HVAC Control Logic

is it possible to model a control logic as follows in either OpenStudio or DesignBuilder (I assume it's the same logic since using E+):

  • if outdoor air temp is below 10C, the chiller is shut down;
  • if outdoor air temp is above 10C, the chiller is used to provide 13C chilled water

in DesignBuilder, the "setpoint manager" has only 2 types - "scheduled" or "outdoor air reset" in the water loop. when using "outdoor air reset", only setpoint at outdoor low temp and high temp can be defined. How to achieve the control logic above?
