Retro-fit for Watkins tubs such as Hot Springs and Caldera that utilize the small low flow circulation pump and the No Fault 6000 heater. The Control System is designed to work with the Original No Fault Heater in your Hotspring Watkins tubs. In other words you would use the original heater, sensors, circulation pump and jet pumps. You will be changing the spa pack and adapting a new topside control panel. The spa pack supports Pump 1 single or 2 speed, a secondary single speed pump, circulation pump and a 12 volt light (May need to adapt if your light is 115/120V Flood light style)

Keep in mind that this is a retro-fit. There may be adjustments that need to be made to fit this unit, as many of these spas have a very tight equipment panel. But this system will save you hundreds over the original equipment.

The HS1000 System includes complete control, topside control panel, black out plate and cords / plugs.

If you have the No Fault 4000 or No Fault 1500 we have an alternate system you can use here but this one would work too: Pack Replacement for some Hotspring Watkins Spas with No Fault 1500 and 4000 Heaters Only - Use this with the current heater (1) or (2) Pump
