The beauty of the C5 control series is its simplicity. All the components from the relays to the fuses are located right on the board. This is nothing new, except that the C5 series accomplishes this without having high voltage run through the board. With this unique design, you get the convenience of an all-in-one board with the safety and longevity of low power electronics. This control system is set up for a 240v power supply. The control come standard with primary and secondary pumps wired for 240v, light is wired for 12v, and all other components (blower, ozone, circulation pump, stereo/aux) is wired for 120v. Voltages of these controls may easily be changed by moving the neutral wires at the power block in the control as needed. (see instruction manual for wiring configuration)

The T8 Topside

The new T8 Command Center from United Spas features the latest breakthroughs in our patent-pending Spa-Touch switching technology that greatly enhances the tactile feel of pushing the topside's buttons and overall usability. The new T8 topside is the most user-friendly and easy to use topside we've manufactured yet!
You'll immediately notice the T8 topside is larger, and features much larger and brighter 4-digit LED display then the T7. Internally, the T8 also features an internal clock, which keeps track of time so that the filtration cycle(s) can easily be set to any time of day. The time can be displayed during normal operation, or can be hidden and used only for filtration timing. Just like the T7, the T8 works in conjunction with the latest C5 series control boxes to create a full-featured spa control that can be configured for use in 48 different equipment configurations, making it a suitable replacement system for most spas currently on the market.
Safety, built-in

The C5 series of controls are one of the industrys first controls to be fully tested and approved under the latest editions of UL testing requirements for the United States, and CSA testing requirements for Canada.
Spa Control Systems should be installed by a licensed electrician, Hot Tub repair technician or individuals with the basic knowledge of electrical safety and knowledge of electronics.
