HITACHi Air Conditioner green light turn off

Since last year I have a HITACHI Air Conditioner and the technician told me to clean the filters every two weeks, but he didn't mention anything about the green led. So after a while, this green light turned on, I noticed it has something to do with the filters so I have cleaned them hoping it has some sensor and will turn off automatically. But it didn't. Later I found you have to press the AUTO SWING from the remote while the unit is off. And after 200 hours of functioning it will turn on again to remind you about cleaning the filters.

Mass kill processes in MySQL "show processlist"

So your server load is high you did "SHOW PROCESSLIST;" and you noticed many slow queries and you want to kill them.
If the list is too long to do it manually, you may want to try this way:

<?php

include("mySqlClass.inc.php");

$serv="localhost";
$user="root";
$pass="YOUR_PASS";
$database="SOME_DB";


$link = new mySqlClass();
$link->Connect($serv,$user,$pass,$database);
$result=$link->SqlQuery("SHOW FULL PROCESSLIST");
while ($result->NextRow()) {
    $process_id=$result->field["Id"];
    if ($result->field["Time"]>200) $link->SqlQuery("KILL $process_id");
}   

?>

and the mySqlClass.inc.php:

<?php

class mySqlClass {

  public $query_count;
  public $query_time;

  private $database;
  public $link;
  private $db_connected;
