HI AIR KOREA RCC-1-HD
HI AIR KOREA
New product
The HI AIR KOREA RCC-1-HD is a microprocessor-based control unit designed for automatic refrigeration compressor operation and compressor capacity-control functions in marine air-conditioning and refrigeration installations.
The RCC-1-HD instruction manual describes the unit as a refrigeration compressor control panel printed circuit board designed to control the compressor and its capacity-control solenoid valves. It incorporates motor-current monitoring, over-current protection, suction-line temperature monitoring, compressor running-hour measurement and alarm functions.
The photographed SM MARINE SERVICE™ unit is clearly marked:
Manufacturer / Brand: HI AIR KOREA

The same model is also listed by marine automation suppliers as HIAIR KOREA RCC-1-HD Controller and HIAIR Air Conditioning Control Board.
The RCC-1-HD is the central electronic controller for a compatible refrigeration compressor system.
According to the instruction manual, it is designed to perform automatic refrigeration-compressor control and to operate the associated capacity-control solenoid valves. The unit uses a microprocessor and solid-state circuitry with isolated relay contacts for external interlocks.
In practical shipboard service, the RCC-1-HD can monitor operating conditions and control several important compressor functions from one controller.
The RCC-1-HD integrates multiple compressor-control and monitoring functions.
Documented functions include:
These functions are documented in the RCC-1-HD instruction and operation manual.
The photographed RCC-1-HD has two large 7-segment display areas.
The front panel identifies monitored values as:
CURRENT (AMP)
COUNT (HOUR)
SUCTION TEMP (°C)
The manual explains that, during normal operation, the display can indicate motor current and suction-line coolant temperature. Under system-off conditions, the controller can display compressor run hours and suction temperature.
This allows engineers to check important refrigeration-compressor operating information directly from the controller.
One of the most important RCC-1-HD functions is compressor motor-current monitoring.
The manual states that the RCC-1-HD incorporates a current monitoring circuit that also provides an over-current protection function.
A motor-current trip parameter can also be programmed through the controller interface.
This makes the RCC-1-HD more than a simple start/stop relay panel—it actively monitors an important compressor operating parameter.
The controller incorporates a compressor run-hour meter.
This is important for vessel planned-maintenance programs because compressor operating hours may be used to schedule inspections, oil changes and overhaul work.
The front panel's COUNT (HOUR) indication corresponds to this running-hour monitoring function.
The RCC-1-HD monitors the temperature of the coolant/refrigerant suction line, with the value displayed on the front panel.
The photograph clearly shows:
SUCTION TEMP (°C)
and the operating manual confirms suction-line temperature monitoring as part of the controller's normal display functions.
A faulty sensor, wiring problem or abnormal refrigeration operating condition can therefore lead to incorrect temperature indication or related alarms.
The photographed controller includes four capacity-control indicators:
1ST
2ND
3RD
4TH
The RCC-1-HD manual documents capacity-control solenoid valve operating delay parameters and describes the controller as specifically designed to control compressor capacity solenoid valves.
This staged arrangement enables the refrigeration compressor to increase or reduce capacity in accordance with the programmed control logic and system demand.
Exact solenoid-valve arrangement can vary by compressor and plant design, so vessel drawings should be followed for the particular installation.
A dedicated HEATER pushbutton and indicator are provided on the front panel.
The manual states that the heater can be switched ON or OFF by pressing the HEATER switch.
In a refrigeration-compressor installation, this function may be used for the appropriate compressor heater arrangement specified by the plant manufacturer.
The exact connected heater circuit should always be confirmed from the vessel wiring diagram.
The photographed RCC-1-HD includes visible indications for:
STAN-BY
ANTI-RECYCLING
These are important compressor-protection and operational functions.
An anti-recycling function typically prevents rapid compressor restart after stopping, helping protect refrigeration machinery from repeated short-cycle starts.
The exact delay logic and programmed value should be confirmed from the applicable RCC-1-HD parameter settings and vessel documentation.
The controller provides a dedicated red ALARM LED.
The operating manual states that alarm conditions are indicated visually and that the alphanumeric display can show a corresponding alarm code to help identify the affected circuit.
For troubleshooting, technicians should record the displayed code before resetting the controller.
Do not repeatedly reset an alarm without identifying its cause.
The RCC-1-HD supports programmable operating parameters.
According to the manual, programming is carried out through the MODE/SET, UP and DOWN switches. Parameter values are stored in an EEPROM, allowing programmed information to remain stored even when electrical power is removed.
Typical programming procedure involves stopping the compressor, entering the parameter mode, selecting a setting, changing the value and storing the new setting.
Because incorrect parameter settings could affect compressor safety and capacity control, only qualified personnel should modify controller settings.
A marine A/C plant document identifies:
Air-Cond. Plant – HI AIR KOREA
and includes an RCC 1HD Control Panel Instruction & Operation Manual. The document also specifies pressure-control, temperature and compressor-capacity settings for the associated plant.
This confirms the RCC-1-HD's direct application in shipboard air-conditioning/refrigeration systems.
A separate equipment record also lists RCC-1-HD Controller under an A/C plant reference, further supporting its marine HVAC application.
The model appears online under more than one commercial brand description.
Current marine listings identify it as:
HIAIR KOREA RCC-1-HD Controller
while some listings describe it as:
HI-PRES RCC-1-HD Controller / Controller PCB.
For SEO and sourcing, both descriptions are useful.
However, a buyer should match the actual label, controller model, PCB arrangement and vessel documentation rather than assuming every HI-PRES/HIAIR-labelled RCC-1-HD is automatically identical in configuration.
Check the controller's incoming power supply, upstream fuse/breaker, connector seating and associated control-panel wiring.
If supply is present but the displays and LEDs remain inactive, the controller PCB may require further testing or replacement.
Check whether:
POWER is ON,
the controller is not in an active ALARM,
the ANTI-RECYCLING timer is active,
external safety interlocks are healthy,
and the compressor starter circuit is available.
Do not bypass refrigeration safety interlocks merely to force a compressor start.
Read and record the displayed alarm code before pressing STOP/RESET.
The RCC-1-HD manual confirms that system alarm conditions can be represented by alphanumeric codes on the display.
The alarm code should then be checked against the applicable controller manual.
Inspect the motor-current sensing circuit, wiring and controller connections.
Because the RCC-1-HD uses motor-current monitoring for both indication and over-current protection, an incorrect current input may affect normal operation.
Inspect the temperature sensor, cable and terminal connections.
Compare the controller reading with an independent calibrated thermometer if appropriate.
Check:
The RCC-1-HD controls capacity solenoid valves, so both the electronic controller and the mechanical/refrigeration side need to be checked.
The controller uses EEPROM memory and should retain programmed information when power is removed.
If stored values repeatedly change or become corrupted, the controller may require specialist diagnosis.
