Displays the demand limit, current demand, last period
average, peak period average, and override status.
Real Time Clock/Timers:
Allows some or all controlled loads to be scheduled on or off
during preselected hours. If your utility offers a discount on demand
during off peak hours, a timer may be used to increase your demand limit
during those hours. In the even of a power outage the correct time and
scheduling will be maintained by a high quality battery backup.
EEPROM (electrically erasable programmable memory) is used to preserve
critical information in the even of a power interruption. No batteries
Adjustments in Tenths Of Kilowatts:
Allows you to make changes and receive information to the
tenth of a kilowatt for settings up to ten KW. (Settings over 10 KW can
be adjusted in half kilowatt increments).
Allows you to temporarily change the priority of one or more
loads for a period of 6 minutes to 99 hours. This may prove quite
helpful if you need to use an appliance which is currently shed. You
may also choose to disable a load during this cycle.
Programmable ON/OFF Times:
Adjustable on and off times, from on to 15 minutes, add
flexibility and efficiency. Minimum on and off times are factory set at
six minutes for compressor protection, but may be adjusted to fit
Choice of Automatic or Manual:
You may choose to have your demand limit adjusted
automatically by the computer for seasonal changes, between a maximum
and minimum you select, or manually adjust it yourself at will.
Protects stored data from being inadvertently changed.
Flexible Priority Strategies:
You may assign up to 8 levels of priority to each control
point. Unlimited combinations of fixed and/or rotating load priority
groups are selectable to fit the needs of every household.
Individual Control Points:
Eight control points are available. Individual control
points offer the greatest flexibility and
convenience. Up to 16 loads may be controlled with the use of optional
relays (2 loads per control point).
Programmable Demand Averaging Period:
Averaging periods may be adjusted to 15, 30, or 60 minutes to
match your particular utility company. This will allow for the greatest
efficiency in control strategies.
Choice of Enclosed or Open Frame Relays:
The SYSTEM 1000 comes standard with high performance
industrial quality enclosed or open frame relays.
