$1,998.99 installation and unit.

The Pensar 1000 firmware now supports APS Rate Schedule ECT-2. 

Real Time Clock/Timers:  Allows all or some controlled loads to be scheduled off or on, during preselected hours.  If your utility company offers a discount for demand during off peak hours, a timer can be used to increase your demand limit precisely during those hours.  In the event of a power outage the correct scheduling and time will be maintained by a battery backup.

Digital Display:  Displays the last period average, current demand, demand limit, peak period average, and override status.

Adjustments in Tenths Of Kilowatts:  Allows you or a technician to make changes and receive critical information to the 10th of a kilowatt for settings up to 10 KW.  (Settings over ten KW may be adjusted in 1/2 kilowatt increments).

Permanent Memory:  State-of-the-art electrically erasable programmable memory (EEPROM) is used to preserve critical information in the event of a power interruption.  No batteries are required.

Programmable OFF/ON Times: Adjustable off and on times, from on to 15 minutes, add efficiency and flexibility.  Minimum off and on times are typically factory set at 6 minutes for compressor protection, but can be adjusted to fit different applications.

Circuit Override:  Allows you or a tech to temporarily change the priority loads (1 or more) for a period of 6 mins to 99 hrs.  This may be quite helpful if you want to use a specific appliance which is currently shed (not powered on).  You can also choose if you want to disable a load during this cycle.

Data Lock:  Will protect stored data from being accidently changed.

Choice of Manual or Automatic: 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.

Individual Control Points:  8 control points are available.  Individual points of control offer the greatest convenience and flexibility.  Up to sixteen loads may be controlled with the use of optional relays – two loads per control point.

Flexible Priority Strategies:  You can assign up to eight levels of priority to each point of control.  Unlimited combinations of rotating/fixed load priority groups are selectable so it can fit the needs of every household.

Choice of Open Frame or Enclosed Relays:  The Pensar 1000 comes standard with industrial quality open frame or enclosed relays.

Programmable Demand Averaging Period:  Averaging periods can be adjusted to 60, 30 or 15 mins to match your utility company.  This will allow for the greatest amount of efficiency in control strategies.

Individual Testing:  Each load controller unit is carefully tested and burned-in for performance and reliability.
