Controller is panel built-in design; it is fixed by clips when installed. 
1)  Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position. 
2)  Pull the fixing clip backwards (towards the back of the module) ensuring two clips 
are inside their allotted slots.   
3)  Turn the fixing clip screws clockwise until they are fixed on the panel.   
  Note: Care should be taken not to over tighten the screws of fixing clips.
