FDC-HKXR 20.1 GENERAL INFORMATION 20.1.1 Specific features (1) Fuzzy control (a) Response speed and stability are enhanced. • The system automatically controls changes of return air temperature, set temperature and room temperature according to the fuzzy control. • The system response speed, can keep room temperature constant, and can adjust room temperature to set temperature quickly. Inverter Hz Set temp. Temp. difference Gradient of temp. operation FUZZY operation Temp. (Return air thermistor) E.E.
FDC-HKXR (3) Installation of automatic address setting function • The address setting method are divided into three types according to wiring method: “Automatic Address Setting,” “Remote control Address Setting.” and “Manual Address Setting.” In case of the Automatic Address Setting, no address needs be set as usual. (4) Connectable indoor capacity Capacity from 50% to 130% is possible.

FDC-HKXR 20.4 OUTLINE OF OPERATION CONTROL BY MICROCOMPUTER (1) Remote controller (Optional parts) FDR,FDUM,FDFL and FDFU series are not provided with AUTO SWING switch. Panel shown below will appear if you open the cover. All contents of display on the LCD are indicated simultaneously for the purpose of explanation. Pull the knob on the cover to this side to open it downward. Filter sign Operation mode display When this sign is indicated, clean the filter.
FDC-HKXR (2) Automatic Operation Once the [Auto] mode is selected by remote control, the operating mode is automatically selected according to the setting temperature and the intake air temperature of the indoor unit and cooling or heating operation is performed. The determination is performed when the thermostat has been in the OFF mode for 10 minutes or more continuously.
FDC-HKXR (5) Dehumidifying (Thermal dry) D C Low -2 B A +2 ▲ High Room temperature setting point • Indoor unit fan will be operated in D block as shown below. 20 sec. Lo OFF 4 min.
FDC-HKXR (7) Value shift adjustment of room air temperature detection in heating Under the standard specifications, the room temperature is adjusted at the setting temperature by controlling the indoor unit capacity based on the setting temperature of thermostat and the suction air temperature. However, where the unit is installed in the ceiling and warm air tends to stay around the ceiling, temperature in the living space may not be adjusted at the setting temperature.
FDC-HKXR (10) Condensate pump motor (DM) control (Only FDT, FDTW, FDTS, FDR, FDUM models) (a) Drain motor is started no sooner than the compressor is turned ON during cooling or dehumidifying operation. The drain motor continues to operate for 2 minutes after the stop of unit operation, stop with the error stop, thermostat stop and at switching from cooling or dehumidifying operation to blowing or heating operation.
FDC-HKXR (11) Defrosting (a) Conditions for starting defrosting When all the following conditions are met, the defrosting operation will start: -2°C Outdoor unit heat exchanger temp. (ThO-R) 1) The cumulative operating time of the compressor comes up to 45 minutes after completion of a defrosting operation, or it comes up to 30 minutes after a heating operation starts (the remote controller is turned on). 2) Five minutes has passed after the compressor was turned off and on.
FDC-HKXR (12) Multiple Units Control-Simultaneous Control of 16 unit with one remote controller (a) Function Multiple units (even of outdoor different systems, 16 units maximum) can be simultaneously controlled by using a remote control switch (a special order item). The remote control switch is used to set the “operation mode”, and all the unit can be operated and stopped at intervals of 0.5 to 1 second in the order of unit number. Thermostat and protective functions of each unit functions independently.
FDC-HKXR (ii) When SW5-1 on the PCB of indoor unit is turned on at the field. Input signal to CnT becomes valid at OFF → ON only and the motion of air conditioner [ON/OFF] is inverted.
FDC-HKXR LP,HP-B controls Under these controls, the high and low level pressures are controlled with the solenoid valves, outdoor fan and other so as to operate the outdoor unit in the optimum condition in accordance with changing load on the indoor unit. Operation patterns consist of the following 12 types and respective functional parts are controlled per each pattern.
FDC-HKXR (17) Compressor operating frequency increase control (a) In the case that at least one in-door unit requires the maximum frequency supply during cooling or heating operation for 6 minutes continuously, the compressor operating frequency is increased by 10 Hz. After that, the maximum frequency is increased by 10 Hz every continuous 6 minutes; however, the upper limit is 30 Hz. (b) When requirement of the maximum frequency ceases, the control is released.
FDC-HKXR (19) Devices related to unit protection and maintenance (a) Test Run Mode The test run mode can be set from the outside by using the switch SW3-4,5 on the outdoor unit control circuit board (i) Switch function Switch SW3-4 SW3-5 Function ON • To operate all connected indoor units. • Indoor units demands the maximum frequency and outdoor units are operated with the maximum frequency according to request from the indoor unit.
FDC-HKXR (iii) Three minutes delay timer The compressor (inverter) will remain in stop state for 3 minutes, when the compressor is stopped by thermostat, ON/OFF swich, and /or by occurrence of trouble. When the power source is turned ON, the 3-minutes delay timer is cancelled.
FDC-HKXR (k) Protection of Power Transistor from Overheat When the temperature of the power transistor increases to the set temperature, stop the inverter immediately and let is reset by itself 3 minutes later. If the power transistor is overheated again within 2 hours, turn off 52C, bring it to an abnormal stop and the inspection displays (Remote controller : E41, indoor unit green LED : Continuous flashing, red LED : OFF, outdoor unit green LED : Continuous flashing, red LED : 4 times flash) will appear.

Contents of communication Connector CnI 14 1 Common 2 12V power supply 3 Transmission from outdoor unit 4 Reception from outdoor unit 5 Watch dog (communication from inverter PCB to outdoor unit PCB) 6 Inverter overheat 7 Current cut 12V Green LED Swings at 4.
FDC-HKXR 2) Louver motor does not operate Inspect at the indoor unit side. Does the louver operate at power on? Operate more than 1 min.
FDC-HKXR 4) Heating operation does not start NO Is heat outputted? Defective indoor unit PCB → Replace. YES (1) Are solenoid valve control relays OK? NO Defective relay → Replace. YES Is AC 200V applied at shunt controller connector CnB? YES Defective SVH (high pressure gas side solenoid valve) → Replace. 1086 NO Defective relay (XH) → Replace. Note (1) This is applicable only when a concentrated shunt controller is used.
FDC-HKXR (3) When the remote controller indication is nomal but the compressor cannot operate: (No check indication) • Give instructions so that the requested best frequency may be output, irrespective of the thermostat condition, from outdoor to indoor. A ccordingly, if the indoor/outdoor transmission is faulty, the compressor cannot operate. • When the SW3-4 is turned on, error indication is not provided if the indoor unit is not connected.
FDC-HKXR (4) Proceduer for checking the outdoor unit irrespective of indoor/outdoor transmission Turn off the outdoor unit power supply (Or pull out the connector CnA2 on the outdoor unit PCB) Set 45 in outdoor unit No. Turn ON the outdoor unit PCB(SW3-7) Turn ON the outdoor unit power supply Open the 63H1 Is the 52C turnd ON? (When connecting the CnA2 on the outdoor unit PCB) (Pull out Faston No.17 on the PCB) NO Does a voltage Appear at the 52C coil.
