The TrolMaster HS-1 Humidistat Station is a specialized device designed for controlling dehumidifiers with a 24V terminal. It integrates seamlessly with the Hydro-X control system, allowing users to manage humidity levels in their environment effectively. The station's primary function is to monitor and regulate relative humidity, ensuring that the environment maintains a desired setpoint.

Function Description

The HS-1 Humidistat Station operates by connecting to a Hydro-X system via four data lines through its back panel ports. This connection enables the HS-1 to control any 24V dehumidifier. Users can set their preferred humidity levels for both Day and Night modes within the Hydro-X system's Humidity Settings. Once configured, the HS-1 unit takes over, activating the dehumidifier when the measured humidity exceeds the setpoint, thereby working to reduce it to the desired level.

The device features a clear LCD screen that displays both the setpoint humidity (in the upper part of the screen) and the current measured humidity (in the lower part). This immediate visual feedback allows users to quickly assess the current environmental conditions and the device's operational status. When the current humidity is higher than the setpoint, the HS-1 unit will engage the connected dehumidifier to bring the humidity down.

Usage Features

The HS-1 Humidistat Station offers several features designed for ease of use and effective humidity management:

Digital Control of Relative Humidity: The device provides precise digital control over relative humidity, allowing for accurate setpoint adjustments.
LCD Display, Easy Operation: The integrated LCD screen simplifies operation by clearly displaying essential information and facilitating straightforward navigation through settings.
Micro-SD for Firmware Update: A Micro-SD card slot is included for convenient firmware updates, ensuring the device can always run the latest software and benefit from improvements or new functionalities.
Seamless Connectivity with Hydro-X: The HS-1 is built for seamless integration with the Hydro-X system, leveraging its advanced control capabilities.
Control Dehumidifier based on Humidity Setpoint: Its core function is to intelligently control a dehumidifier based on user-defined humidity setpoints, maintaining optimal environmental conditions.

Installation and Connection:

Installation involves releasing a bracket from the unit by pulling two tabs outward. This bracket is then mounted to a wall or surface near the dehumidifier. Signal cables from the dehumidifier need to be prepared by peeling off their outer sheath to expose the copper wire. These bare wires are then inserted into the corresponding terminals on the back panel of the HS-1 while pressing the terminal designation button. Releasing the button clamps the wire securely. After verifying the wires are firmly secured, the unit is placed back onto the bracket, and the tabs are pressed back in to lock it in place.

For connection to the Hydro-X system, once the signal wires are successfully connected to the HS-1 unit, an RJ12 cable is used to link the HS-1 to the DEVICES socket on the bottom of the Hydro-X. This establishes communication, allowing the Hydro-X to monitor and manage the HS-1's performance.

Address Assignment:

Upon power-on, if correctly connected, the HS-1's LCD screen will prompt the user to "Please press Addressing Key." If incorrectly connected, it will display "Offline." Pressing the Addressing button on the HS-1 unit allows the Hydro-X to assign an address, such as H1, to the HS-1. The Hydro-X's LCD screen will then confirm "Station H1 has been added." It's important to note that the address (e.g., H1) is not a fixed product code and can vary (e.g., H2) depending on the connection sequence of multiple dehumidifier devices.

FAN Setting:

The HS-1 includes a FAN button that allows users to select either ON or AUTO mode for the fan within an air-conditioner.

AUTO mode: In this mode, the fan runs only when the heating or cooling system is active. This is generally the most common and energy-efficient setting.
ON mode: In this mode, the fan operates continuously, regardless of whether the heating or cooling system is engaged. The available options for fan operation may vary depending on the specific heating/cooling equipment connected.

Firmware Upgrade:

Firmware upgrades are facilitated through a straightforward process. To initiate an upgrade, users need to press and hold the "Addressing" button while re-plugging the RJ12 cable. The upgrade process will then proceed automatically. It is crucial to ensure that the firmware upgrade file is correctly named "hs1_update.hex" for the process to be successful.

Maintenance Features

The HS-1 Humidistat Station is designed with minimal user-serviceable parts, emphasizing safety and durability.

Cleaning: If the surface of the Humidistat Station becomes dirty, it should be wiped with a dry towel.
Environmental Considerations: The control board is intended for indoor use only and should be operated under natural ventilation conditions. It is critical not to expose the Humidistat Station to water or excessive heat.
Grounding: For safety, connecting the ground wire is necessary. In the event of a short circuit, the current will flow through the ground wire, preventing a blown fuse or tripped circuit breaker.
Positioning: The Humidistat Station should be placed in an easily accessible location, allowing for quick removal in case of a fault.
Warranty: The manufacturer provides a three-year warranty from the original date of purchase. During this period, defects will result in replacement or repair using new or reconditioned products or parts. Opening the controller or attempting to repair or disassemble it will void the warranty, as there are no user-serviceable parts inside. Non-professionals are explicitly advised not to open the cabinet to prevent electric shock or damage. For warranty service, the unit should be returned in good packaging along with the original sales receipt to the agent.
