SiBE01-503 Introduction 1. Introduction 1.1 Safety Cautions Cautions and Warnings Be sure to read the following safety cautions before conducting repair work. Warning” and “ Caution”. The “ The caution items are classified into “ 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 SiBE01-503 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.
SiBE01-503 Introduction Warning Be sure to use the specified cable to connect between the indoor and outdoor units. Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. Improper connections can cause excessive heat generation or fire. When connecting the cable between the indoor and outdoor units, make sure that the terminal cover does not lift off or dismount because of the cable.
Introduction SiBE01-503 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.

Functions SiBE01-503 1. Functions 1.1 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.
SiBE01-503 1.2 Functions Fan Speed Control for Indoor Units Control Mode The air flow 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 troubleshooting for fan motor on page 61. Phase Steps Phase control and fan speed control contains 7 steps:LL, L, LM, M, HM, H, and HH.
Functions 1.3 SiBE01-503 Thermostat Control Thermostat control is based on the difference between the room temperature and the setpoint.
SiBE01-503 1.4 Functions Automatic Operation Outline When the automatic mode is selected with the remote controller, the microcomputer determines the operation mode from cooling and heating according to the room temperature and the setpoint. The unit automatically switches the operation mode to cooling or heating to maintain the room temperature.
Functions 1.5 SiBE01-503 Programme Dry Function Outline Programme dry function removes humidity while preventing the room temperature from lowering. Since the microcomputer controls both the temperature and air flow rate, the temperature adjustment and fan adjustment buttons are inoperable in this mode. Details of the Control The microcomputer automatically sets the target temperature and fan setting (L tap). Target temperature is determined as follows.
SiBE01-503 1.6 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 lowers the temperature setting slightly in the case of heating, or raises it slightly in the case of cooling, for economical operations.
Functions 1.7 SiBE01-503 POWERFUL Operation Outline In order to exploit the cooling and heating capacity to full extent, operate the air conditioner by increasing the indoor fan rotating speed. Details of the Control When POWERFUL button is pushed, the fan speed and the target temperature will be converted to the following states for 20 minutes. Operation mode Cooling Heating Fan speed HH tap HH tap Target temperature 18°C 30°C Ex.) : POWERFUL operation in cooling mode. Target temp. Set temp.
SiBE01-503 1.8 Functions Other Functions 1.8.1 Hot Start Function In order to prevent the cold draft that normally comes when heating operation starts, the temperature of the indoor heat exchanger is detected, and either the air flow is stopped or is made very weak thereby carrying out comfortable heating of the room. *The cold draft is also prevented using a similar control when the thermostat turns OFF. 1.8.
Function of Thermistor SiBE01-503 2. Function of Thermistor A B Four way valve Compressor (R4733) A Outdoor Heat Exchanger Thermistor (DCB) 1. The outdoor heat exchanger thermistor is used for high pressure control during cooling operation. B Indoor Heat Exchanger Thermistor (DCN) 1. The indoor heat exchanger thermistor is used to prevent freezing. During the cooling operation, if the temperature drops abnormally, the operating frequency becomes lower, then the operation must be halted.
SiBE01-503 Control Specification 3. Control Specification 3.1 Four Way Valve Switching Outline Current is conducted during heating operation, and current is not conducted during cooling or defrosting. In order to eliminate the switching sound (as the four way valve coil switches from ON to OFF) when the heating is stopped, the delay switch of the four way valve is carried out after the operation stopped. Detail The four way valve is switched 2 minutes after the compressor stops. 3.
Control Specification 3.6 Outline Detail SiBE01-503 Heating Peak-cut Control During heating operation, heating peak-cut control is activated according to the temperature of the indoor heat exchanger to prevent abnormal high pressure. Conditions for starting Temperature of the indoor heat exchanger ≥ 63°C (FTYN models), 65°C (ATY models) While controlling The compressor halts. The outdoor fan switches ON/OFF according to the temperature of the indoor heat exchanger.
SiBE01-503 3.8 Control Specification Defrost Control Outline In heating, defrosting is carried out by the cooling cycle (reverse cycle) to prevent the outdoor heat exchanger being frosted. The defrosting time or outdoor heat exchanger temperature must be more than its fixed value when finishing. Detail Time chart for 35 class Heating Defrosting Heating 86sec. Compressor 86sec. ON OFF 73sec. Four way valve Outdoor unit fan Indoor unit fan 73sec.
