🔧 Introducing the Gecko Universal HQ YE‑5 System
If you've got a low-flow hot tub or spa and want a straightforward, versatile control upgrade, the Gecko Universal HQ YE‑5 system is a game changer. This all-in-one bundle includes:
- Gecko in.ye‑5 controller pack, part of Gecko’s Y series
- 3 kW slide‑through heater (low-flow compatible)
- Gecko IN.K450 keypad, top-side user interface
- Amp-cord harness, flow detector, 12 V LED lighting kit, plumbing adapters & fittings
What It Does & Why It Matters
This system is a versatile upgrade solution, especially ideal for low-flow setups. Here’s why:
- Engineered for low water flow: The slide-through heater is designed to work at a minimum flow of 18–20 GPM, making it compatible with low-volume spa systems where typical high-flow heaters fail.
- Five configurable outputs: Power and control up to five devices—dual-speed pumps, single-speed pumps or blower, circulation pump, ozone, and lighting—all from one unit.
- Solid-state flow detection: Accurate, reliable detection without pressure switches.
- Safe heating tech: Titanium elements, overheat protection, freeze control, and smart diagnostics ensure efficient, safe operation.
- Energy saving + convenience: Supports programmable cycles, dual voltage input (115/230 V), and 12 V LED lighting.
Inside the Kit: A Ready-to-Install Package
Each system bundle includes everything you need for a retrofit or full upgrade:
- in.ye‑5 control box with 5 relays
- 3 kW low-flow slide-through heater
- IN.K450 keypad (7-button LCD interface)
- Amp plug-and-play harnesses
- 12 V LED light kit
- Flow detector assembly with plumbing adapters
- Mounting brackets, fittings, and instruction manual
Pump Compatibility & Flow Rate Requirements
The YE‑5 supports a wide range of pump configurations:
- Pump 1 & Pump 2: Dual-speed pumps (115 V or 230 V)
- Pump 3 / Blower: Single-speed pump or air blower
- Circulation Pump: Dedicated output for a continuous low-speed pump
- Ozonator & 12 V Lighting: Additional low-voltage outputs
Flow Requirements:
- Heater flow rate: Minimum 18–20 GPM for safe heating and accurate flow detection
- Circulation pump flow: Must also deliver at least 20 GPM if used
- Suitable pumps include Waterway Iron Might or Aqua-Flo CircMaster
- Avoid underpowered pumps like Laing E10 or Tiny Might—these do not meet minimum flow specs
Gecko IN.K450: Simple, Clear Control
The IN.K450 keypad features a user-friendly 7-button layout with backlit LCD screen. You can operate jets, blower, light, filter cycles, and heating directly from the spa. It’s compact, modern, and designed for straightforward day-to-day use with built-in diagnostics.
Installation Tips
- Power off completely before starting. Verify correct breaker size and voltage (115 V or 230 V).
- Mount the control box on a dry, vertical surface above water level.
- Install heater and flow detector inline with correct flow orientation.
- Connect pumps and accessories using the labelled AMP harnesses provided.
- Install the keypad using the supplied gasket; plug into the panel port.
- Prime and test the system before applying full power—ensure the spa is fully filled and bled of air.
Perfect for Low-Flow Systems
This system is ideal for:
- Spas with smaller plumbing or low-volume designs
- Tubs using efficient circulation pumps
- Older installations needing a reliable, modern control solution
- Any setup that previously triggered flow errors or heater cutouts
With the YE‑5, you get low-flow-compatible heating, safe and configurable outputs, and precise control—all in one compact package.
