The ARS-1 remote station doesn't seem to work properly with my Air Conditioning (AC).

Residential mini-split/window unit AC's can be tricky to get the temperature stabilised in your grow room, and it's particularly tricky to do the 'Teach and Learn' process for Air Conditioners with dual function, Heat & Cool.

Externally, different climates affect your room temperature.
Internally, different sizes/types of a grow room require different quality/quantities of AC.

If you set your Air Conditioner in auto mode, it might get confused about if it should be using heat mode at night or cool mode in the daytime. You can do the teach and learn the process on our ARS-1, teach the lowest temperature on 'cool mode' on your Air Conditioner remote, and highest temperature on 'heat mode'. Then play with the setpoint on the main controller.
