Gecko IN.YJ3 V3 Control Box  tech sheet

The Gecko in.yj-3-V3 control system, the successor to the V2 version, is designed for small spas, offering enhanced functionality and greater flexibility. While maintaining the core features of its predecessor, the V3 version introduces LED indicators for troubleshooting and integrates the in.mix system for advanced light management.

This system is paired with the heat.wav.yj heater and comes equipped with three 230V relays, indicated by the number "3" in its name, allowing it to manage up to three spa components (note that a two-speed pump requires 2 relays).

Features:

Compact Design: The in.yj-3-V3 is exceptionally compact, making it perfect for tight installation spaces. It can even be mounted in a "portrait" orientation, adding versatility to its placement.

Common Relay Configurations:

A two-speed pump and a single-speed pump or blower
A circulation pump and a two-speed pump
One circulation pump and two single-speed pumps
A circulation pump, a single-speed pump, and a blower
A circulation pump can be paired with three single-speed pumps (or two single-speed pumps and a blower) if the pump runs 24 hours a day.

The system also includes:

12V DC output for a projector
230V output for an ozonator
Auxiliary 230V output for additional accessories, such as a music system
Communication ports: One for the main keyboard and additional ports for an auxiliary keyboard (e.g., in.k300), in.stik, or in.touch2.

Configuration is straightforward, done through the keyboard by selecting one of the pre-programmed options. If you have any questions about the setup or specific configurations, feel free to contact us for assistance.

Power Supply Options: The system is pre-configured for single-phase power but can also be configured with two phases, allowing you to distribute spa components across two circuits. For specific power configurations, please consult the guide or contact us during your order placement.

Buying and support guide

We supply the Gecko YJ3 Control Pack ( direct replacement for Gecko YJ2 Control pack ) with clear specs and UK support. Before you order, check it suits your spa model, size, connector type, power supply and access. This helps you avoid delays and returns.

Replacing a part? Match it to your spa's model and year where you can. For pumps, control packs, heaters, jets, covers, filters, topsides and plumbing, check the part number and connection type. Compare delivery time, warranty and support as well as price.

Running costs matter as much as the price you pay. Energy use, insulation, cover condition, filters and water care all affect long-term value. Replacing worn parts early and keeping the water moving and filtered can save on repairs.

Looking for a whole new tub rather than a part? Compare hot tubs, swim spas and saunas by seating, hydrotherapy, who will use it and the space you have.
