The TrolMaster DSC-1 is a plug-and-play CO₂ relay module designed for the Hydro-X environmental control platform. It provides automated, setpoint-driven switching of CO₂ supplementation or exhaust equipment, including CO₂ generators, tank solenoids, and CO₂-triggered exhaust controls. When paired with a compatible CO₂ sensor such as the MBS-S8, the Hydro-X controller uses live PPM readings to activate or deactivate the connected device according to the programmed CO₂ setpoint.

Key Advantage: The DSC-1 connects CO₂ equipment directly to the TrolMaster control bus, allowing the controller to switch the equipment based on actual CO₂ PPM readings rather than a simple timer. Because it is a single-relay module, separate DSC-1 units are required when independently controlling both CO₂ injection and CO₂ exhaust equipment.
