hey im back, when i run this code none of the default values are correct?

#include <EEPROM.h>
// __attribute__ ((packed)) is to force the compiler to use the minimum required memory to represent the type
// see https://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/Type-Attributes.html
struct __attribute__ ((packed)) _paramS {
  unsigned long minimumT;
  unsigned long maximumT;
  unsigned long maximumA;
  unsigned long maximumB;
  unsigned long t1ontimeDAY;                       /////
  unsigned long t1offtimeDAY;  
  unsigned long t2ontimeDAY;                       /////
  unsigned long t2offtimeDAY; 
  unsigned long t3ontimeDAY;                           /////
  unsigned long t3offtimeDAY; 
   
  unsigned long t1ontimeNIGHT;                     /////
  unsigned long t1offtimeNIGHT;  
  unsigned long t2ontimeNIGHT;                     /////
  unsigned long t2offtimeNIGHT; 
  unsigned long t3ontimeNIGHT;                         /////
  unsigned long t3offtimeNIGHT;
} myParamters;

const uint32_t keyword = 0xDEADBEEF;
const uint16_t keywordAddress = 0x00;
const uint16_t paramAddress = keywordAddress + sizeof(keyword);

void printParam()
{
  Serial.println(F("\n************* PARAMS *************"));
  Serial.print(F("Temp minn =\t")); Serial.println(myParamters.t1ontimeDAY);
  Serial.print(F("Temp maxx =\t")); Serial.println(myParamters.t2ontimeDAY);
  Serial.print(F("Temp max =\t")); Serial.println(myParamters.maximumB);
}

void saveParam()
{
  EEPROM.put(keywordAddress, keyword);
  EEPROM.put(paramAddress, myParamters);
}

void getParam()
{
  uint32_t tmpKey;

  EEPROM.get(keywordAddress, tmpKey);
  if (tmpKey == keyword) {
    EEPROM.get(paramAddress, myParamters);    // EEPROM was already initialized OK to read
  } else {
    // First run on this arduino, memory was never initialized. so establish default values
    myParamters.t1ontimeDAY = 1002001;
    myParamters.t1offtimeDAY = 1002002;
     myParamters.t2ontimeDAY = 1002001;
    myParamters.t2offtimeDAY = 1002002;
        myParamters.t3ontimeDAY = 1002001;
    myParamters.t3offtimeDAY = 1002002;
        myParamters.t1ontimeNIGHT = 1002001;
    myParamters.t1offtimeNIGHT = 1002002;
        myParamters.t2ontimeNIGHT = 1002001;
    myParamters.t2offtimeNIGHT = 1002002;
        myParamters.t3ontimeNIGHT = 1002001;
    myParamters.t3offtimeNIGHT = 1002002;
    saveParam();
  }
}


void setup() {
  Serial.begin(9600);

  getParam();  // first run will establish the defaults in EEPROM
  printParam(); // see what the values are

  myParamters.minimumT = 1002001;  // change one of the parameters
  myParamters.maximumB = 1002011;  // change one of the parameters
  saveParam(); // save it
  printParam(); // show it has been saved
}

void loop() {}

or is it that this part don't run unless there is a problem reading from eeprom?

  EEPROM.get(keywordAddress, tmpKey);
  if (tmpKey == keyword) {
    EEPROM.get(paramAddress, myParamters);    // EEPROM was already initialized OK to read
  } else {
