VDM LED & Pumps Control Module

Add Advanced 0 to 10V Control to Your Apex System

• Enables Apex control of compatible pumps and LED fixtures
• Seamless plug and play integration with any Apex base unit
• LED status indicator for simple troubleshooting
• Includes 3-foot AquaBus cable
• Dual AquaBus ports for flexible system expansion

The Neptune Systems VDM Module adds two 0 to 10V variable speed ports (each with two independent channels) to your Apex, allowing you to control compatible pumps and lighting systems through your Apex Fusion dashboard. Fine-tune flow with pumps and powerheads or program custom lighting schedules with select LED fixtures using the VDM’s analog control outputs.

Common Use Cases:

• Tunze Pumps: Control flow rates and pulsing modes on models like the 6105, 6155, and 6255 (Tunze to Apex interface cable required, sold separately. Not compatible with HUB Edition pumps)
• LED Lighting: Program dimming and spectrum changes on select 0 to 10V LED fixtures such as Kessil A80, A160, and older A360W models
• Custom Control Projects: Integrate with DIY equipment that uses analog 0 to 10V control input

Compatibility Notes:

• Requires a Neptune Apex base unit (A3, A2, or legacy Apex models)
• Compatible with many 0 to 10V controllable pumps and lights
• Does not support Neptune 1Link accessories or lights using digital/wireless communication protocols
• Interface cables for pumps and lights are not included and must be purchased separately
