Hold buttons down for 5 seconds to switch from Fahrenheit to Centigrade. NOTE: In AUTO operation, the system selects a temperature setting and appropriate COOL or HEAT mode based on beginning room Remote Controller In the ARC433A series, the temperature display sections on the main unit indicate corresponding codes. 1. When the timer cancel button is held down for 5 seconds, a “00” indication flashes on the temperature display section. 2.
