Trolmaster Digital Day/Night Remote Controller （BETA-1）
The Beta-1 is a simple solution for the Mini Split Air Conditioners.
It uses the remote control that came with your mini split air-conditioner to “learn” how to change the setpoints on the mini-split. Just about any brand of mini-split unit can be controlled by the Beta-1. Once the Beta-1 learns the signals from your remote controller, it will automatically change the setpoint on the mini-split to two separate Day and Night temperatures. It does this AUTOMATICALLY by using a small IR (infrared) emitter / sending unit that will send the same signal to the mini-split, as the remote control would normally send.
