I'm tying to write an OpenStudio measure to add a HeatExchangerAirToAirSensibleAndLatent object to an outdoor air system attached to a unitary system on an air loop. The engineering reference for the heat exchanger indicates that I need to add a SetpointManagerScheduled on the unit’s supply air outlet node. I'm having trouble writing the code to place the setpoint manager on the correct node as there doesn't seem to be a method to identify the proper node. I'm looking for suggestions on how to find this node in the measure. Also, any advice on creating the schedule for this setpoint manager would be appreciated.
Here is the air loop as it stands currently:
