12.4.1 COMP operation
For each Mode including POWER OFF & SB, a Min time delay of 3 min
before COMP restarting, excluding DEICING Mode
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 MED
1 T LOW
where in Heat Mode: ∆T = SPT-RT
in Cool Mode: ∆T = RT-SPT

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).

o
c.
b. Thermistor is shorted ­ The thermistor reading is over 75
o
c.
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 3
o
c, 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+/-1
o
c 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 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*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.

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:

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.

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.

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.

The test purpose is to verify that the CPU rise time after power failure is between 1 to 3 sec, test results are indicated on the LEDS : STAND­BY,OPER, TIMER and FILTER turning ON one by one.
The results of the test are coded as follows:
Pass condition:
1 sec - STAND-BY and OPER are turned ON 2 sec - STAND-BY, OPER and TIMER are turned ON

Fail condition:
0 sec - STAND-BY is turned ON 3 sec - STAND-BY, OPER, TIMER and FILTER are turned ON
When the timing reset test is completed, the next test will start automatically.
i. STEP 9: MEMORY TEST (EEPROM)
The test purpose is to check if the memory is functioning correctly. The test result is reported by using the STAND-BY and FILTER LEDS:
LED Indicator Condition for LED to be ON
STAND-BY LED Test passed FILTER LED Test failed
AT THIS POINT THE SELF-TEST IS COMPLETED.
In order to terminate Self-Test mode the User can change the unit setting from COOL Mode, LOW FAN to COOL Mode, MED FAN or to wait without using the remote control for 60 sec.
