The control panel uses a main display to show the status of the Spa Control System and other LED messages. The main display shows which spa functions are active (light, jets, summer timer, locking features).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. The control head has the control thermostat, light dimmer, diagnostic LEDs and jet switches incorporated into it. 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.
