1. Weekly Timer

The built-in weekly timer enables you not only to make on/off settings but also temperature settings. Up to 8 patterns can be set for each day of the week.

Saves you money and space because you need only one remote controller.

2. Easy Maintenance Function (Only for PUHZ type)

Enables you to check necessary data on site, drastically reducing the time required for maintenance work.

Information useful for maintenance can be displayed on the remote controller.

Outdoor unit information can be checked even from inside a building.

Furthermore, use of maintenance stable-operation control that fixes the operating frequency, allows smooth inspection, even for inverter models.

<Display information> Outputs data for nine items.

Compressor information	Outdoor unit information	Indoor unit information
• Accumulated operating time	• Heat exchanger temperature	• Heat exchanger temperature
• Number of ON/OFF times	• Discharge temperature	• Room temperature
• Operating current	• Outside air temperature	• Filter operating time

The contact telephone number to be called when an error occurs is displayed automatically.

This helps smooth contact with appropriate personnel when an error occurs.

The contact telephone number of the maintenance company to be called when an error occurs can be registered in advance. When an error occurs, the contact telephone number will automatically appear, allowing you to call without difficult .

Displays the contact number in case of abnormality.

4. The Other Functions

4.1 Temperature Range Limit Setting

Enables operation of air conditioner at comfortable temperatures at all times.

Upper and lower limits can be established for the temperature setting. This prevents overcooling or overheating, thereby contributing to energy saving.

4.2 Auto Off Timer

Shuts off wasteful air conditioner operations.

Operation is stopped automatically when the preset time elapses following the start of operation, thereby preventing wasteful operations.

The time can be set from 30 minutes to 4 hours in 30-minute increments.

4.3 Simple Operation Lock

Prevents others from changing settings without permission.

This lets you disable all the buttons or all the buttons except for the [ON/OFF] button, preventing mischief and incorrect operations.
