Description
Automated Dehumidifier Control for Hydro-X Systems
The TrolMaster Hydro-X Humidistat Station (HS-1) is a dedicated humidity control station designed to automate commercial dehumidifiers with a 24V low-voltage control terminal. Working seamlessly with the TrolMaster Hydro-X Environmental Control System, the HS-1 functions as an external humidistat, allowing precise humidity management without switching the high current loads associated with commercial dehumidifiers.
The HS-1 displays both the current humidity and target humidity setpoint on its built-in LCD screen, enabling accurate monitoring and simple adjustments. With plug-and-play RJ12 connectivity, address assignment, and Micro SD firmware update capability, it provides an easy and reliable solution for maintaining optimal humidity levels in professional grow rooms.

Why Choose the TrolMaster HS-1?
The TrolMaster HS-1 offers a professional solution for controlling commercial dehumidifiers equipped with 24V control terminals. By acting as a digital external humidistat, it allows the Hydro-X system to automatically maintain precise humidity levels without handling the high electrical loads of the dehumidifier itself. This results in more reliable operation, improved environmental stability, and simplified climate management.
FAQs
What is the HS-1 used for?
The HS-1 is designed to control commercial dehumidifiers that feature a 24V low-voltage control terminal through the TrolMaster Hydro-X Control System.
Does the HS-1 replace the dehumidifier's built-in humidistat?
Yes. The HS-1 functions as an external digital humidistat, providing more precise humidity control through the Hydro-X controller.
Can it control residential plug-in dehumidifiers?
No. The HS-1 is intended for commercial dehumidifiers with 24V low-voltage control inputs. Standard plug-in units typically require a different control solution.
Is installation easy?
Yes. The HS-1 features plug-and-play RJ12 connectivity, simple address assignment, and includes the cables required for installation.
Can the firmware be updated?
Yes. Firmware updates can be installed using a Micro SD card with a capacity of 32GB or less.
