Economical operation according to air conditioner use

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 xes the operating frequency, allows smooth inspection, even for
inv

erter models.

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.

. Advantage of New MA Remote Controller

!

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.

●Reduces maintenance work drastically.

●Enables you to check operation data of the indoor and outdoor units by remote controller.
Furthermore, use of maintenance stable-operation control that fixes the operating frequency, allows smooth inspection, even for
inverter models.

1. Maintenance Mode Operating Method

* If you are going to use the " 2. Guide for Operation Condition ", set the airflow to "High" before activating maintenance mode.

●

Switching to maintenance mode

Maintenance mode can be activated either when the air conditioner is operated or stopped.
It cannot be activated during test run.

Maintenance information can be viewed even if the air conditioner is stopped.
