The TrolMaster Beta-1 is a standalone digital day/night temperature controller for IR-controlled mini-split air conditioners. It learns the infrared commands from the AC's original remote, then automatically switches between independent lights-on and lights-off temperature setpoints. A built-in photocell detects the room's light cycle, while the included wired IR emitter sends the appropriate commands to the mini-split without requiring any modification or rewiring of the AC.

Key Advantage: The Beta-1 provides automated day/night temperature control for existing IR-controlled mini-splits without rewiring the AC. Its combination of IR learning, photocell-based day/night switching, remote temperature sensing, and automatic command retransmission makes it a simple retrofit solution for rooms that need dedicated AC automation without installing a full environmental-control system.
