Replacement for all 2001-2008 Hot Spring spa models, this control head is located behind the frontside control panel bezel. It is connected to the IQ 2020 Control Box with what looks like a computer ribbon. When a button is pressed on the frontside control panel bezel, that button is actually pressing on tabs located in specific areas of this control head. Those tabs in turn press on pressure points on the small circuit board inside the control head to activate a specific function. The control head is also where the thermostat circuitry is located as well as the LED readout of temperature and various icons.
