a list of two digit numbers (see table for code analysis). Should a code be displayed accompanied by an audible beep, the fault is current and therefore still present within
the system. A code displayed without an accompanying 'bee p' indicates a fault had previously occurred but is not
present within the system.
• NOTE: It is advisable to check all areas indicated with cleared fault codes. Such faults may re-occur if intermittent
problems are present in the system.
To delete stored and cleared fault codes press 'R' and 'FAC E' buttons simultaneously. After investigating and correcting all stored faults, press the 'Push Off' button to restore normal operation with
default panel settings, ie AUTO at 24°C.
