♨️ Gecko IN.K336 Topside Control Panel (Without Overlay) – Compatible with Gecko in.ye5 Systems

Precision control for effortless hot tub management

📋 Product Overview

The Gecko IN.K336 is a 5-button topside control panel designed as a direct replacement for hot tubs running the Gecko in.ye5 spa pack system. This panel utilises Gecko’s proprietary in.link connection method, ensuring a secure and reliable interface between the topside and the control system.

Built for compatibility with a range of popular hot tub brands including Earth Spas and Master Spas, the IN.K336 supports up to 2 pumps, making it suitable for spas with both a circulation pump and a jet pump configuration. The panel features a compact yet functional design with dimensions of 182 mm × 75 mm, fitting neatly into the spa’s topside mounting position.

Please note that this topside panel is supplied without the overlay — the overlay must be purchased separately to complete the installation. This is ideal for customers who already have a functioning overlay or who require a different overlay configuration for their specific spa model.
