Please show me the heads, inside and outside of head photos so I can see the components. Also what do the individual controls look like? I have ASUH15LPAS, 09LPAS, and 07LPAS on a quote from an installer but I haven't been able to read anything about them or even see them. I especially want to see the control with buttons, screen and close up view of the symbols plus something that explains the symbols.

The Fujitsu ACUH07LUAS1 consists of both indoor and outdoor units. The indoor unit is a compact cassette-type air conditioner designed for multi-room systems. It includes parts such as a bracket panel, louver spring, step motor, shaft cover, drain pan, air filter, and remote controller. The outdoor unit is designed to accommodate multiple indoor units.

For the ASUH15LPAS, ASUH09LPAS, and ASUH07LPAS models, individual controls and symbols are not explicitly listed in the provided information. However, these models feature a wireless remote controller with an optional wired version. The remote controller is responsible for adjusting temperature, fan speed, and operation modes, but specific button layouts and symbols are not detailed in the given content.
