The selection options for Economizer Damper(s) are:

  • Common Proportional Mixed Air Damper Output

  • Packaged Economizer Enable (BO)

  • Economizer Suitability

    • Network Command

    • Enthalpy Switch (BI)

    • Outdoor Air

      • Dry Bulb Temp Economizer

      • Temp & Enthalpy Economizer

  • Mixed Air Damper Minimum Position Reset by CO2 Sensor

    • Use Zone CO2 Sensor

    • Use Return CO2 Sensor

  • Reduce Outdoor Air on Low Temperature

The Reduce Outdoor Air on Low Temperature selection enables logic that reduces the intake of outdoor air when the Mixed Air Temperature is low. This outdoor air intake reduction is accomplished by modulating the outdoor dampers closed. The control logic for the low limit strategy is embedded directly into the Output Control modules and activated simply by connecting the appropriate setpoint and process variable. The logic takes precedence over all logic other than Emergency Modes.
