SiEBE12-625 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 SiEBE12-625 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.
SiEBE12-625 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 SiEBE12-625 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.

SiEBE12-625 Part 4 Function and Control 1. Main Functions......................................................................................56 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 1.10 1.11 1.12 1.13 Frequency Principle................................................................................56 Power-Airflow Dual Flaps, Wide Angle Louvers and Auto-Swing ..........58 Operation Starting Control......................................................................
Main Functions SiEBE12-625 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.
SiEBE12-625 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 SiEBE12-625 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.
SiEBE12-625 Main Functions FTK(X)S20-50D The vertical swing flap is controlled not to blow the air directly on the person in the room. The airflow rate is controlled automatically within the following steps. Cooling: L tap – MH tap (same as AUTOMATIC) Heating: ML tap – M tap The latest command has the priority between POWERFUL and COMFORT AIRFLOW.
Main Functions 1.3 SiEBE12-625 Operation Starting Control FTXG25-35E, CTXG50E The system carries out the following control at the beginning to conduct every functional parts properly. 1. Opening the front panel fully 2. Output of the ΔD signal after the front panel starts moving 3. Opening the flap fully after the front panel opens fully 4.
SiEBE12-625 1.4 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 204. Phase Steps Phase control and fan speed control contains 9 steps: LLL, LL, SL, L, ML, M, MH, H and HH.
Main Functions 1.5 SiEBE12-625 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.
SiEBE12-625 1.6 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.
Main Functions 1.7 SiEBE12-625 Thermostat Control Thermostat control is based on the difference between the room temperature and the setpoint. Thermostat OFF Condition The temperature difference is in the zone A. Thermostat ON Condition The temperature difference is above the zone C after being in the zone A. The system resumes from defrost control in any zones except A. The operation turns on in any zones except A.
SiEBE12-625 1.8 Main Functions Night Set Mode When the OFF timer is set, the Night Set circuit automatically activates. The Night Set circuit maintains the airflow setting made by users. The Night Set Circuit The Night Set circuit continues heating or cooling the room at the set temperature for the first one hour, then automatically raises the temperature setting slightly in the case of cooling, or lowers it slightly in the case of heating, for economical operations.
Main Functions 1.9 Outline SiEBE12-625 ECONO Mode FTK(X)S20-50D The "ECONO mode" reduces the maximum operating current and power consumption by approx. 30% during start up etc.. This mode is particularly convenient for energy-saving-oriented users. It is also a major bonus for those whose breaker capacities do not allow the use of multiple electrical devices and air conditioners. It is easily activated from the wireless remote controller by pushing the ECONO button.
SiEBE12-625 Main Functions 1.10 INTELLIGENT EYE (Wall Mounted Type Only) This is the function that detects existence of humans in the room by a human motion sensor (INTELLIGENT EYE) and reduces the capacity when there is no human in the room in order to save electricity. Processing 1. Detection method by Intelligent Eye sampling (20msec) Sensor output 1sec If the sensor detects the outputs 10 times/sec. or more, it judges humans exist.

Others 1.1 Test Run from the Remote Controller For Heat pump In cooling mode, select the lowest programmable temperature; in heating mode, select the highest programmable temperature. Trial operation may be disabled in either mode depending on the room temperature. After trial operation is complete, set the temperature to a normal level.
SiEBE12-625 1.2 Others Jumper Settings 1.2.1 When Two Units are Installed in One Room When two indoor units are installed in one room, the two wireless remote controllers can be set for different addresses. How to set the different addresses Control PCB of the indoor unit (1) Remove the electrical box. (2) Cut the address jumper JA on the control PCB. Wireless remote controller (1) Slide the front cover and take it off. (2) Cut the address jumper J4.
Others SiEBE12-625 1.2.3 Adjusting the Angle of the Intelligent Eye Sensor FTK(X)S20-35C Once installation of the indoor unit is complete, adjust the angle of the Intelligent eye sensor to ensure the detection area properly covers the room. (Adjustable angle : 15° to right and left of center) 15° 15° Intelligent-eye sensor Gently push and slide the sensor to adjust the angle. Aim so that the sensor is pointing to the center of the room, or to the part of the room that is most frequently used.
