review recommendations for premium western economizer
Review Recommendations for Premium Western Economizer
  • Primary sensor control location
  • Two-stage thermostat & coordination
  • Differential dry-bulb outside air changeover
  • Adequate air flow and exhaust relief
  • Ventilation control
  • Quality Assurance

Premium Ventilation

desired sequence
Desired Sequence
  • Min OSA ventilation during heating
  • Use ventilation before cooling
  • Use full OSA vent with cooling coil
  • Lock out or Change over from ventilation to minimum when OSA too warm

Premium Ventilation

premium ventilation
Premium Ventilation
  • Start with a Western Premium Economizer
  • Upgrade the Economizer module with
    • DCV capable economizer control module
    • CO2 Sensor; Min air set to 0% = leakage
  • Add variable speed fan motor
    • Full (or near full) speed in heating or cooling
    • Low (30%) speed in idle mode

triple the savings
Triple the Savings
  • Premium Economizer Savings, plus
  • Fan savings when not heating or cooling
  • Savings during warm-up by reducing ventilation when not occupied
  • Ventilation heating and cooling savings when building not fully occupied
  • No need to set and measure outside air minimum
