In the remote controller function selection mode, the settings for four types of functions can be made or changed as necessary.
4) Narrowed preset temperature range mode
The default temperature ranges are 19 C to 30 C in the cooling/dry mode and 17 C to 28 C in the heating mode and 19 C to 28 C in the auto mode.
By changing these ranges (raising the lower limit for the cooling/dry mode and lowering the upper limit for the heating mode), energy can be saved.
When making the temperature range setting on the simultaneous cooling/heating type units that supports the automatic operation mode to save on
energy consumption, enable the Skip-Auto-Mode setting to make the automatic operation mode unselectable. If the automatic operation mode is
selected, the energy-saving function may not work properly.
When connected to the air conditioning units that do not support the automatic operation mode, the setting for the Skip-Auto-Mode, restricted preset
temperature range mode (AUTO), and operation mode display selection mode are invalid. If an attempt is made to change the preset temperature range,
“LIMIT TEMP.” appears on the display.
