OpenStudio now takes care of these "intermediate" setpoint managers for you if you don't provide one. As long as there is an SPM on the last node (supply outlet node) OpenStudio will either clone that SPM or insert an SPM mixed air depending on the fan placement detected by OS.
You might want your ERV to control to a different temperature than your supply outlet control point, in that case you'd want to insert a custom SPM like SetpointManagerScheduled, but to keep things simple I'd just skip adding a SPM and let OS do its thing. Eric's answer is right on if you don't want to go with the OS defaulting.
