12.4.6

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.
Thermistors operation
12.4.6.1
•
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).
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 ΔT 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.

12.4.6.2
Cases for disabling thermistor short/disconnected detection
i.
The detection of thermistor faults (a) and (b) above, are disabled when Deicer
Protection is started. The detection will be enabled again only after (1) the
deicing is completed, and (2) COMP has been restarted and operated for 30
sec.
ii. When all the following conditions are fulfilled:
a.
4.7K Ohm resistor is connected on the OCT
b.
IFAN is OFF
c.
Compressor is ON
d.
ICT < -30 (disconnected)
This condition come to detect and prevent IFAN operation in Deicer in multi spilt
units.
12.4.6.3
i.
Handling the thermistor faults in a COMP unit
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*4
Notes:
• 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.

As a general rule for RC and SH groups, when COMP is ON, excluding

this case, the IFAN will be started at low speed.

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:

Automatic Cooling or Heating - General
• 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.

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.

For WAX, the IFAN is simply forced OFF.

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

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

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.
