satisfied also. If the parameter is set to Global, all metering points
are in essence 'added up' into one larger system treated and managed
globally. |
| Average Demand Extrapolation |
Obsolete, leave Disabled. |
| Active Cycle Demand Correction |
This parameter enables the active
cycle demand correction algorithm. |
| Demand High Threshold |

LMEX thinks should be in the OFF state. When set to OFF and ON,
both of the above are executed. When set to ON
Only (Operated Today), ON codes are sent to loads, which were
previously operated that same day, and LMEX thinks should be in the
ON state. When set to OFF Only (Operated Today), OFF codes are sent to loads,
which were previously operated that same day, and LMEX thinks should be in the OFF state. When set to OFF and ON
(Operated Today),
both of the above are executed only on loads which were previously operated
that same day. |
| Reinserting Time Of Day |
Specifies time of day when above activities
are to be performed. Several of these Reinserting Time of Day parameters are

parameter, thereby allowing different kinds of reinserting activities to
be executed at different times of day. |
| Reinserting
After Peak Period (Min, 0=Off) |
Specifies the number of minutes after peak
billing period expires LMEX is to initiate load reinserting cycle. If
set to 0 this option is disabled, and Reinserting Time of Day is used to
schedule the next reinserting cycle. Several of these Reinserting
After Peak Period parameters are
available, each being paired with its own Reinserting Method
parameter, thereby allowing different kinds of reinserting activities to
be executed at different times of day. |

Parameter specifies number of consecutive
load management cycles when metering point demand is higher than the high threshold for
the latter to be automatically raised to the observed demand reading. |
| Load
Management Strategy In Effect |
Identifier of load management strategy meant
to be in effect when Load Management Strategy Selection Method is set to
Manual (see below). |
| Load Management Strategy Selection Method |
Parameter specifies the method of controlling
which load
management strategy is in effect. If set to Manual,
above Strategy parameter specifies that strategy. If set to Demand,
