On editing and retrieving a record in angular my checkbox is showing checked only for both Y and N

This is my html. I'm retriving data using ng model. Suppose if i have record with checkbox value N. on clicking edit record, it should show empty checkbox right ?? but as per my code the checkbox showing checked constantly for both Y and N records.

<form [formGroup]="addTermForm">
                        <div class="container">
                          <div class="row ">
                            <div class="col-xs-6 col-sm-6 col-md-6 col-lg-6">

                              <input type="text" class="form-control" placeholder="Enter rule"
                              formControlName="RuleName" 
                              [(ngModel)]="termDetails.RuleName" [ngClass]="{ 'is-invalid': submitted &amp;&amp; addTermForm.controls.RuleName.errors }">

This is my ts file for retriving data from service. Please help me with the checkbox. It should show unchecked for a record that is having value as N. as of now it is showing values as checked for both Y and N records. is there a issue with ngmodel and checkbox ?? because when i use the same for radio buttons it is working well.

export class EditSystemDefinedComponent implements OnInit {

  addTermForm: FormGroup;
  submitted = false;
  loading = false;
  Id: number;
  public globalResponse: any = [];
  termDetails: any = [];

  // public editTerm: any = [];
 
  constructor(
    private formBuilder: FormBuilder,
    private router: Router,
    private route: ActivatedRoute,
    private termSrvc: ApiService
    ) 
    {
      this.route.queryParams.subscribe(params => {
        this.Id = params.Id;
        console.log(this.Id);
   });
   }

  ngOnInit(): void {
    this.termEditForm();
    this.addTermForm = this.formBuilder.group({
      RuleName: ['', [Validators.required, Validators.pattern('[a-zA-Z# ]*')]],
     // Dealer_Id: ['', [Validators.required, Validators.pattern('[0-9]*')]],
      Type:  ['', [Validators.required]],
      Status:  [],
    });
   }

   termEditForm(){
    this.termSrvc.getIncentiveTermsById(this.Id).subscribe(
      response => {
        this.globalResponse = response;
        this.termDetails = this.globalResponse.response[0];
        console.log(this.termDetails);
      });
  }


  
 
  statusValueChange($event: any) {
    this.addTermForm.controls['Status'].setValue($event.target.checked ? 'Y' : 'N');
    console.log('form values:', this.addTermForm.value);
  }
