CONTROL SYSTEM for PNXA 9 / 12
11.1
General Functions and Operating Rules
The DCI software is fully parametric.
All the model dependent parameters are shown in Blue color and with Italic style [parameter].
The parameters values are given in the last section of this control logic chapter of the service
manual.
11.1.1
System Operation Concept
The control function is divided between indoor and outdoor unit controllers. Indoor unit is the
System ‘Master’, requesting the outdoor unit for cooling/heating capacity supply. The outdoor unit is
the system 'Slave’ and it must supply the required capacity nless it enters into a protection mode
avoiding it from supplying the requested capacity.
The capacity request is transferred via indoor to outdoor communication, and is represented by a
parameter called ‘NLOAD’. NLOAD is an integer number with values between 0 and 127, and it
represents the heat or cool load felt by the indoor unit.
11.1.2
Compressor Frequency Control
11.1.2.1 NLOAD setting
The NLOAD setting is done by the indoor unit controller, based on a PI control scheme.
The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOAD
calculation, the indoor fan speed, and the power shedding function.
NLOAD limits as a function of indoor fan speed:
Indoor Fan Speed Maximum NLOAD Cooling

Indoor Fan Control
10 Indoor fan speeds are determined for each model. 5 speeds for cool/dry/fan modes and 5
speeds for heat mode.
When user sets the indoor fan speed to a fixed speed )Low/ Medium/ High(, unit will operate
constantly at set speed.
When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual speed is set
according to the cool/heat load.
11.1.7.1
Turbo Speed
The Turbo speed is activated during the first 30 minutes of unit operation when auto fan speed is
selected and under the following conditions:
Difference between set point and actual room temperature is bigger then 3 degrees.
Room temperature > 22 for cooling, or < 25 for heating.

Heating Element Control
Heating element can be started if LOAD > 0.8* MaximumNLOAD AND Indoor Coil temperature
<45.
The heating element will be stopped when LOAD < 0.5* MaximumNLOAD OR if Indoor Coil
Temperature > 50.
11.1.9
Outdoor Fan Control
7 outdoor fan speeds are determined for each model. 3 speeds for cool and dry modes, and 3
speeds for heat mode, and a very low speed.
Outdoor fan speed is a function of compressor frequency and outdoor air temperature (OAT).
4 routines for fan control are determined. The control routine selection depends on operation
mode, compressor speed, outdoor air temperature (OAT) and heat sink temperature (HST).

11.1.10
EEV (electronic Expansion valve) Control
EEV opening is defined as EEV = EEV OL + EEVCV
EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode, unit
model and capacity.
EEVCV is a correction value for the EEV opening that is based on the compressor temperature.
During the first 10 minutes of compressor operation EEV CV = 0.
Once the first 10 minutes are over, the correction value is calculated as follow: EEVCV(n) =
EEVCV(N-1) + EEVCTT
EEVCTT is the correction based on the compressor temperature. A target compressor temperature
is set depending on frequency and outdoor air temperature, and the actual compressor
temperature is compared to the target temperature to set the required correction to the EEV
opening.
11.1.11
Reversing Valve (RV) Control
Reversing valve is on in heat mode.
Switching of RV state is done only after compressor is off for over 3 minutes.
11.1.12
Ioniser Control
Ioniser is on when unit is on AND indoor fan is on AND Ioniser power switch (on Ioniser) is on.

NLOAD is calculated according to the difference between actual room temperature and user set
point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be ad8usted automatically according to the calculated
NLOAD.
11.4

NLOAD is calculated according to the difference between actual room temperature and user set
point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be adng to the calculated
NLOAD.
11.4.1
Temperature Compensation
In wall mounted, ducted, and cassette models, 3 degrees are reduced from room temperature
reading (except when in I-Feel mode), to compensate for temperature difference between high and
low areas in the heated room, and for coil heat radiation on room thermistor.
The temperature compensation can be enabled/disabled by shortening of J2 on the indoor unit
controller.

Outdoor Coil Deicing Protection
11.7.6.1 Deicing Starting Conditions
Deicing operation will start when either one of the following conditions exist:
Case 1: OCT < OAT – 8 AND TLD > DI
Case 2: OCT < OAT – 12 AND TLD > 30 minutes.
Case 3: OCT is Invalid AND TLD > DI
Case 4: Unit is just switched to STBY AND OCT < OAT - 8
Case 5: NLOAD = 0 AND OCT < OAT -8
OCT – Outdoor Coil Temperature
OAT – Outdoor Air Temperature
TLD – Time from Last Deicing
DI – Deicing Interval (Time Interval Between Two Deicing)
Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and
is 40 minutes in other cases.
Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of
deicing time. If deicing time is shorter then former deicing time, the deicing interval time will be
increased. If deicing time is longer then former deicing time, the deicing interval time will be
decreased.

12.1.1
General Functions and Operating Rules (for single split models)
The DCI software is fully parametric.
All the model dependent parameters are shown in Blue color and with Italic style [parameter].
The parameters values are given in the last section of this control logic chapter of the service
manual.
12.1.2
System Operation Concept
The control function is divided between indoor and outdoor unit controllers. Indoor unit is the system
‘Master’, requesting the outdoor unit for cooling/heating capacity supply. The outdoor unit is the
system ‘Slave’ and it must supply the required capacity unless it enters into a protection mode
avoiding it from supplying the requested capacity.
The capacity request is transferred via indoor to outdoor communication, and is represented by a
parameter called ‘NLOAD’. NLOAD is an integer number with values between 0 and 127, and it
represents the heat or cool load felt by the indoor unit.
12.1.3
Compressor Frequency Control
12.1.3.1 NLOAD setting
The NLOAD setting is done by the indoor unit controller, based on a PI control scheme.
The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOAD
calculation, the indoor fan speed, and the power shedding function.
NLOAD limits as a function of indoor fan speed:

Indoor Fan Control
10 Indoor fan speeds are determined for each model. 5 speeds for cool/dry/fan modes and 5
speeds for heat mode.
When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate
constantly at set speed.
When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual speed is set
according to the cool/heat load.
12.1.4.1 Turbo Speed
The Turbo speed is activated during the first 30 minutes of unit operation when auto fan speed is
selected and under the following conditions:
• Difference between set point and actual room temperature is bigger then 3 degrees.
• Room temperature > 22 for cooling, or < 25 for heating.
12.1.5
Heating Element Control
Heating element can be started if LOAD > 0.8 * MaximumNLOAD AND Indoor Coil temperature <
45.
The heating element will be stopped when LOAD < 0.5 * MaximumNLOAD OR if Indoor Coil
temperature > 50.

EEV (electronic Expansion valve) Control
EEV opening is defined as EEV = EEVOL + EEVCV
• EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode,
unit model and capacity.
• EEVCV is a correction value for the EEV opening that is based on the Target CTT and
discharge superhea.
• During the first 5 minutes of compressor operation EEVCV = 0.
• Once the first 5 minutes are over, the correction value is calculated as follow: EEVCV =
EEVSH Discharge + EEVTarget CTT
• EEVSH Discharge
For cooling, SHDischargeC = CTT- OMT
For Heating, SHDischargeH= CTT- ICT

• Case 2: OCT<-4 AND TLD>100 minutes
• Case 3: OCT is Invalid AND TLD > DI
• Case 4: Unit is just switched to STBY AND OCT<-DST
• Case 5: compressor is stopped during heating operation, OCT<-DST AND TLD>DI,

CONTROL SYSTEM
DST is defined as:
When OAT>0 or OAT is invalid; then DST=8
When OAT≤0; then DST= round down (-DeicerCoef * OAT) + 8
Deicing interval time when compressor is first started in heat mode is 30 minutes.
Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of deicing
time. If deicing time is shorter than former deicing time, the deicing interval time will be increased. If
deicing time is longer than former deicing time, the deicing interval time will be decreased.

TROUBLESHOOTING
When system enters diagnostics mode, only one fault code is shown. Order of priority is from
the lower to the higher number. Diagnostics is continuously ON as long as power is ON. The
current system operation mode will not be changed.
If no fault occurred in the system, no fault code will be displayed during normal operation
mode. The last fault code will be displayed even if the system has recovered from that fault.
The last fault will be deleted from the EEPROM after the system has exit diagnostics mode.
In diagnostics mode, system fault / status will be indicated by blinking of Filter & Timer LEDs.
The coding method will be as follows:
Filter LED will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds. Timer
LED will blink during the same 5 seconds according to the following Indoor / Outdoor unit tables:

Simple procedures for checking the Main Parts
SM PNXADCI 1-A.1 GB
TROUBLESHOOTING
13.2.1
Checking Mains Voltage.
Confirm that the Mains voltage is between 198 and 264 VAC. If Mains voltage is out of this
range, abnormal operation of the system is expected. If in range check the Power (Circuit)
Breaker and look for broken or loosed cable lugs or wiring mistake(s).
13.2.2
Checking Power Input.
If Indoor unit power LED is unlighted, power down the system and check the fuse of the Indoor
unit. If the fuse is OK replace the Indoor unit controller. If the fuse has blown, replace the fuse
and power up again.
Checking Power Input procedure for the Outdoor unit is the same as with the Indoor unit.
13.2.3
Checking the Outdoor Fan Motor.
Enter Test Mode (where the OFAN speed is high)
check the voltage between two pins( Hi and N ) of connector Controller OFAN, normal voltage
is 220VAC.
13.2.4
Checking the Compressor.
The compressor is brushless permanence magnetic DC motor. Three coil resistance is
same. Check the resistance between three poles. The normal value should be below 0.7
ohm. Pay attention U,V, W are respective to connect to RED,BROWN,BLACK wires.
13.2.5
Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector,
normal voltage is 220VAC.
13.3
Precaution, Advise and Notice Items
13.3.1
High voltage in Outdoor unit controller.
Whole controller, including the wires that are connected to the Outdoor unit controller may
have the potential hazard voltage when power is on. Touching the Outdoor unit controller
may cause an electrical shock.
Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else
into the controller when power is on.
13.3.2
Charged Capacitors
Three large-capacity electrolytic capacitors are used in the Outdoor unit controller.
Therefore, charging voltage (380VDC) remains after power down. Discharging takes about
four minutes after power is off. Touching the Outdoor unit controller before discharging
may cause an electrical shock.
13.3.3
•
•
Additional advises
When disassemble the controller or the front panel, turn off the power supply.
When connecting or disconnecting the connectors on the PCB, hold the whole housing,
don’t pull the wire.
There are sharp fringes and sting on shell. Use gloves when disassemble
