1. INTRODUCTION
1.1 General
The new DLS DC INVERTER split unit range comprises the following RC (heat pump)
models:
• DLS 18
• DLS 24
• DLS 30
• DLS 36
• DLS 43
Remote control compatibility
The units are compatible with remote controls RC3, RC4, RC7, RC8
Inverter description
Unlike standard units (x 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 Technology
• Sine wave DC Compressor drive.
• DC-BL-SL (DC Brush-Less Sensor less) Inverter Compressor.
• DC-BL Inverter Outdoor and Indoor Fan.
• Fuzzy Logic Adaptive Control.
System Features
• ECO Design ready
• Variable cooling and heating capacity from 30% to 115% (of rated capacity).
• High COP “A-B” class energy rating (Most units).
• Low noise levels.
• Pre-charged system up to 30m.
• Tubing up to 70m length / 30m height difference (most units).
• Networking connectivity.
• Dry contact inputs:
♦ Forced Standby.
♦ Night mode (for silent operation).
♦ Power Shedding (to control maximum power consumption).
• Dry contact output:
♦ Alarm
♦ Base Heater
♦
Crank Case Heater
• HMI Display consists of 7-segments shows system diagnostics and setup.

• Heating operation at outdoor temperature down to -15°C.
• Up to 100Pa External static pressure (most units).
1.3 Indoor Unit
1.3.1 DLS
The DLS DCI indoor unit is a low silhouette ducted unit, and can be easily tted to
many type of residential and commercials applications.
• Low silhouette units 260/300 mm height.
• High technology plastic fan and fan housing.
• Drain pool at bottom of unit with internal downward slope.
• Over-ow switch, stops compressor operation in case of a blocked drainage.
• Integrated water pump
• Bended coil hydrophilic coated aluminum ns.
• 3-speed fan motor and an extra speed in case a higher external static pressure
required.
• Tubing connections at the back of the unit to allow easy outlet to both sides of the
unit.
• Easy installation and service access.
• Infrared remote control with liquid display unit (LCD).
• Field options:
(1) External water pump.
(2) Airconet connection.
(3) Plenum kit for connection of exible duct hoses at air outlet.
1.4 Filtration
• The unit is equipped with pre lters.
• Easy and versatile access, rear or bottom, can be easily adjusted by the installer.
1.5 Control
The micro processor indoor controller, and an infrared remote control, supplied as
standard, provides complete operating function and programming.
For further details, please refer to the Operation Manual, Appendix A.
1.6 Outdoor Unit
The DCI outdoor units can be installed as oor or wall mounted units by using a wall-
supporting bracket. The metal sheets are protected by anti- corrosion paint work
allowing long life resistance. All outdoor units are pre-charged. For further information,
please refer to the Product Data Sheet, Chapter 2.
• Compressor mounted in a soundproofed compartment.
• Improved 3-blades axial fans for noise reduction.
• Outdoor coil with hydrophilic ns optimized for operation with R410A refrigerant.

(a) Power supply can be connected in both ways:
vTo outdoor unit to supply both outdoor and indoor unit.
vTo outdoor unit and to Indoor unit separately.
(b) Communication wires must be separated from the power wires and should be shielded type, earth connected at
both ends.
(c) Inrush current is the current when power is up (charging the DC capacitors at outdoor unit controller).
(d) Starting current is the current peak when starting the compressor.
NOTE:
Power wiring cord should comply with local lows and electrical regulations requirements.

12.3.2 Communication with Indoor Unit
12.3.2.1 CommunicationFailuresDenition
12.3.2.1.1 ‘Bad Communication’ fault
The system keeps a balance of a good/bad communication packet ratio. When the ratio becomes high the system
enters ‘Bad Communication’ fault. The system recovers from that fault when the ratio becomes small again.
When in ‘Bad Communication’ fault, system continues its normal operation and fault code is shown in diagnostics.
12.3.2.1.2 ‘No Communication’ fault
If no legal transmission or no message received for 30 seconds, system enters ‘No Communication’ fault.
When in ‘No Communication’ fault, the fault code will be shown in diagnostics. In this case, the system will force the
compressor to off.
The system will recover from ‘No Communication’ fault when counter is below 10 and legal massage is received.
1. For the single split communication channel, whenever there is loose in the communication channel,
the ODU unit will be forced to Idle mode.
2. For Multi split communication channel,

12.4 Indoor Unit Control
12.4.1 Load calculation
LOAD is calculated according to the difference between actual room temperature and user set point temperature
by PI control.
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 Maxium NLOAD Cooling Maxium NLOAD Heating
Low MaxNLOADIF1C MaxNLOADIF1H
Medium MaxNLOADIF2C MaxNLOADIF2H
High MaxNLOADIF3C MaxNLOADIF3H

12.4.7.2 Control function
o The Sleep mode is activated by using the SLEEP button on the R/C. In Sleep
Mode, the unit will automatically adjust the SPT to turn up/down the room
temperature (RT) gradually to provide maximum comfort for the sleeping user.
o Sleep is treated as TIMER function. Therefore, the TIMER LED is activated similar
to TIMER function.
o In COOL, AUTO COOL or DRY modes, the SPT adjustment is positive
(from 0 to +3oC).
o In HEAT or AUTO HEAT modes, the SPT adjustment is negative
(from 0 to -3oC).
o In other modes, there is no SPT adjustment.
o The SPT adjustment is cancelled when the Sleep mode is cancelled.
o If OFF-timer is active, the unit may go to SB before or after 7 hours of sleep
operation.

12.5 Run Mode
Run mode is the default operation mode of the system. This is the standard operation mode that is active in eld application
(at customer site).
System can go from run mode to other operation modes through keyboard or serial ports.
12.5.1 Mode Setting
Thermal mode denes the ODU operation mode. There are three possible operation modes:
1. STBY – Standby mode
2. COOL - the unit operate at cooling cycle
3. HEAT - the unit operates at heat pump cycle (deicer will be treated as sub-mode of heat
mode in the thermal Mode setting).
The last mode will be stored in the EEPROM, and it will be restored on system power up, where the default value is
STBY.

Compressor minimum ON and OFF time is 3 minutes except during protections.
12.5.2.2 Compressor Startup
When started, compressor speed reaches certain level (usually 30÷40 RPS) and will not go below that during the
rst 5 minutes except when compressor is forced OFF.
12.5.2.3 Compressor start up fail
If the compressor does not succeed to complete the startup procedure, it retries the startup procedure every 10
second and up to 3 minutes it will report a compressor lock or unusal behavior.

12.5.3 EEV Control
12.5.3.1 EEV General Rules
The EEV is controlled to keep the optimal system performance at all times. It is done by means of discharge
superheat temperature and optimum compressor temperature control.
The target EEV value is the sum of open loop value (OL) and a result of the accumulative correction values (CV).
EEVi = EEVOL

12.5.3.2 EEV initialization procedure
After power up, the EEVs perform initialization procedure while it closed completely and reopened to predened
position.
12.5.3.3 Balance time
During the rst 5 minutes after SB the correction is not calculated. After that the correction value is updated every
EEVCVTConst seconds.
12.5.3.4 Operation Range
The EEV operation range is dened according to the operation mode as following:

12.6.3 Deicing
12.6.3.1 Deicing Starting Conditions
12.6.4.1 Deicing Starting Conditions
Deicing operation will start when either one of the following conditions exist:
Case 1: OCT is 8 degree lower then the ambiant temp and the minimum time from the last deicer is passed.
Case 2: OCT is 12 degree lower then the ambiant temp and 30 minutes from the last deicer wa passed.
Deicing interval time when compressor is rst 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.
In case one of the thermistors is bad the deicer will initiate in predened intervals.
Deicer may accure also when the unit switch to stanby and the OCT is 8 degree lower then ambiant
