🔌 Gecko IN.YT-7 Control Box (Software 351) 3kW – Pre-Configured Multi-Pump Spa Controller

High-capacity spa controller with specific software configuration for three dual-speed pumps and 3kW heating.

📋 Product Overview

⚠️ ATTENTION: THIS CONTROL BOX HAS SPECIFIC CONFIGURATIONS. Please download the configuration chart before ordering. If you require the generic IN.YT-7 with 4kW heater, please see model BX-YT700.

The Gecko IN.YT-7 Control Box (Software 351) is a high-capacity spa control system pre-configured with specific software settings for particular spa installations. Unlike the standard IN.YT-7 with 4kW heater, this variant features a 3kW heat.wav heater and is designed to manage three dual-speed pumps, an optional circulation pump, and multiple accessory outputs.

With seven configurable outputs, Software 351 configuration supports extensive pump control including three main dual-speed pumps, circulation pump capability, ozone generator support, and two direct outputs for audio/video equipment. The integrated 3kW heat.wav heater with Gecko’s patented in.flo electronic dry-fire protection ensures safe, efficient heating.

The Y Series architecture provides exceptional flexibility with single-phase, dual-phase, and three-phase electrical support. The IPX5-rated watertight enclosure and industry-standard AMP connectors ensure reliable installation in demanding spa cabinet environments.

This control box is intended for like-for-like replacement or specific OEM applications requiring Software 351 configuration. Always verify compatibility with your existing system configuration before ordering.

❓ Frequently Asked Questions

Q: What’s the difference between this and the standard IN.YT-7 (BX-YT700)? A: This model (Software 351) has a 3kW heater and specific pre-loaded software configuration. The standard BX-YT700 has a 4kW heater and generic software. Always verify your requirements before ordering.

Q: How do I know if Software 351 is right for my spa? A: Download the Software 351 Quick Card document from the Downloads section. This shows the specific output assignments and configuration. Your spa manufacturer or installer can advise on compatibility.

Q: Can I change the software configuration? A: Yes, using an in.stik device. However, the unit comes pre-loaded with Software 351 which is why it’s sold as a specific configuration option.

Q: Why is the heater 3kW instead of 4kW? A: Different spa configurations have different heating requirements. The 3kW heater (2.8kW at 230V) is sized appropriately for the pump and accessory load defined in Software 351.

Q: Do I need a qualified electrician? A: Yes. All spa control box installations must be performed by a qualified electrician in compliance with BS 7671 and Part P regulations.

Q: What topside panels are compatible? A: All Gecko IN.K series keypads are compatible, including IN.K200, IN.K300, IN.K450, IN.K500, IN.K600, IN.K800, and IN.K1000.

Q: Does this include a topside panel? A: No, the control box with heater tube is sold separately. Topside panels must be purchased separately.

Q: Can I control my spa remotely? A: Yes, with the optional in.touch module (sold separately).
