6.0 ERROR MESSAGES
While your system is operating, the Networker monitors and
controls every aspect of the system's performance. On-board
diagnostics help determine the source of a fault. If a fault is
detected the system may turn off completely, or in some cases
attempt to automatically restart.
When a fault persists, the Networker may display, for example,
“Heater Fault” and the (spanner ) symbol. The message will
vary depending on the nature of the fault and the type of heating or
cooling system (see Diagram 19).
Note: If an invalid PIN is entered, the message "Invalid PIN entered
- try again" will scroll across the screen. The user has three
attempts at entering a valid PIN. On the third failed attempt the
message "Invalid PIN entered!" will be displayed. At this point the
Networker will abort the PIN entry screen, and return to its original
screen . You will then need to repeat the process.
