An air-conditioning controller is configured to receive an operation input for an air-conditioning apparatus capable of being set to a plurality of airflow direction settings. The air-conditioning controller includes a switching button, a determination unit and a display unit. The switching button is for switching between the airflow direction settings. The determination unit is configured to determine a currently selected airflow direction setting based on an operation input inputted via the switching button. The display unit is configured to simultaneously display an image and a character corresponding to the airflow direction setting determined to be currently selected by the determination unit.

Air-conditioning controller

An air conditioning controller includes a storage component, a data receiving component configured to receive set numeric data, a display component configured to display data, and a control component. The storage component has stored operation explanation data, relationship explanation data, and setting layout display data stored therein. The stored operation explanation data defines operations of functions executed in the air conditioner. The relationship explanation data defines relationships between explanations of operations of functions and values that are set. The setting display layout data includes setting display region data and explanation display region data. The control component is configured to cause the set numeric data that the data receiving component has received to be displayed in a setting display region while causing the operation explanation data and the relationship explanation data to be displayed in an explanation display region in accordance with the setting display layout data.

Air conditioning controller

A remote control unit of an air conditioning apparatus includes a display unit, a cursor-moving member, a confirmation member, and a controller. The display unit displays a menu and a cursor that indicates an item among a plurality of items inside the menu and is moved by the cursor-moving member when operated by a user. The confirmation member is configured to decide that the item is to be executed. The controller controls the display unit in response to the cursor-moving member or confirmation member being operated, and stores screen display modes displayed on the display unit. Upon receiving a predetermined input from the confirmation member, the controller causes items allowing selection of the display modes to be displayed on the menu.

Remote control unit of air conditioning apparatus

Driving control device for air conditioner

A transmission device is disclosed wherein a plurality of control units each having a transmitting/receiving block connected to one another through a positive signal line and a negative signal line, and bidirectional signal transmission is carried out with a predetermined polarity among the control units. The signal lines of the transmission device are connected to a power superposing source for applying a predetermined DC voltage to the signal lines and each of the control units include a signal switch connected to the transmitting/receiving block for inverting and switching a transmission signal sent or received by the transmitting/receiving block, and a polarity judging device adapted to supply a homopolar signal when the potential of the positive signal line is higher than the potential of the negative signal line, and adapted to supply a heteropolar signal when the potential of the positive signal line is lower than the potential of the negative signal line. The control unit further includes a changeover control adapted to supply a switching signal to the signal switch such that the signal switch inverts and switches the transmission signal, when the polarity judging device supplies a heteropolar signal.
