AC Remote Station, Universal Remote Control for any remote controlled AC such as Mini-Split AC system

What the ARS-1 Does

Mini-split AC units are the backbone of climate control in most commercial grow rooms — but their stock remotes only accept manual input. The ARS-1 solves that by acting as a universal IR-learning bridge between the Hydro-X control system and any infrared-remote-controlled AC unit. The station captures the IR codes from your existing AC remote through a simple teach procedure, then replays those exact signals automatically based on the programmed schedule.

Once the ARS-1 has learned your AC's IR codes, you set day and night temperature targets inside the Hydro-X interface. The ARS-1 then fires the appropriate IR command to the indoor head unit whenever the Hydro-X photocell transitions between day and night states — no manual intervention required. The result is consistent, repeatable temperature transitions every light cycle without any physical access to the remote or the unit.

Compatibility and System Requirements

The ARS-1 is designed to work with most mini-split AC systems and select window AC units — the single compatibility requirement is that the AC unit shipped with an IR (infrared) handheld remote. The station is brand-agnostic across a wide range of manufacturers. Note: TrolMaster documents that the ARS-1 is currently not compatible with certain specific brands including Daikin, Mr. Cool, Innovair, Denali Aire, Cooper and Hunter — confirm your unit's brand before ordering.

System integration requires a TrolMaster Hydro-X controller (HCS-1 or compatible). The ARS-1 connects via RJ12 cable and receives an address assignment from the Hydro-X at first boot. Up to 24 temperature setpoints for both unary and binary remote control types can be learned. Firmware updates are handled via Micro-SD card (32 GB or smaller). All cables and the IR emitter are included in the box.

Key Features for Commercial Operations

For multi-room or multi-zone commercial facilities, the ability to automate AC setpoint changes across multiple head units through a single Hydro-X network significantly reduces labor and eliminates operator error during light-cycle transitions. Rather than relying on staff to manually re-set AC remotes at lights-on and lights-off, the ARS-1 handles every transition on the programmed schedule.

The unit includes an LCD display for on-device status and setup confirmation, address assignment for multi-station deployments, and a plug-and-play RJ12 connection to the Hydro-X bus. The accessory IR emitter mounts near the indoor AC head for reliable signal delivery. Working environment rating of 32–122 °F and ≤90% RH makes it suitable for the humidity-variable conditions typical of active grow rooms.

How It Fits a Commercial Build

The ARS-1 is the right solution when a facility is running mini-split AC for cooling and wants centralized, automated climate control without replacing the AC hardware. Instead of investing in a full dedicated environmental controller with proprietary AC integration, operators can retrofit their existing mini-splits into the Hydro-X ecosystem at a fraction of the cost — preserving the AC equipment investment while gaining the scheduling and automation capabilities of the Hydro-X platform.

In a multi-room build, one ARS-1 per AC head unit allows the Hydro-X to manage temperature transitions room by room. Combined with TrolMaster's humidity, CO2, and lighting stations on the same RJ12 bus, the ARS-1 becomes one node in a fully integrated environmental control network — the standard approach for operators who need documented, repeatable climate conditions across every canopy zone.
