SiENBE12-522A Introduction 1. Introduction 1.1 Safety Cautions Cautions and Warnings " Be sure to read the following safety cautions before conducting repair work. " The caution items are classified into “ Warning” and “ Caution”. The “ Warning” items are especially important since they can lead to death or serious injury if they are not followed closely. The “ Caution” items can also lead to serious accidents under some conditions if they are not followed.
Introduction SiENBE12-522A Caution Do not repair the electrical components with wet hands. Working on the equipment with wet hands can cause an electrical shock. Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical shock. Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid electrical shocks. Be sure to turn off the power switch and unplug the power cable when cleaning the equipment.
SiENBE12-522A Introduction Warning Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to the electrical equipment, the internal wiring regulations and the instruction manual for installation when conducting electrical work. Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire. Be sure to use the specified cable to connect between the indoor and outdoor units.
Introduction SiENBE12-522A Warning Do not use a joined power cable or extension cable, or share the same power outlet with other electrical appliances, since it can cause an electrical shock, excessive heat generation or fire. Caution Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, fire or an electrical shock.

Main Functions SiENBE12-522A 1. Main Functions Note: 1.1 See the list of functions for the functions applicable to different models. Frequency Principle Main Control Parameters The compressor is frequency-controlled during normal operation.
SiENBE12-522A Inverter Features Main Functions The inverter provides the following features: " The regulating capacity can be changed according to the changes in the outdoor air temperature and cooling / heating load. " Quick heating and quick cooling The compressor rotational speed is increased when starting the heating (or cooling). This enables a quick set temperature.
Main Functions 1.2 SiENBE12-522A Power-Airflow Dual Flaps, Wide Angle Louvers and Auto-Swing Power-airflow Dual Flaps The large flaps send a large volume of air downwards to the floor. The flap provides an optimum control area in cooling, heating and dry mode. Heating Mode During heating mode, the large flap enables direct warm air straight downwards. The flap presses the warm air above the floor to reach the entire room. Cooling Mode During cooling mode, the flap retracts into the indoor unit.
SiENBE12-522A 1.3 Main Functions Fan Speed Control for Indoor Units Control Mode The airflow rate can be automatically controlled depending on the difference between the set temperature and the room temperature. This is done through phase control and Hall IC control. For more information about Hall IC, refer to the troubleshooting for fan motor on page 210. Phase Steps Phase control and fan speed control contains 9 steps: LLL, LL, SL, L, ML, M, MH, H and HH.
Main Functions 1.4 SiENBE12-522A Programme Dry Function Programme dry function removes humidity while preventing the room temperature from lowering. Since the microcomputer controls both the temperature and air flow volume, the temperature adjustment and fan adjustment buttons are inoperable in this mode. In Case of Inverter Units The microcomputer automatically sets the temperature and fan settings.
SiENBE12-522A 1.5 Main Functions Automatic Operation Automatic Cooling / Heating Function (Heat Pump Only) When the AUTO mode is selected with the remote controller, the microcomputer automatically determines the operation mode from cooling and heating according to the room temperature and setting temperature at the time of the operation startup, and automatically operates in that mode.
