Aux Control Head

This part is a replacement aux control head for select Caldera hot tubs. The control head, located on the bar top, consists of an electronic board and housing with a conformal-coated moisture, resistant barrier. The control head serves as an interface between the control panel and the control box.

When the control panel is used to activate one of these functions, the control head registers the command and sends a signal to the control box, telling it to activate the chosen function. Compatible with 2009 to current Utopia series Caldera spa models.
