Using OpenStudio (2.1.0) is it possible to set an Availability Schedule on an AirTerminal:SingleDuct:NoReheat object?

OpenStudio appears to be applying 'Always On Discrete' to the air terminal object's Availability Schedule Field.

My goal is to simulate an air handling unit which has a few zones operating to a monday to saturday while the rest of the zones on that AHU operate to a monday to friday schedule.

If that is not possible using OpenStudio, what are some options for achieving the same goal? i.e Different thermostats?

You can do this with the OpenStudio API. Make a schedule ruleset with a name (e.g. "My Schedule") and then run this script:

zones_to_change = ["Thermal Zone 1","Thermal Zone 2"]

#your new availability schedule
my_schedule = model.getScheduleByName("My Schedule").get 

#get thermal zones in the model
zones = model.getThermalZones 
zones.each do |zone|
  zone_name =
  if zones_to_change.include? zone_name
    #returns array of zone equipment
    zone_equipments =
    zone_equipments.each do |equip|
      #checks if the object is of this object type
      if !equip.to_AirTerminalSingleDuctVAVNoReheat.empty?
        air_terminal = equip.to_AirTerminalSingleDuctVAVNoReheat.get
