Description
Gecko S-Class IN.XM2 Spa Control System is a legacy powerhouse designed to orchestrate a four-appliance spa setup with precision. While it has been discontinued by the manufacturer, this IN.XM2-based controller remains a compelling option for builders and seasoned spa owners who demand robust automation, a graphical topside, and flexible wiring configurations.
Flexible four-appliance orchestration
Configure and sequence multiple devices to match your spa’s layout and performance needs. Appliance configurations include:
- Appliance #1: 1-speed pump or 2-speed pump, 115/230V
- Appliance #2: 1-speed pump or 2-speed pump, 115/230V
- Appliance #3: 1-speed pump and blower (115/230V), with no second device in some setups
- Appliance #4: 1-speed pump and blower (115/230V)
In addition, the system supports a range of module configurations labeled P1/2/3/Cp/Bl/Oz/L/Ac for pumps, circulator, blower, ozone, lights, and auxiliary components, giving you granular control over each element.
Power, temperature, and reliability
- Supply voltage: 115V or 230V — designed to fit typical spa electrical installations
- Remote heater support with two wattage options: 1.0 kW or 4.0 kW
- Circ pump ready: Yes, for efficient water circulation

Who benefits from the IN.XM2 S-Class system
This Gecko system is ideal for homeowners restoring or upgrading a spa that already relies on multi-appliance setups, as well as installers who need a flexible, scalable controller with a graphical topside and modern connectivity. It’s especially well-suited for:
- Spas requiring four distinct appliances to manage pumps, blowers, and heaters
- Projects that will leverage remote monitoring and Wi-Fi-enabled control
- Installations where a fiber optic backbone ensures dependable data transmission across long cable runs
Practical considerations and tips
- Because this is a legacy Gecko system, verify compatibility with any existing spa components and the availability of replacement parts or service support in your area.
- Plan for a 115V/230V supply in the same enclosure and confirm wiring requirements match the chosen heater wattage (1.0 kW or 4.0 kW).
- Take advantage of the in.k600 Graphical Topsides for intuitive navigation and quick access to pump speeds, heater setpoints, and light/blower controls.
- With Fiber Optic and Wi-Fi compatibility, consider routing fiber where possible to maximize signal integrity and remote accessibility.
