The TrolMaster DSH-2 is a dedicated 240V humidity control relay designed to integrate commercial humidifiers and dehumidifiers directly with the TrolMaster Hydro-X environmental control system. It provides sensor-driven on/off automation through the Hydro-X RJ12 device bus, allowing connected humidity equipment to follow programmed humidity setpoints and day/night control logic without additional control hardware.
