The TrolMaster HS-1 is a dedicated 24V low-voltage humidistat interface that connects commercial dehumidifiers with a 24V humidistat/control terminal directly to the TrolMaster Hydro-X system. Instead of switching the dehumidifier's high-amperage compressor load through an external relay, the HS-1 sends a low-voltage 24V control signal to the dehumidifier's own internal relay. This allows Hydro-X to manage independent Day/Night humidity setpoints while keeping the high-inrush compressor load inside the dehumidifier.

Key Advantage: The HS-1 provides a safe, low-voltage method of integrating commercial dehumidifiers with Hydro-X, avoiding direct switching of the compressor's high-inrush electrical load. It is particularly useful for commercial dehumidifiers such as Quest or Anden units that provide a 24V external humidistat input.
