•During heating operation, operate the followings control.

1.During Remote Control setting is 18°C & above

Indoor Fan Speed	Min Hz
More than Hi	27

More than Lo	27
Under Lo	27

However, when less than thermo OFF for 100 sec. continuously, the above control will be cancel.

8.2.1.11. DC Current Protection Control

Purpose

In order to control DC current rise in a compressor low frequency region, load is detected with from indoor/outdoor heat exchanger temperature, Hz control is performed.

Control contents

1. During cooling and dry except test mode

2.During heating compressor operation, except test mode. (However, official approval mode removes)

8.2.2.Protection Control For Cooling & Soft Dry Operation8.2.2.1.Outdoor Air Temperature Control

The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the diagram below. This control will begin one minute after the compressor starts.
