Setpoints and related data

The setpoints and related data include the following items:

  • Low ambient economizer minimum position (LowAmb-MinPos)
  • Low ambient economizer setpoint (LowAmb-Sp)


The low ambient economizer minimum position overrides all other minimum position functions.

When the control is in the occupied mode, the FAN output is energized, and the operational OAT is below the low ambient economizer setpoint, the economizer is positioned to the low ambient economizer minimum position. When the Operational OAT is equal to or above the low ambient economizer setpoint, it exits the low ambient economizer setpoint mode.
