CONTROL SYSTEM
CONTENT
11. CONTROL SYSTEM
11.1 General Functions and Operating RulesThe 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 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.
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 Maximum NLOAD Heating
Indoor Fan Speed Maximum NLOAD Cooling Maximum NLOAD Heating
Low MaxNLOADIF1C MaxNLOADIF1H
Medium MaxNLOADIF2C MaxNLOADIF2H
High MaxNLOADIF3C MaxNLOADIF3H
Turbo MaxNLOADIF4C MaxNLOADIF4H
Auto MaxNLOADIF5C MaxNLOADIF5H
NLOAD limits as a function of power shedding:
Mode Power Shedding OFF Power Shedding ON
Cooling No limit Nominal Cooling
Heating No limit Nominal heating
11.1.3 Target Frequency Setting
11.1.3.1 Target Frequency Setting for DCI 25/35/50/60/72Z
The compressor target frequency is a function of the NLOAD number sent from the indoor controller
and the outdoor air temperature.
Basic Target Frequency Setting:
Up to SW 35V12

Time
Whenever the compressor starts up, after it has been off for more than 45 minutes, the compressor
frequency cannot go below Step1RPS for 3 continuous minutes (this rule comes to ensure oil return
to the compressor).
Step 2
The compressor speed cannot go above Step2RPS once after each compressor start up for 3
continuous minutes (this rule comes to prevent oil exit from the compressor after its start up).
Step 3
The speed cannot go higher than Step3RPS unless it was operating for more than 1 continuous
minutes between Step3RPS – 5 and Step3RPS .
After passing above Step3RPS, this rule is re-applied when passing below Step3RPS-5.

11.1.7 Indoor Fan Control
8 Indoor fan speeds are determined for each model. 4 speeds for cool/dry/fan modes and 4speeds
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.
11.1.8 Outdoor Fan Control
11.1.8.1 Outdoor Fan Control for DCI25/35/50/60
7 outdoor fan speeds are determined for each model. 3 speeds for cool and dry modes, and 3speeds
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).

• Entering Deicing 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
Case 6: OCT<-19 AND TLD>60 minutes
All this condition will exist during 10 seconds
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.

CheCNing system pressures and other thermodynamic measures should be done when
system is in Test Mode (in Test mode, system operates in fixed settings). The performance
curves given in this manual are given for unit performance in test mode when high indoor fan
speed is selected.
Entering test mode:
Set unit to Cool/16 degrees/High indoor fan speed, or Heat/30 degrees/High indoor fan speed,
and enter diagnostics.
12.3 Judgment by Indoor/Outdoor Unit Diagnostics

Enter diagnostics mode - press for five seconds Mode button in any operation mode.
ACNnowledgment is by 3 short beeps and lights of COOL and HEAT LED’s. Then, every short
pressing of Mode button will scroll between Indoor and Outdoor unit diagnostic modes by the
aCNnowledgment of 3 short beeps and lighting of COOL and HEAT LED’s.
During the Outdoor unit diagnostics all four Indoor LED’s (STBY, Operate, Filter and Timer)
are blinking. When Indoor diagnostics is displayed, all four LED’s (STBY, Operate, Filter and
Timer) are ON.

CONTENT
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 Heat & Cool LEDs.
The coding method will be as follows:
Heat LED will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds. Cool
LED will blink during the same 5 seconds according to the following Indoor / Outdoor unit
tables:
Note: 0 – OFF, 1-ON
12.3.1 Indoor Unit Diagnostics
● Alarm Output
The Alarm Output dry contact will be on (closed), when a predefined set faults occur.
The fault set is defined under diagnostics section.
The alarm output will be off (open), when the predefined fault is cleared.
The indoor alarm outputs are defined according to the following table:

12.4 Judgment by MegaTool
MegaTool is a special tool to monitor the system states.
Using MegaTool requires:
• A computer with RS232C port.
• A connection wire for MegaTool.
• A special MegaTool software.
Use MegaTool according to following procedure:
• Setup MegaTool software: copy the software to the computer.
• Connect RS232C port in computer with MegaTool port in Indoor/Outdoor unit controller by
the connection wire.
• Run the software and choose the COM port, you can monitor the A/C system state in
monitor tab.
12.5 Simple procedures for cheCNing the Main Parts
12.5.1 CheCNing 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 cheCN the Power (Circuit)
Breaker and look for broken or loosed cable lugs or wiring mistake(s).
12.5.2 CheCNing Power Input.
If Indoor unit power LED is unlighted, power down the system and cheCN 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.
CheCNing Power Input procedure for the Outdoor unit is the same as with the Indoor unit.
12.5.3 CheCNing the Outdoor Fan Motor.
Enter Test Mode (where the OFAN speed is high)
CheCN the voltage between lead wires according to the normal value as following:
• Between red wire and blaCN wire: 310VDC +/- 20V
• Between orange wire and blaCN wire: 15VDC +/- 1V
• Between yellow wire and blaCN wire: 2-6VDC

12.5.4 CheCNing the Compressor.
The compressor is brushless permanence magnetic DC motor. Three coil resistance is same.
CheCN the resistance between three poles. The normal value should be below 0.5 ohm
(TBD).
12.5.5 CheCNing the Reverse Valve (RV).
Running in heating mode, cheCN the voltage between two pins of reverse valve connector,
normal voltage is 220VAC.
12.5.6 CheCNing the electrical expansion valve (EEV).
The EEV has two parts, drive part and valve. The drive part is a step motor; it is ringed on the
valve. CheCN the drive voltage (12VDC). When Outdoor unit is power on, EEV shall run and
have cliCN and vibration.
12.6 Precaution, Advise and Notice Items
12.6.1 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 shoCN.
Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else into
the controller when power is on.
12.6.2 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 shoCN.
12.6.3 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.
w
• There are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
