Independent Supplier & Replacement Part Notice
We are an independent parts supplier and are not affiliated with, sponsored by, or endorsed by Watkins, Hot Spring, Caldera, Tiger River, or Solana. These names and their part numbers are used only to identify compatibility.
We offer replacement parts as alternatives to spa-branded parts. When this listing identifies a part as the same original-manufacturer replacement, it is supplied under the component manufacturer’s branding and part number, which may differ from the Watkins or spa-brand label and number. Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.
Retro-fit for Watkins tubs such as Hot Springs and Caldera that utilize the small low flow circulation pump and the No Fault 1500 and No Fault 4000 heaters only. 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).
This model also requires one breaker with two hot lines, neutral and ground. If your system has two breakers (30 amp and 20 amp) you can either swap over to one 50 amp breaker and redo your electric or call us for further assistance.
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.
