The TrolMaster DSP-1 is a plug-and-play, addressable timer relay for the Hydro-X and Aqua-X control systems. It provides scheduled or cyclic ON/OFF control for connected equipment up to 10A at 100–240VAC, including pumps, supplemental lighting, CO₂ accessories, exhaust/intake fans, and other time-controlled loads. On Aqua-X systems, it can also function as a master pump controller, automatically activating the pump whenever a 24VAC irrigation zone operates.

Key Advantage: The DSP-1 adds an independently addressable 10A scheduled outlet to an existing Hydro-X or Aqua-X network, eliminating the need for a separate standalone timer. Its additional Aqua-X master-pump function makes it particularly useful for coordinating irrigation pumps with active watering zones.
