How do I operate the air conditioner without the remote control?

Press the MANUAL CONTROL button once to activate FORCED AUTO mode, press it a second time to activate FORCED COOLING mode, and press it a third time to turn the unit off. The manual control button is located on the right-hand side of the indoor unit, accessible by opening the front panel. Note that manual operation is intended for emergency use only and is not a long-term solution. (Page 35)
