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.
11.2
System Operation Concept
The control function is divided into indoor, MSMP and main outdoor unit controllers. MSMP
is a specific PCB in outdoor unit which serves as a bridge between all indoor units and
outdoor unit. It communicates with the outdoor unit as one indoor unit and communicates
with each indoor unit as one outdoor unit. Each indoor unit will send the request to MSMP
for cooling/heating capacity supply. MSMP will deal with all the requests from indoor units
and send an integral capacity request to outdoor unit. The outdoor unit will 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, MSMP and 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 total heat or cool load felt by all the indoor units.
11.3
11.3.1
Compressor Frequency Control
NLOAD setting
The NLOAD setting is done by each indoor unit controller, based on a PI control scheme.
MSMP will deal with request from each unit and send a synthetical NLOAD to the outdoor unit.
The actual NLOAD to be sent to the outdoor unit controller is based on the calculated LOAD from
MSMP 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 cooling/dry/fan modes
and 5 speeds for heating 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.
11.4.1
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.
11.5
Heating Element Control
Heating element can be started if LOAD > 0.8 * Maximum NLOAD AND Indoor Coil
temperature < 45.
The heating element will be stopped when LOAD < 0.5 * Maximum NLOAD OR if Indoor Coil
temperature > 50.
11.6
Outdoor Fan Control
7 outdoor fan speeds are determined for each model. 3 speeds for cooling and dry modes,
and 3 speeds for heating 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, and outdoor air temperature (OAT) and heat sink temperature
(HST).

EEV (electronic Expansion valve) Control
EEVi opening of the ‘i’ indoor unit is defined as EEVi = EEVOLi + EEVCVi
EEVOLi is the initial EEV opening as a function of the compressor frequency, operation
mode, unit model and capacity.
EEVCVi is a correction value for the EEV opening that is based on the compressor
temperature.
During the first 5 minutes of compressor operation EEVCVi = 0.
Once the first 5 minutes are over, the correction value is calculated as follow: EEVCVi(n)=
EEVCVi(n-1) + EEVSHi + EEVCTTi
EEVSHi = EEVminSHi+ EEVdeltaSHi
EEVminSHi is correction for the EEV opening of the ‘i’ indoor unit as of the whole system
superheat.
EEVdeltaSHi is correction for the EEV opening of the ‘i’ indoor unit as of balance between each
unit.
EEVCTTi is the correction for the EEV opening of the ‘i’ indoor unit 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.
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.
11.9
Electro Static Filter (ESF) Control
ESF is on when ESF switch is on, Safety switch is pressed, unit is on, AND indoor fan is on.

11.14.1 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 sensor.
The temperature compensation can be activate or deactivate by shortening of jumper J2 on
the indoor unit controller.

Protections
There are 5 protection codes.
Normal (Norm) – unit operate normally.
Stop Rise (SR) – compressor frequency can not be raised but does not have to be
decreased.
HzDown1 (D1) – Compressor frequency is reduced by 2 to 5 Hz per minute.
HzDown2 (D2) – Compressor frequency is reduced by 5 to 10 Hz per minute.
Stop Compressor (SC) – Compressor is stopped.
The MSMP receives the protection status from each one of the indoor unit. It calculates the
overall outdoor unit protection status based on each ‘i’ indoor unit protection status weight
according to the following average:

11.17.5.1 Deicing Starting Conditions
Deicing operation will start when either one of the following conditions exist:
ƒ Case 1: OCT < OAT – 8 AND TLD > DI
ƒ Case 2: OCT < OAT – 12 AND TLD > 30 minutes.
ƒ Case 3: OCT is Invalid AND TLD > DI
ƒ Case 4: Unit is just switched to STBY AND OCT < OAT – 8
ƒ Case 5: NLOAD = 0 AND OCT < OAT -8
OCT – Outdoor Coil 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.

Checking the Refrigeration System
Checking 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 the two indoor units to Cool/16 degrees/High indoor fan speed, or Heat/30 degrees/High indoor fan speed,
and enter diagnostics. Note: the two indoor units should be set to the same mode and fan speed.

Judgment by MSMP Diagnostics
The MSMP controller has 9 LED’s (4 green Unit LEDs and 5 red Status/Fault LEDs). For the 4 green Unit
LEDs,O-Outdoor unit, A-Indoor unit 1,B-Indoor unit 2,C-Indoor unit 3. For the 5 red Status/Fault LEDs, it should
be read from O-A-B-C-D to get fault numbers. The 4 green Unit LEDs will turn on one at a time and the
corresponding Indoor/Outdoor unit status/fault code will be displayed on the red Status/Fault LEDs. If the unit is
normal (no fault), the green unit LED and the corresponding status will be displayed for 5 seconds and move to
the next green unit LED. On the other hand, if the unit is in fault, the green unit LED and the corresponding fault
will be displayed for 10 seconds, and hence more time to read the fault code.
STBY LED is ON when power is ON.

1.5.1 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).
1.5.2 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.
1.5.3 Checking the PCB.
Appearance inspect: Check discoloration, nick and connection of copper foil, short-circuit and open-circuit,
component soldering, bulgy and distortion of electrolytic capacitor.
Power circuit check: check voltage of every power level (5V, 12V, 15V) printed on back of PCB.
1.5.4 Checking the Outdoor Fan Motor.
Enter Test Mode (where the OFAN speed is high)
Check the voltage between lead wires according to the normal value as following:
Between red wire and black wire: 380VDC +/- 20V
Between orange wire and black wire: 15VDC +/- 1V
Between yellow wire and black wire: 2-6VDC
1.5.5 Checking the Compressor.
The compressor is brushless permanence magnetic DC motor. Three coil resistances are same. Check the
resistance between three poles. The normal value should be 0.642 ohm (U-V), 0.636 ohm (V-W) and 0.652
ohm (U-W). (Environmental temperature 25ºC)
1.5.6 Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector, normal voltage is
220VAC.
1.5.7 Checking 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. Check
the drive voltage (12VDC). When Outdoor unit is power on, EEV shall run and have click and vibration.

Precaution, Advise and Notice Items
1.6.1 High voltage in Outdoor unit controller.
Whole controller, including the wires, 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.
1.6.2 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 three minutes after turned off.
Touching the Outdoor unit controller before discharging may cause an electrical shock. When open the
Outdoor unit controller cover, don’t touch the soldering pin by hand or by any conductive material.
Advise:
1. Open the Outdoor unit controller cover only after five minutes from power down.
2. Measure the electrolytic capacitors voltage before farther checking controller for safety.
1.6.3 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.
There are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
