[. . . ] · Ensure the difference between the intake temperature and the discharge is more than 8°C. 29 CS-E9EKEB CU-E9EKEB / CS-E12EKEB CU-E12EKEB 12 Operation And Control 12. 1. Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature. 12. 1. 1. Internal Setting Temperature Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit. 12. 1. 2. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes). Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control). 12. 1. 2. 1.

Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vane will shift to close position. Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close position. 30 CS-E9EKEB CU-E9EKEB / CS-E12EKEB CU-E12EKEB 12. 1. 2. 2. Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below.

Quiet operation start condition · When "quiet" button at remote control is pressed. When one of the following conditions is satisfied, quiet operation stops: a. When quiet operation is stopped, operation is shifted to normal operation with previous setting. [. . . ] · There are many high voltage components within the heat sink cover so never touch the interior during operation.
