Example: FDUR 30 8 H EN-SB

9.1 GENERAL INFORMATION9.1.1 Specific features(1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been

reduced by more than 50%.

(2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit.

There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic

noise thus the incidence of microcomputer malfunction has been reduced. The compressor in the outdoor unit has its own self

protection function, that reacts according to abnormal high pressure and excessive high temperature.

(3) There are only five power lines between the outdoor and indoor unit, As no signal wire is used there is no need to separate the

power line from the signal line. One cabtyre cable with 6 wires encased in one sheath is enough for conducting the wiring work

between the outdoor unit and the indoor unit. This contributes to simpler wiring work in the field.

(4) All models have service valves protruding from the outdoor unit for faster flare connection work in the field.

(5) The position of the suction port can be changed.

The suction from the lower inlet is available by replacing the duct connecting section (at the side face) and the lower plate. (They

are changed on site.)

(3) Correction of cooling and heating capacity in relation to one way length of refrigerant piping

It is necessary to correct the cooling and heating capacity in relation to the one way equivalent piping length between the indoor

and outdoor units.

Note (1) Equivalent piping length can be obtained by calculating as follows.

208, 258, 308 series [φ15.88(5/8″)]: Equivalent piping length = Real piping length + (0.10 × Number or bends in piping)

408, 508, series [φ19.05(3/4″)]: Equivalent piping length = Real piping length + (0.15 × Number of bends in piping)

[Equivalent piping length < Limitation length of piping + 5m]

(4) When the outdoor unit is located at a lower height than the indoor unit in cooling operation and when the outdoor unit is located

at a higher height than the indoor unit in heating operation, the following values should be subtracted from the values in the

above table.

Note (1) Values in the table indicate the one way piping length between the indoor and outdoor units.

How to obtain the cooling and heating capacity

Example : The net cooling capacity of the model FDUR308HEN-SB with the air flow “High”, the piping length of 15m, the outdoor unit

located 5m lower than the indoor unit, indoor wet-bulb temperature at 19.0 ˚C and outdoor dry-bulb temperature 35 ˚C is

Net cooling capacity = 7100 × 1.00 × (0.985 - 0.01) × 1.0 = 6923 w

(a) Operation control function by the indoor controller

2) Automatic operation (Only heat pump type)

If the Auto mode is selected on the remote control device, the selection of cooling or heating can be made automatically

depending on the room temperature (and the temperature of indoor heat exchanger). (When the switching between the

cooling and the heating is made within 3 minutes, the compressor will not operate for 3 minutes.) This will make much

easier the switching of cooling/heating at the change of season and can be adapted to the unmanned operation at bank

cash dispenser.

Notes (1) During the automatic switching of cooling/heating theroom temperature is controlled based on the settingof room temperature.

(2) If the temperature of indoor heat exchanger rises be-yond 63˚C during the heating operation, it is switchedautomatically to the cooling operation. For an hourafter this switching, the heating operation is suspendedregardless of the temperature as shown at left.

Notes (1) Operation block A B : Normal cooling operation for 16 minutes after operation is started.

Operation stops by thermostat when the set temperature is reached.

After 16 minutes, normal thermal drying operation starts.

Operation block C D : Operation as above is performed for 8 minutes.

After 8 minutes, normal thermal drying operation starts.

(2) In normal operation, the temperature is checked at 8 minute intervals after normal thermal drying

operation is started, to determine which operation block is to the selected.

Operation block A thermal drying is carried out if the thermostat set temperature is constant.

4) Dehumidifying operation (“THERMAL DRY”)

The compressor, the indoor fan motor and the outdoor fan motor

are operated intermittently under thermistor (ThI-A) control ac-

cording to the appropriate operation block, to provide cooling op-

eration for the dehumidifying.

In the hot spurt mode, the control is conducted at the level +2 higher than the setting temperature at the start of heating operation.

The hot spurt is canceled either after the initial thermostat OFF, when the indoor heat exchanger temperature reaches 61˚C or 60

minutes after the start of the mode.

6) FM control with the heating thermostat turned off (For cold draft prevention) (Only heat pump type)

In order to prevent a cold draft while the heating thermostat is turned off, the indoor blower is controlled in response to the

temperature of the indoor heat exchanger as illustrated below. It should be noted that if SW3-4 on the indoor PCB is turned off, the

indoor blower will stop so far as the temperature of the indoor heat exchanger is lower than 40˚C. It will be turned to the Lo

operation 5 minutes later.

7) Hot start (Cold draft prevention during heating) (Only heat pump type)

1) If the indoor heat exchanger temperature is lower than 30˚C when the heating operation has started, the following indoor

blower control is performed.

(1) In case of the thermostat off condition: Lo operation

(2) In case of the thermostat on condition : Stop

(3) If the indoor heat exchanger temperature exceeds 30˚C or 7 minutes after the beginning of hot start, the hot start

terminates and it returns to the setting airflow of the blower.

2) If the indoor heat exchanger temperature is lower than 30˚C when the unit is heating under the thermo-ON condition, the

indoor fan operates in the Lo mode. As the temperature rises higher than 30 ˚C or 7 minutes after the beginning of hot start,

the hot start terminates and it returns to the setting air flow.

8) Indoor fan control during defrost operation (Only heat pump type)

1) The indoor fan operation is changed from the setting airflow to the Lo operation 40 seconds before the start of defrost

operation (when the defrost thermostat is turned ON) and stops if the indoor heat exchanger temperature drops below 20˚C.

2) After the stop as described in 1)-above, the control will be conducted as illustrated below depending on the indoor heat

exchanger temperature.

3) If the indoor heat exchanger temperature rises beyond 30˚C of 7 minutes after the end of defrosting, the indoor fan control

related to the defrosting is completed.

Note (1) After the thermostat is reset, it returns to the hot startcontrol.
