24.4. Boost Functionality
The meter has the functionality that allows the Customer to turn on the ALCS / HCALCS for a period of time. This will only
be possible if the meter has been configured so that a particular ALCS / HCALCS will operate in accordance with the
Boost Switch. This configuration can be done and changed at any time from the DCC. All ALCS / HCALCS configured to
operate in accordance with the Boost Button will operate simultaneously i.e. there will be no local option to individually
select which ALCS / HCALCS will operate.
The Boost Function is initiated by pressing the Push Buttons when the meter is displaying an appropriate display (or from a
Type 1 Device).
The Boost Function will allow the ALCS / HCALCS to be switched on for either 15, 30, 45 or 60 minutes after which time
the ALCS / HCALCS will revert to normal operation (using the ALCS Switching Calendar). If the auxiliary is closed by the
boost functionality the top right hand 5 characters of the display will show ‘boost’.
Once Boost is selected the following options are available:
• Cancel the Boost
• Extend the Boost by 15, 30, 45 mins, providing the total boost time of 60mins is not exceeded
If a Power Outage occurs during a Boost Period then the meter will stop the Boost Period in line with the current amount of
boost select e.g., if the meter had a Boost Period configured from 7:30 to 8:00 (30min Boost) and there was a Power Cut
from 7:40 to 7:50 then the Boost Period still finishes at 8:00.
While Boost functionality is active there will be 2 displays added to the General Display Menu:
• Activate Boost:
Choose one of the available periods: 15, 30, 45 or 60.
Use "NEXT" button to navigate between options.
Use Long press on "SELECT" button to active a boost period. After the Boost period is activated the meter will display a
message: Activate with XX min
• Extend Boost:
Choose one of the possible available periods: 15, 30 or 45.
Use "NEXT" button to navigate between options.
Use Long press on "SELECT" button to extend the boost period. After the Boost period is extended the meter will display a
message: Extend with XX min
• Cancel Boost:
Use Long press on "SELECT" button to cancel the boost period. After the Boost period is cancelled the meter will display a
message: Boost cancelled
Entries in the Boost Log will be made for:
• Every time the Boost Functionality is Activated including Start and Finish Time
• Every time the Boost Functionality is Cancelled including Start and Finish Time (both values are the same)
• Every time the Boost is Extended including Start and Finish Time
24.5. ALCS Event Log
Entries in ALCS Event Log are triggered by the following actions:
• A switch in Auxiliary Load Control Switch Calendar
• On receipt of a Request Control of HAN Connected Auxiliary Load Control Switch command (this represents
the command received by the meter from HCALCS)
• On receipt of a Reset HAN Connected Auxiliary Load Control Switch [n] State command (Give control back to
Calendar)
• On receipt of a Set HAN Connected Auxiliary Load Control Switch [n] State command (Open or Close)
• execution of Test Auxiliary Load Control Switch [n] command
All commands, except the third one (Revert to Calendar), have as a result two entries captured in the ALCS event log
(Revert to Calendar triggers three entries).
