7 Remote controller functions selection

In the remote controller function selection mode, three functions can be selected and changed. Select and change these functions, as required. For the operating instructions refer to “(6) How to select the remote controller functions” of 3 How to Operate in Instruction Book.

(A) Operation mode display selection mode (“AUTO” mode heating/cooling display selection)

When the AUTO mode was selected with the remote controller, the indoor unit is judged from the room temperature and heating or cooling is performed automatically. In this case, “AUTO” “COOLING” or “AUTO” “HEATING” is displayed at the remote controller. However, only “AUTO” without “COOLING” or “HEATING” can also be displayed.

(B) Room temperature display selection mode (Room temperature display/no display selection)

Normally, the intake air temperature is displayed at the remote controller. However, no display can also be selected.

(C)Set temperature range limit mode

Normally, the set temperature adjustment range of the standard air conditioner can be freely set to a temperature within the respective temperature adjustment range, 19°C to 30°C for cooling and dry, 17°C to 28°C for heating and 19°C to 28°C for AUTO mode. However, further limitation can be applied to the lower limit temperature and the upper limit temperature of these temperature adjustment ranges. For example, if a higher than normal lower limit temperature is set for cooling and dry (19°C ➝ 25°C) and a lower upper limit temperature is set for heating (28°C ➝ 20°C), substantial energy savings can be realized by preventing excessive cooling or heating.

- If using an air conditioner with AUTO mode that simultaneously runs cooling and heating operations, before you can use the set temperature adjustment range limit mode and enjoy the benefits of saving energy, you must first choose to skip automatic

CAUTION

mode using the skip automatic mode setting. This energy saving function may not work if AUTO mode was used.

- If the controller is connected to an air conditioner without AUTO mode, skip AUTO mode setting mode, set temperature range limit mode (AUTO), operation mode display selection mode will be unavailable.
