Description
Gecko MSPA Circuit Board — Model 9920-200459
The Gecko MSPA Circuit Board is the smart, compact control hub that synchronizes every vital function of a spa or hot tub system. With dual outputs and a robust 240V power profile, this board coordinates pumps, heating, blower, ozone, lighting, and optional circulating pumps so your spa delivers consistent comfort with every session.
Why this Gecko MSPA board stands out
- Two outputs for precise pump management — Pump 1 runs at 2 speeds (240V) and Pump 2 runs at a single speed (240V), enabling efficient water circulation tailored to different spa zones or user preferences.
- Integrated accessory power — Ready to drive your blower, ozone generator, and lighting, all from a single, reliable controller.
- Optional circulating pump support — Circ. Pump can be configured at 2400V to optimize water movement and thermal distribution.
- Clear diagnostics with no stray code — The display is designed to avoid unnecessary error codes, simplifying troubleshooting when service is needed.
- Flexible lighting and heating integration — Light output (1-12V) and a horizontal heater assembly (2-1/2", 5.5kW) are seamlessly controlled, reducing setup time and potential miswiring.
- Durable connectors for reliable installation — AMP Connector ensures solid, repeatable power connections essential for long-term spa reliability.
Ideal use cases
- Replacing a failing spa control unit in Gecko-equipped systems to restore multi-zone pump control, heating, and auxiliary features.
- Upgrading older spa configurations to independent dual-pump operation for better water turnover and energy efficiency.
- Installing a consolidated controller in new or retrofit projects where a single board must coordinate pumps, blower, ozone, lighting, and heater.
- Service technicians seeking a direct-fit MSPA replacement that aligns with existing Gecko components and AMP connectors.
Compatibility, installation & practical tips
Model MSPA with Manuf# 9920-200459 is built around a 240V power footprint and two outputs, making it a logical replacement for Gecko spa systems that rely on separate pump and accessory circuits. When installing or replacing:
- Ensure the power supply matches the 240V requirements for pumps, blower, ozone, and circ pump options.
- Verify AMP connectors are seated firmly to prevent arcing and intermittent shutdowns.
- Confirm heater orientation (Horizontal) and rated capacity (5.5kW) align with your system’s heating needs and safety clearances.
- If diagnostics show no error code on display, double-check wiring order and accessory wiring to confirm all outputs are functional.
