The TrolMaster DSH-1 is a plug-and-play humidity control relay designed to integrate standard humidifiers and dehumidifiers directly into the TrolMaster Hydro-X environmental control system. It gives Hydro-X direct ON/OFF control based on live RH sensor readings, programmed setpoints, and schedules. The module supports 100–240 VAC equipment up to 10A, with TrolMaster recommending dehumidifier loads below 7A.
