The TrolMaster DST-1 is a single-channel temperature control relay station designed for the Hydro-X environmental control system. It provides automated ON/OFF control of 120V heating and cooling equipment based on programmed temperature setpoints and sensor data. The station connects to the Hydro-X RJ12 bus and is independently addressable, making it suitable for controlling separate temperature devices or zones within a larger installation.
