I'm using a two-pin fan and the alarm goes off every time I press the force button?!

When you use a two-wire fan with the DD5, you must make sure that you disable the fan monitor before beginning operation. Otherwise the monitor keeps looking for the fan signal, and when it does not receive one, it then sounds the alarm to alert you. 

To disable the fan monitor, press the SET Button until Fan X appears on the screen. Next to Fan X it's either EN for Enable or DIS for Disable. If the screen reads EN, press the Up or Down button to change it.
