10.4 General functions

10.4.1 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

10.4.2 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

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:

10.4.3 OFAN operation

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

• In general, OFAN starts together with COMP.

10.4.4 HE operation

• Minimum Heaters ON or OFF time is 30 sec.

• Heaters can be activated only if IFAN is on.

10.4.5 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.

10.4.6 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).

10.4.6.1 Definition of thermistor faults:

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

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.

10-6

CONTROL SYSTEM

Revision Y05-01 Service Manual - MOBILE Series

10.4.6.2 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.

10.4.6.3 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.

10.6.2 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:

10.7.1 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 +/-0

o

c, 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, T
Auto Cool to Auto Heat 3 min
Auto 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.

Control function
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:
To prevent the overflow of condensed water by turning ON the ICP.

Notes:

• When water level reaches LEVEL 4, ICP will be turned ON even if the unit is

in SB mode.

• Under normal operation, at least one of the water level inputs must be active.

If all LEVEL1, LEVEL2&3 and LEVEL4 are inactive, it is assumed that the
connection has been broken and the ICP will be turned ON when the unit is
operating in Cool or Dry mode.

• The operation of the pump is not related to the ON/OFF state of the COMP.

On the contrary, the COMP can be forced to OFF when the water level is high
(level 4).

• The water level inputs are low active. That is, when a water level is reached,

the voltage at the corresponding input pin of the MCU would be changed from
5V (inactive) to 0V (active).

• 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

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.
