The routine for joining is very simple: If the P450 IHEM determines it is in an un-joined state when it powers on it will scan to find ZigBee Smart Energy networks available for joining. When an internal list of available networks opens for joining has been compiled; the P450 IHEM will attempt to join each in turn. Only the network that has been instructed to allow that specific P450 IHEM to join will permit joining; successful joining therefore requires registration of the P450 IHEM device with the Utility. Registration of the P450 IHEM device with the utility could be an end user driven process as described immediately below or may alternatively be part of an integrated commissioning process applicable to a wider smart meter installation as described further below. 3.1.1 Consumer controlled joining If an end user is expected to register the P450 IHEM with the utility themselves the steps below need to be described or elaborated in any end user literature provided to them: 1. To register the P450 IHEM with your utility contact your energy supplier at the contact point they have provided (web portal or telephone line) with the Installation Code and MAC address to hand. You will find the Installation Code and MAC address on the product packaging and on the label in the battery compartment of the P450 IHEM. You may need to remove the battery compartment cover if you have already fitted it as the label is in that recess. 2. After communicating your product Installation Code and MAC address to your energy supplier; return to the P450 IHEM and connect to the mains. This will initiate a join to the Smart Energy network. Your energy supplier will do the rest and your P450 IHEM will join the Smart Energy network shortly. When it has joined the network the P450 IHEM will display the home screen.

The centre framed display element is reinforced by a qualitative indicator (analogue gauge) of the same basic information. 6.6.1 Accumulation The analogue gauge below is used to reinforce the display of any accumulating quantity and display of consumption status relative to budget. The gauge may be represented like this: Figure 15 Analogue Gauge Example The gauge ‘fills up’ left to right revealing coloured segments as it does so. The segments are an analogue indication of accumulating and accumulated quantity relative to the target (budget) set for that day.
Page 28 of 90 Issue: 0.4 Using your P450 IHEM © Landis+Gyr Commercial in Confidence. © Landis+Gyr P450 In Home Energy Monitor - DRAFT User Manual Operation of the analogue gauge is defined as:  Green segments indicate accumulation is less than target so far; or quantity accumulated so far is acceptable  Amber segments indicate target value is being approached; or quantity accumulated so far requires attention (control)  Revealed red segments are used to indicate the target has been exceeded; or quantity accumulated is high. The gauge retains the same appearance regardless of whether the framed display item beneath it is the % consumed of today’s target or an accumulating monetary values or kWh values. 6.6.2 Instantaneous This specific analogue gauge accompanies and reinforces the framed display of any instantaneous (rate of usage) value. This framed display element may be: $/hour / now and Watts or kW/ now. The gauge may be represented like this: Figure 16 Analogue Gauge The gauge segments may move left and right into the green, amber and red areas. When an electricity quantity is on display the status of this gauge will be directly related to the traffic light light-bar above it. Example:  The gauge will be in the green area when the light-bar feature is illuminated green,  The gauge will show amber segments when the light-bar is illuminated amber  The gauge will show red segments when the light-bar is illuminated red.

Figure 72 Invalid Code Entry Screen 11.7 Code entry lockout mechanism The P450 IHEM supports a code entry mechanism which will stop misuse of the code entry screen for payment and emergency code support. The following section details the operation of the lock-out mechanism.
Page 60 of 90 Issue: 0.4 Prepayment Function © Landis+Gyr Commercial in Confidence. © Landis+Gyr P450 In Home Energy Monitor - DRAFT User Manual 11.7.1 10-minute lock out The P450 IHEM will allow the user 3 attempts to enter a code during a 5-minute time frame before the first lock out mechanism is applied. Once the 3 failed attempts have been performed the P450 IHEM will disable access to the code entry screen for 10 minutes. The lock out will be displayed on the P450 IHEM in a visual message stating: ‘Code entry is disabled Try again in 10 minutes’. This can be seen in the following example. Figure 73 Code Entry Disabled for 1 Minute Once a lock out message has been displayed the user can still operate all other functionality of the P450 IHEM except the code entry screen. If the user attempts to re-access the code entry screen the previously displayed message will be shown to the user once again. The message will not be updated or cleared from the screen until the defined lock out period has finished. 11.7.2 1 hour lock out If the user again attempts to enter a code after the end of the first lock out period, then the P450 IHEM will allow 3 further attempts during a 1 hour time frame to enter the correct code before the second lock out mechanism is applied. Once the 3 further failed attempts have been performed the P450 IHEM will disable access to the code entry screen for 1 hour.
Prepayment Function Issue: 0.4 Page 61 of 90 P450 In Home Energy Monitor - DRAFT User Manual Commercial in Confidence. © Landis+Gyr © Landis+Gyr The lock out will be displayed to the meter in a visual message stating: ‘Code entry is disabled Try again in X minutes’ (duration remaining on attempt to enter code). This can be seen in the following example. Figure 74 Code Entry Disabled for 1 Hour 11.7.3 24-hour lock out If the user again attempts to enter a code after the end of the second lock out period, the P450 IHEM will enter a period where 3 final attempts to enter the correct code will be allowed during a 24-hour time frame before the final lock out mechanism is applied. Once the 3 further failed attempts have been performed the P450 IHEM will disable access to the code entry screen for 24 hours. The lock out will be displayed to the meter in a visual message stating: ‘Code entry is disabled Try again in X hours X minutes’ (duration remaining on attempt to enter code). This can be seen in the following example. At the end of the 24-hour period the lock out mechanism is reset and will again operate as defined in examples 1, 2 and 3 again. Figure 75 Code Entry Disabled for 24Hours NB: To mitigate any potential over use of the lock out mechanism the P450 IHEM will automatically lock out the user for 24 hours after 10 failed attempts in any one day are registered in the P450 IHEM. 11.8 Emergency credit The Emergency Credit function is selected from the prepay menu screen.
