Setting up the room unit (ED-RUD)



While not configured the screen of the room unit doesn't show any control buttons or information. However the screen is light and it can be visible around the edges.


To enter the configuration menu of the ED-RUD simultaneously touch and hold the area on the screen of the "/\" and "\/" buttons. Release once the four digit number start flashing (e.g. 0022)


Use the "/\" and "\/" buttons to navigate parameters P001 ... P009 and change the values if necessary. Use "Power" button to enter parameter and to confirm the new value.
