The Most Versatile Control Series in the Industry
The C series of electronic controls is our flagship line, our three main configurations make the C series one of the most versatile in the industry.
Featuring our fifth generation bespoke B series of printed circuit boards.
The new B series board features ‘zero-crossing’ technology. This means that the relays are now only engaged at the optimal zero crossing of AC power, which is easier on the relays, and easier on the components in the spa.
Every trace on these boards have been carefully engineered, with low voltage circuitry separated from high-voltage circuitry, and utilizing solid brass bars instead of printed copper traces for high voltage power. This unique design ensures the safety and longevity of our control systems.
C series control boxes ship with our dual-voltage transformers. The days of swapping out transformers to switch between 240V and 120V power hook-up are over! With the C series, incoming power voltage can be switched by moving the transformer’s 2-pin power selector plug between the control board’s 120V and 240V receptacles.
The C series controls come out of the box ready to operate at 120V or 240V (3-wire or 4-wire), at 50Hz or 60Hz, and configurable to 40 different hardware configurations. That makes any C series capable of operating almost any spa, anywhere in the world, right out of the box!
C series Models
There are 4 different models in the C Series, all feature the same electronics, but offer different heater configurations.
B box
The most common unit is the C5-C6B Bottom Heater, which features 15″ long 2″ flow-thru style heaters mounted inside the bottom of the box.
Remote heater
There is a model with a ‘remote’ heater, the C5-C6R, which features the same 15″ long 2″ flow-thru style heater on a 4′ cable for remote heater installations.
Low flow heater
There is the C5-C6G which is designed for use with external gas heaters, and the C5-C6LF, which is designed with a special low-flow heater for use on spas with small circulation pumps.
Each C series control model is available with either the entry-level T7 Command Center, the T8-S Command Center.
