I would like to reset the condenser water supply temperature via Python Plugin. I have experience with resetting following values: Schedule:Compact > Schedule Value; Pump > Pump Mass Flow Rate ; Fan > Fan Air Mass Flow Rate

What I did: I have found nice examples of condenser water reset in E+ Example folder (files CoolingTower_VariableSpeed_CondEntTempReset.idf CoolingTower_VariableSpeed_CondEntTempReset_MultipleTowers.idf CoolingTower_VariableSpeed_IdealCondEntTempSetpoint.idf CoolingTower_VariableSpeed_IdealCondEntTempSetpoint_MultipleTowers.idf

Problem: All these examples use SetpointManager:CondenserEnteringReset or SetpointManager:CondenserEnteringReset:Ideal object to reset the temperature. The issue is I don't know what E+ variable to use to be an actuator handle.

I tried to use OutputVariable as a handle but failed

self.api.exchange.get_actuator_handle(state, "Output:Variable", "System Node Setpoint Temperature", "Condenser Tower", "Outlet Node")

returns -1 (=> it failed)

Could you help me to find right solution for resetting the condenser water temperature?

EDIT: Copying relevant sections from original file CoolingTower_VariableSpeed_IdealCondEntTempSetpoint.idf (see installation/ExampleFiles) where I want to reset the condenser tower outlet temperature.
