Setting a Boolean as a field of an object from another script

I saw this question asked some times but no one correlates to mine. I see people using the GetComponent() function but this one should work too.

First I receive a Bool value from a toggle button and assign it as a field of the object 'hydro':

hydroControl.cs

using UnityEngine;
using System.Collections;
using Assets.Code.PowerPlants;

public class hydroProwerControlPanel : MonoBehaviour {
private HydroElectric hydro;
public bool t1;

void Start () 
{ 
    t1 = true;
}

public hydroProwerControlPanel (){
    hydro = new HydroElectric();
}
public void turbine1State (bool t1) {
     hydro.t1Bool = t1;
}

Then I have the object where this bool change should be recognized and sent as an output, but it doesn't:

using System;
using UnityEngine;
namespace Assets.Code.PowerPlants
{
    public class HydroElectric
    {
        public bool t1Bool;
        float turbina1;

        public float prod;

        public HydroElectric ()
        {   
          t1Bool = true;
          prod = 0f; 
        }

        public float ControlPanel ()
        {
            turbina1 = t1Bool ? 1.5F : 0;   

            prod = turbina1 ;
            Debug.Log (prod);
            return prod;
        }
    }
}

As requested, this is where the function ControlPanel() is called:

using System;
using UnityEngine;
using UnityEngine.UI;
using Assets.Code.PowerPlants;
namespace Assets.Code.Interfaces
{

public class PlayLevel1 : MonoBehaviour 
{
private HydroElectric hydro;
public Text producao;

public PlayLevel1 ()
{
    hydro = new HydroElectric();
}

public void OnGUI()
{
 producao.text = hydro.ControlPanel().ToString();          
}
}
}

Do you have any idea why does this Bool does not get updated? Any help appreciated.
