Bring your mini-split or window AC into an automated grow roomThe TrolMaster ARS-2 Universal IR Air Conditioner Remote Station lets a Hydro-X, Tent-X or Green-X controller take full control of a compatible air conditioner. It learns the infrared commands from the AC's own remote, then automatically switches Cool, Heat and Auto modes as grow room conditions change. Since temperature swings slow vegetative growth, reduce nutrient uptake and stress plants in flower, the ARS-2 gives you automated, stable climate control that supports healthy canopy development and better yields.What's Included 1 x AC Remote Station (ARS-2) 1 x IR signal emitter 1 x RJ12 connection cable Key Benefits Integrates mini-split and window AC units with TrolMaster control systems Cool, Heat and Auto modes supported for full climate management IR learning from the AC's original remote, no extra hardware on the AC side Automated day and night temperature management tied to the lighting cycle Programmable idle periods to cut unnecessary AC run time and energy use Plug-and-play RJ12 connectivity with firmware updates via MicroSD Fixing temperature swings between lights-on and lights-offGrow lights and equipment push heat into the room during the day, then temperatures drop once they switch off. If the AC is not adjusting with that cycle, plants sit through environmental stress that slows growth and blunts nutrient uptake. With commands learned straight from the AC remote, the ARS-2 lets the controller switch cooling, heating or auto mode on its own schedule, holding stable temperatures through both day and night setpoints for stronger roots, better nutrient uptake and improved flowering.How to Use Connect the ARS-2 to your Hydro-X, Tent-X or Green-X controller via the RJ12 cable. Position the IR emitter so it faces the indoor AC unit. Use the ARS-2 to learn the Cool, Heat and Auto commands from the AC's original remote. Set day and night temperature targets in the controller. Add optional idle or off periods to reduce unnecessary AC operation. The controller then sends IR commands automatically to hold grow room conditions steady.
