Device Control Stations

Expand your Trolmaster environmental system with our full range of device control stations, including thermostat replacements, humidistat controls, and dry-contact modules. These modules let your Hydro-X or Aqua-X controller manage HVAC systems, mini-split air conditioners, humidifiers, and dehumidifiers, all from one central automation platform.

How device stations extend your controller

A base environmental controller handles core sensing and scheduling, but device stations are what actually let it control specific equipment types — a thermostat station replaces your HVAC's existing thermostat wiring, a humidistat station takes over dehumidifier control, and so on. Each module is designed for a specific device category, letting you build a fully integrated system piece by piece.

Mini-split AC control

Products like the Trolmaster ARS-1 solve a common problem: most mini-split air conditioners only support one temperature setting via their remote, with no easy way to automate separate day/night targets. These modules "learn" your existing remote's signals, then automatically switch setpoints based on your controller's day/night schedule.

Dry-contact vs direct voltage modules

Some devices need direct voltage switching (like the DST-2 for heating/cooling under 10A), while others use dry-contact relay closure (like the DSD-1) to trigger devices that have their own power supply — check which type matches your specific equipment before ordering.

FAQ

Can these modules work with any brand of HVAC or mini-split unit?
Generally yes, provided your unit came with an IR remote control — the module "learns" the remote's codes regardless of brand, making compatibility broad rather than brand-specific.

Do I need a different module for every device type?
Yes — each device station is designed for a specific control method (thermostat replacement, dry-contact, direct voltage), so you'll typically need one module per connected device type.

What happens if my controller loses power?
This varies by system — check your specific controller's behaviour, though most maintain basic settings through short power interruptions.
