Boiler:HotWater Outlet setpoint

Boiler:HotWater,
Main Boiler,             !- Name
NaturalGas,              !- Fuel Type
ConstantFlow,            !- Boiler Flow Mode
1.0;                     !- Sizing Factor

  _boiler_outlet_actuator = api.exchange.get_actuator_handle(
        state, "System Node Setpoint", "Temperature Setpoint", "Main Boiler HW Outlet")
api.exchange.set_actuator_value(state, _boiler_outlet_actuator, 70)

I have the above definition: 1. Try to control the outlet water temperature of one constant speed Boiler:HotWater. However, it didn't work. Can you please provide any insights how to control the heating power from Boiler (For the entire building)?

Thank you!

Update:Aug 19, 2022. It turns out the _boiler_outlet_actuator defined in my python code has been used in the Setpoint:Manager. After deleting the Setpoint:Manager in the idf file, my strategy worked.
