KW Monitoring/Load Shedding

KW Monitoring/Load Shedding

KW Monitoring

Standard

  • KW monitoring using either KW pulse meters, KW meters or current transformers.
  • Calculation of total energy used and current demand. The following KW calculations are performed and displayed: KW/hour, KW/day, KW/week, and KW/year.
  • Tracks highest demand for the day with time of occurrence.
  • High Demand Alarm
  • KW log records daily totals.

Options

  • Multiple circuits and separate control to match facility
  • Communications to power meters for additional power parameters

Load Shedding

Standard

  • Uses KW monitoring data.
  • Shutdown evaporators to maintain demand KW below user defined limits.
  • User programmable normal and fast response delays
  • Setpoint scheduling:
    • Four programmable setpoint groups (demand KW setpoint, normal bandwidth, control deadband, normal stage delay, and fast stage delay).
    • Three daily schedules each with eight time slots.
    • Manual override provided for schedule number and setpoint group.
  • Ability to enable/disable each zone for load shed and prioritize enabled zones.
  • Looks at zone temperature compared to setpoint and shuts down closest zones first
  • If a zone warms up to user defined limits it will be restarted.

Options

  • Ability to add non-refrigeration equipment to the shed list and prioritize.
