The EMS Application Guide description for actuator Plant Component, On/Off Supervisory is incorrect. It should read:
Setting the value of this actuator to 0.0 directs the component’s water flow rate to shut down regardless of what other controls indicate. Any other component on the same branch will also be shut down. Setting the value of this actuator to any value <=1.0 sets the current load for this component to the actuator value times the component maximum operating capacity which is the nominal capacity multiplied by the maximum part load ratio.
So the units for this actuator should be [fraction], not [W]. A new issue has been posted to fix this and the docs.
If I am following correctly, the baseboards will need a high zone thermostat setpoint so that they will accept all of the heat delivered by the boiler.
Finally, ThermostatSetpoint:DualSetpoint only works for dual-purpose loops such as a water loop heat pump. The upper setpoint is used as a cooling setpoint and the lower setpoint is used as a heating setpoint. It will not set an on/off range for a boiler loop.
