P450 In Home Energy Monitor - DRAFT User Manual
The communication error screen can be seen in the following example.
Figure 108 Communication Error Notification Screen
On selection of the Connect button the P450 IHEM will then go into a search process to re-establish
communication with the Electricity Meter. During this time the P450 IHEM will show a searching
screen with a supporting message that it may take up to 3 minutes to complete the connection
process.
An example of the attempting to establish communication screen can be seen in the following image.
Figure 109 Searching Meter Screen
Once communication has been re-established the P450 IHEM will return to the Home Screen. If
communication cannot be established then the P450 IHEM will return to the Communication Error
screen where the user will be advised to try another location, and to select the connect button.
This process can be repeated up to five times, after the fifth attempt the P450 IHEM will display a
message stating that no response has been received from the meter, and that the customer should
contact the utility.
The screen also contains a connect button to attempt further retries, and an Admin button which on
selection would direct the user to the unbind screen. This should only be accessed by service
engineers or customer service persons to perform an unpairing of the meter and P450 IHEM as part
of further detailed process management.
