INTRODUCTION
1.1
General
The new DLF DC INVERTER concealed split unit range comprises the RC (heat pump)
models as follow:
● DLF 25
● DLF 35
● DLF 50
● DLF 60
● DLF 72
Remote control compatibility
The DLF unit is compatible with remote controls RC3, RC4, RCW1, RCW2, and RC7.
Unlike standard units (fix RPM) that are selected according to their nominal capacity to
overcome the maximum required load; DC Inverter units can be selected to a smaller
nominal capacity range unit.
It made possible due to the ability of inverters to reach a much higher capacity level
(indicated as Maximum Capacity) which is around 115-130% of the nominal capacity.
1.2
Main Features
High level DC inverter system combined with concealed indoor units.
The system consists of high technology DC Brushless compressor, outdoor and indoor
fan motors.
The system adopts new ODP free refrigerant R410A and other environmental regulations
such as RoHS, WEEE, etc.
We believe this is the most suitable solution for residential and light commercial air
conditioning.
The indoor with only 200 mm height and together with the integrated water pump allows
best fit into very low ceiling space.
The units’ unique feature is the option of install the unit in horizontal or vertical position
without any additional work.
The unit low noise level (up to 25 DBA) fits perfectly for application as hotels, bed room
and small offices.
The DLF series benefits from the most advanced technological innovations, namely:
Variable cooling and heating capacity from 30% to 115% (of rated capacity)
High COP
Low noise levels in both indoors and outdoors
Extreme low silhouette, only 200mm.
Pre-charged system up to 30m
Tubing up to 50m length and 30m height difference
Networking connectivity
Dry contact output – Alarm
Ready for base heater and crank case heater installation including software support
HMI Display consists of 7-segments shows system diagnostics and setup (in some
models only)
Monitoring software (PC port for high level service)
Operating range cooling: From -10ºC to 46ºC outdoors
Operating range heating: From -15ºC to 24ºC outdoors

13.1
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.
13.1.1
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.
13.1.2
13.1.2.1
Compressor Frequency Control
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.

Compressor starting control for DCI72Z
Step 1
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.

EEV (Electronic Expansion Valve) Control
13.1.9.1 EEV Control for DCI25/35/50/60
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 compressor temperature.
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(n) = EEVCV(n-1)
+ EEVCTT
EEVCTT is the correction based on the compressor temperature. A target compressor temperatureзs
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 EEVopening.
13.1.9.2
EEV Control for DCI72Z
The target EEV value is the sum of open loop value (OL) and a result of the accumulative correction
values (CV).
EEV EEVOL EEVCV
Initial EEV value is set according to compressor frequency and according to indoor and outdoor
model
The corrective value is calculate every 30 sec the EEV corrective value is set to keep the discharged
super heat temperature between 20º to 30º in cooling and 12º to 20º in heating.

13.1.13.1 Temperature Compensation
In 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

13.1.13.2 Indoor Fan Control in Heating Mode
Indoor fan speed depends on the indoor coil temperature:
13.1.14
Auto Cool/Heat Mode
When in auto cool heat mode unit will automatically select between cool and heat mode according to
the difference between actual room temperature and user set point temperature (.T).
Unit will switch from cool to heat when compressor is off for 3 minutes, and .T < -3.
Unit will switch from heat to cool when compressor is off for 5 minutes, and .T < -3.
13.1.15
Dry Mode
As long as room temperature is higher then the set point, indoor fan will work in low speed and
compressor will work between 0 and MaxNLOADIF1C Hz.
When the room temperature is lower than the set point, compressor will be switched OFF and indoor
fan will cycle 3 minutes OFF, 1 minute ON.
13.1.16
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.

Outdoor Coil Deicing Protection
13.1.19.1 Outdoor coil Deicing Protection For DCI25/35/50/60/72Z
•
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.

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 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

the connection wire.
14.5
Simple procedures for checking the Main Parts
14.5.1
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).
14.5.2
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.
14.5.3
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:
•
•
•
14-6
Between red wire and black wire: 310VDC +/- 20V
Between orange wire and black wire: 15VDC +/- 1V
Between yellow wire and black wire: 2-6VDC
CONTENT
SM DLF 1-A.1 GB
TROUBLESHOOTING
14.5.4
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 0.5 ohm
(TBD).
14.5.5
Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector,
normal voltage is 220VAC.
14.5.6
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.
14.6
Precaution, Advise and Notice Items
14.6.1
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 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.
14.6.2
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 shock.
14.6.3
•
•
w
•
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.

APPENDIX A
Installation/Service Tooling for R410A
Changes
Gauge manifold
As the working pressure is high, it is impossible
to measure the working pressure using
conventional gauges. In order to prevent any
other refrigerant from being charged, the port
diameters have been changed.
Charge
hose
In order to increase pressure resisting strength,
hose materials and port sizes have been
changed (to 1/2 UNF 20 threads per inch).
When purchasing a charge hose, be sure to
confirm the port size.
Electronic scale for
refrigerant charging
As working pressure is high and gasification
speed is fast, it is difficult to read the indicated
value by means of charging cylinder, as air
bubbles occur.
Torque wrench (nominal
dia. 1/2, 5/8)
The size of opposing flare nuts has been
increased. Incidentally, a common wrench is
used for nominal diameters 1/4 and 3/8.
Flare tool (clutch type)
By increasing the clamp bar's receiving hole
size, strength of spring in the tool has been
improved.
Gauge for projection adjustment
Used when flare is made by conventional flare
tool.
Vacuum pump adapter & check valve
Connected to a conventional vacuum pump. It
is necessary to use an adapter to prevent
vacuum pump oil from flowing back into the
charge hose. The charge hose connecting part
has two ports - one for conventional refrigerant
(7/16 UNF 20 threads per inch) and one for
R410A. If the vacuum pump oil (mineral) mixes
with R410A a sludge may occur and damage
the equipment.
Gas leakage detector
Exclusive for HFC refrigerant.
Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and
protector coating in the U.S's ARI specified rose color (ARI color code: PMS 507). Also,
the "charge port and packing for refrigerant cylinder" requires 1/2 UNF 20 threads per inch
corresponding to the charge hose's port size.

APPENDIX A
CAUTION R410A Air Conditioner Installation
THIS AIR CONDITIONER ADOPTS THE
NEW HFC REFRIGERANT (R410A)
WHICH DOES NOT DESTROY OZONE
LAYER. R410A refrigerant is apt to be
affected by impurities such as water,
oxidizing membrane, and oils because the
working pressure of R410A refrigerant is
approx. 1.6 times of refrigerant R22.
Accompanied with the adoption of the new
refrigerant, the refrigeration machine oil has
also been changed. Therefore, during
installation work, be sure that water, dust,
former refrigerant, or refrigeration machine
oil does not enter into the new type
refrigerant R410A air conditioner circuit. To
prevent mixing of refrigerant or refrigerating
machine oil, the sizes of connecting
sections of charging port on main unit and
installation tools are different from those
used for the conventional refrigerant units.
Accordingly, special tools are required for
the new refrigerant (R410A) units. For
connecting pipes, use new and clean piping
materials with high pressure fittings made
for R410A only.
Moreover, do not use the existing piping
because there are some problems with
pressure fittings and possible impurities
in existing piping.
Changes in the product and
components
In air conditioners using R410A, in order
to prevent any other refrigerant from
being accidentally charged, the service
port diameter size of the outdoor unit
control valve (3 way valve) has been
changed. (1/2 UNF 20 threads per inch).
In order to increase the pressure
resisting strength of the refrigerant
piping, flare processing diameter and
opposing flare nuts sizes have been
changed. (for copper pipes with nominal
dimensions 1/2 and 5/8).
In case of pipes welding please make
sure to use dry Nitrogen inside the
pipes.
Use copper tube of special thickness for
R410A:
1/4”-1/2” 0.8 mm
5/8”-3/4” 1 mm
Do not vent R410A into atmosphere: R410A is a fluorinated greenhouse gas, covered by
Kyoto Protocol, with a Global Warming Potential (GWP) = 1730
