Features:

• The ARS-1 is a universal controller that works with most mini-split air conditioners (& some window-type AC units too), as long as the unit came with an IR / infrared remote controller.
• Use the remote control that came with the unit to “teach” the IR signals to the ARS-1 module.
• Once the ARS-1 “learns” the remote control codes, the ARS-1 will send those same signals to the indoor mini-split head unit changing the set point to the desired Day or Night temperature setting automatically base on the photocell sensor status.
