The Techmark CC4D-120 unit is used to control the hot tub/ spa pack from the hot tub top side. The unit has 2 buttons for the over lay but can have up to 4 buttons.

 

Please state 2 buttons, 3 buttons or 4 buttons when ordering!

 

When replacing your Gecko topside control panel, always choose the new replacement Gecko topside that matches that part number on your old topside. Do not choose a new topside panel based on appearance, some of them look very similar but may not be compatible
