The Min operation time of COMP under different operating conditions is

Operation Mode Min operation time of COMP

Heat, Cool or Auto Modes 3 min.Fan, Dry, Overflow, Protection modes, or mode change ignored

12.4.2 IFAN operation

• Min time interval between IFAN speed change in AUTOFAN Mode, is 30 sec. • Min time interval between IFAN speed change in H/M/L Mode is 1 sec. • IFAN speed in Heat/Cool Autofan Mode is determined according to the following table:

∆T IFAN Speed∆T ≥ 2 HIGH

2 ≥ ∆T ≥ 1 MED1 ≥ ∆T LOW

where in Heat Mode: ∆T = SPT-RT in Cool Mode: ∆T = RT-SPT

Note:• In Heat Mode, the rules in section 4.0.3 have the higher priority.• The table above can be represent by a hysteresis curve which

will minimize the switching of the IFAN relay and will minimize the change in IFAN speed:

12.4.3 OFAN operation• Min time interval between OFAN ON/OFF state change is 30 sec.

• In general, OFAN starts together with COMP.12.4.4 HE operation

• Minimum Heaters ON or OFF time is 30 sec.

• Heaters can be activated only if IFAN is on.

12.4.5 Protections• High pressure protection is applicable to all operating modes.

• Deicing control is valid in Heat and Auto Heat Mode only.

• Defrosting control is valid in Dry, Cool, Heat and Auto Modes.

• No reset after protection modes.

12.4.6 Thermistors operation

• Return air Temp. is detected by RAT (RT1) in normal Mode, or by RCT (R/C sensor) in I-FEEL Mode.

• Indoor Coil Temp. is detected by ICT (RT2).12.4.6.1 Definition of thermistor faults:

a. Thermistor is disconnected - The thermistor reading is below -30oc.

b. Thermistor is shorted - The thermistor reading is over 75oc.

c. Thermistor Temp reading doesn’t change (irrelevant for RT1) -(i) This test is performed only once after a unit is switched from

OFF/STBY to operation. At the first occurrence of 10 min continuous COMP operation, the current ICT & OCT are compared with those when the COMP was switched from OFF to ON 10 min before. If the ∆T is less than 3oc, the thermistor is regarded as defective.

(ii) The ICT and OCT no-change error can be disabled together by connecting a4.7 kohm resistor (5%) to the OCT connector. These resistors are equivalent to a thermistor at 43+/-1oc and 48+/-1oc respectively.

(iii) Connecting a 4.7k resistor to the ICT connector will disable the ICT no-change error only.

12-6

CONTROL SYSTEM


12.4.6.2 Handling the thermistor faults in a COMP unit

i. ICT/OCT thermistor is disconnected or shorted -The invalid thermistor temperature is replaced by 43oc, so that the unit can continue the normal operation. All protections related to that faulty thermistor will be disabled. For example, in case of any ICT fault, the ICT high pressure protection in Heat Mode and ICT defrost protection in Cool Mode will not operate anymore. The same is also applied to the OCT fault.

ii. RAT thermistor is disconnected or shorted –The RAT will be derived from the ICT by using the equations : Heat Mode: RAT=ICT/2.3

Cool Mode RAT=ICT*4Notes:

• In case of any thermistor failure, the STBY LED will be blinking until the fault condition is corrected.

• User can use the system diagnostics function to find out the nature of the thermistor faults.

i. RAT thermistor is disconnected or shorted –System will operate continuously in the last IFAN & WVL status when turned ON.

Notes:• As in the COMP unit, the STBY LED will be blinking to indicate a

thermistor fault. And, the user can use the system diagnostics function to find out the nature of the fault.

12.5 Cooling Mode - General

1) Room Temperature, RT, is detected by• RAT in normal operation, or• RCT (R/C sensor) in I-FEEL mode.

2) The resolution of RT is 1oc.• RT is activating COMP/WVL if (RT > SPT), and• RT is stopping COMP/WVL if (RT =< SPT).

3) Indoor Coil Temp is detected by ICT (RT2).

4) Outdoor Coil Temp is detected by OCT (RT3).

5) OFAN OPERATIONS• OFAN starts together with COMP in general.

Notes :• No compensation will be activated in Forced operation modes

12.6.2 IF operating rules• As a general rule for RC and SH groups, when COMP is ON, excluding

protection modes, IFAN will be switched ON if • ICT > 35oc or

at the IFTC 30 sec after the COMP is switched ON. In this case, the IFAN will be started at low speed.

Notes :1) In SH or RC group, if HE is set to OFF due to low ICT, IFAN will be

switched to LOW and will be turned OFF after 30 sec.2) An exception to this rule (4.0.3.a) is the Back-up mode for SH. • In RC and SH groups, whenever COMP & HE are both

OFF, excluding protection modes, IFAN operation will be according to the following:

In other models IFAN will operate in low speed for 30 sec and then stop. If COMP is OFF for more than 3 minutes and IFEEL Mode is inactive, IFAN will operate in low speed according to the following graph:

• Switching-temperature between Cooling and Heating is SPT ± 3oc.

• Autofan in Automatic Cooling and Heating Mode will activate “Cooling with Autofan Mode” and “Heating with Autofan Mode” respectively.

• When the Auto Mode is started with SPT +/-0oc, the unit will not select Auto Heat or Auto Cool mode immediately. Instead, the unit will be in a temporary Fan Mode with IFAN operating at low speed. The proper Auto Heat mode or Auto Cool will be started whenever the RT reaches SPT-1oc or SPT+1oc respectively.

• For RC & SH units, Mode change between Auto Heat & Auto Cool Modes is possible only after the COMP has been OFF during the last T minutes.

Mode Change time, TAuto Cool to Auto Heat 3 minAuto Heat to Auto Cool 4 min

• When unit is changed form Cool/Dry mode to Auto Mode, the unit

will continue to operate at (Auto) Cool Mode until the conditions for switching from Auto Cool to Auto Heat are satisfied.

Similarly, when unit is changed from Heat Mode to Auto Mode, the unit will continue to operate at (Auto) Heat Mode until the conditions for switching from Auto Heat to Auto Cool are satisfied.

Protects the Outdoor coil from ice formation by controlling COMP & RV operation.

Scope

This new deicer is designed to operate at extreme temp conditions. The deicing cycle could be triggered from: 1. OCT temp and time between two consecutive deicing cycles. 2. Detection of ice forming by change of the OCT temp.

Both algorithms adjust the time between deicing cycles to optimize the A/C performance. The algorithm will automatically increase the time between deicing cycles and reduce the deicing cycle as needed. The algorithm uses EEPROM data to operate.

Control function

• Starts or stops the unit operation after pre-set time. If RC-1 is used, the timer setting will be (0.5 - 24 Hr) from the moment the timer is set. The minimum resolution is 30 minutes.

If RC-2 or later version of remote controls is used, the timer setting will be (0:00 - 23:50) real time with 10 minutes resolution.

• After power failure, all pre-set timers are cleared. The system is forced to STBY mode and the Timer LED indicator is blinked to indicate the situation. The LED keeps blinking until the timer settings can be reloaded from a R/C message.Note: If all timers are inactive, the system will not be forced OFF after the power failure. The last OPER/STBY status will be loaded from the EEP instead.

• When the A/C receives any valid message from a R/C, the current ON/OFF timer settings will be replaced by the new timer settings in the R/C message.Note: The following timer related operations will not affect the A/C operating mode (Heat/Cool/Auto/Dry/Fan) setting.• Set ON/OFF timer• Clear ON/OFF timer• R/C ON Timer is time-up• R/C OFF Timer is time-up

E.g. When a STBY A/C unit (with Cool Mode setting in its EEP) is turned on by the ON-TIMER of a R/C with heat mode setting, the A/C will start in Cool Mode.

The Sleep mode is activated by using the sleep button on the R/C. In Sleep Mode, the unit will automatically adjust the SPT to turn up/down the room temperature (RT) gradually to provide maximum comfort to the user in sleep.

Sleep is treated as TIMER function. Therefore, the TIMER LED is activated similar to TIMER function.

12.12.1 Adjustment in Sleep Mode1. in cool, auto cool or dry modes, the SPT adjustment is positive (from 0 to +3oc).2. In heat or auto heat modes, the SPT adjustment is negative (from 0 to -3oc).3. In other modes, there is no SPT adjustment.

4. The SPT adjustment is cancelled when the Sleep mode is cancelled.

Note: If Off-timer is active, the unit may go to SB before or after 7 hours of sleep operation.

12.12.2 Time adjustment in Sleep Mode The user can make use of the Off-Timer to extend the Sleep Time from 7 hours to 12 hour (max). The operation of the new “Extended Sleep Mode” is illustrated by the graphs below.

Case 1 is the Standard Sleep Mode, which is the only sleep mode in previous version of MCU. The A/C unit simply works for 7 hours, then goes to SB.

Case 2 is the new Extended Sleep Mode. If an active Off-Timer is set to turn off the A/C between 7-12 hour, relative to the starting of Sleep, the Sleep time is extended.

And, instead of going to SB at the 7th hour, the A/C will work until reaching the Off-time.

Case 3 is an exception to case 2. The Sleep Mode will not be extended to the Off-Time when the Off-Timer is preceded by an On-Timer, which is also between 7-12 hour.

COOL Cools, dehumidifies and filters the room air. Maintains the desired roomtemperature.

SLEEP Designed to create comfortable sleeping conditions. When in COOLING mode,the temperature rises one degree centigrade every hour, for to three hours, fromthe start of the mode. The temperature rise prevents the feeling of over-coolingwhile sleeping (when your body is at rest). In HEATING mode the reverse occurs;the air conditioner lowers its temperature one-degree every hour. When in SLEEPmode, the air conditioner will be automatically turned off after have operated forseven hours. The result is a more comfortable and invigorating sleep, which leavesyou feeling fresh and energetic on the next morning.

TIMER Real time control and display, automatically turns the air conditioner ON andOFF according to the time of day setting, ensuring comfort conditions beforereturning home, without wasting electricity. It turns the air conditioner offautomatically when sleeping.

HOT KEEP In HEATING and in AUTO FAN, the fan will be turned off when the compressoris not in operation and will not be restarted, unless the indoor coil reachesadequate temperature. This HOT KEEP feature prevents uncomfortable cold airdrafts. Use of AUTO FAN is, therefore, recommended when the air conditioneris in HEATING mode.

AUTO FAN The air conditioner automatically selects the FAN speed in accordance to with theroom temperature. At the start, the unit operates at high fan speed. As the roomair approaches to the desired temperature, the fan switches to a lower speed forquieter operation.

FAN Recirculates and filters the room air. Maintains constant air movement inthe room.

DRY Dehumidifies and softly cools the room In DRY Mode, the air conditioneroperates at an inceased dehumidifying power. This function is recommendedto be used when temperature is rather low but the humidity is high.

AUTO Automatically switches from COOLING to HEATING or from HEATING toCOOLING, maintaining the desired temperature according to the room conditions.

HEAT Heats and filters the room air. Maintains the desired room temperature.

New Refrigerant Air Conditioner Installation

THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER. R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with the adoption of the new refrigerant, the refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigeration machine oil does not enter into the new type refrigerant R410A air conditioner circuit. To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and installation tools are different from those used for the conventional refrigerant units. Accordingly, special tools are required for the new refrigerant (R410A) units. For connecting pipes, use new and clean piping materials with high pressure fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are some problems with pressure fittings and possible impurities in existing piping.

Changes in the product and componentsIn air conditioners using R410A, in order to prevent any other refrigerant from being accidentally charged, the service port diameter size of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)

In order to increase the pressure resisting strength of the refrigerant piping, flare processing diameter and opposing flare nuts sizes have been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

INSTALLATION/SERVICE TOOLS (ONLY FOR R410A PRODUCT)

CAUTION

Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and protector coating in the U.S's ARI specified rose color (ARI color code: PMS 507).

Also, the "charge port and packing for refrigerant cylinder" requires 1/2 UNF 20 threads per inch corresponding to the charge hose's port size.

As the working pressure is high, it is impossible to measure the working pressure using conventional gauges. In order to prevent any other refrigerant from being charged, the port diameters have been changed.

In order to increase pressure resisting strength, hose materials and port sizes have been changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to confirm the port size.

As working pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur.

The size of opposing flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8.

By increasing the clamp bar's receiving hole size, strength of spring in the tool has been improved.

Used when flare is made by using conventional flare tool.

Connected to conventional vacuum pump. It is necessary to use an adapter to prevent vacuum pump oil from flowing back into the charge hose. The charge hose connecting part has two ports -- one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge may occur and damage the equipment.

Exclusive for HFC refrigerant.
