Features of your new product

Energy Recovery Ventilation

The product helps save energy and drive down operation costs of heaters and coolers by recycling thermal energy (energy load) eciently.

Interlocked operation with DVM

Controls of interlocked operation for energy saving, One remote controller can be used with air conditioners.

Mounted for DX-coil unit for outdoor air treatment

This improves the dry and cooling eect in the summer and humidifying eect in the winter.

Humidity Control

Fresh air conditions are guaranteed by recovering moisture in winter while exhausting it in summer. The high eciency Humidier element can be mounted.(Optional product)

Low Noise and Low Power

With highly ecient motor and optimized system design, operation noise and electric consumption is minimized.

The high eciency lter

This protects the heat exchange element and cleans the polluted outdoor air before it enters the indoor room.

Operation at Cold Area

Optimized automatic ventilation operation is conducted to prevent condensation and air volume reduction.

Clean-UP operation

Prevent the odor and dust of other places such as bathroom and kitchen from entering inside by making supply air greater than the exhaustion air. (You can reverse this procedure to make the exhaustion air bigger than the supply air.)

How to use this unit

This unit should be used with air conditioners. Air conditioning is impossible only by this unit, because this unit does not have temperature control function. (It’s capacity is too small in order to control the room temperature to the whole) And should be operated in combination with standard indoor units. (Interlocked operation) Independent operation is possible, however, temperature setting by remote controller is impossible. In this ON/OFF operation by thermostat depends on factory setting, however, this value is changeable by installation/service mode on site. Model selection should be done not by cooling capacity but by ventilating air ow rate.

Refer to following capacities when using the product with outdoor unit: RHF050KHEA - 3.6kW, RHF100KHEA - 7.1 kW

Checking before use

Checking Up the Sub Power Supply

The sub power supply is a device to prevent electric leakage due to the over current. Install the sub power supply separately near the unit and turn it o when you clean the unit or you do not use the unit for a long period of time.

 Turn on the sub power supply which is installed separately.

- The sub power supply is not supplied with the unit. Purchase the sub power supply individually

• If the circuit breaker (MCCB, ELB) is installed, the sub power supply does not need to be installed mandatorily.

Install & Operation Ranges

Install condition Outdoor air condition Indoor air condition

0~40°C, 80%RH below -15~40°C, 80%RH below 0~40°C, 80%RH below

• If the unit is operated under the condition other than are indicated, it may not operate due to the protective device in the unit. Especially, if outside temperature is under -15°C, the unit does not operate at all.

• Do not operate the unit when typhoon comes. Water may get in the room through the unit due to the rain and heavy winds.

• Avoid operating the unit in indoor or outdoor with high temperature and humidity since dew may form on the internal part of the product, including the heat exchanger. Especially avoid using it during the long rainy period in the summer.

Maintaining your product

Internal protections via the unit control system



This internal protection operates if an internal fault occurs in the product.

Type Description

Against cold air The internal fan will be o to against cold air when the heat pump is heating.

De-frost cycle The internal fan will be o to against cold air when the heat pump is heating.

Anti-protection of

internal battery

Protect compressor

• If the heat pump is operating in Heat mode, De-ice cycle is actuated to remove frost from an outdoor unit that may have deposited at low temperatures. The internal fan is switched o automatically and restarted only after the de-ice cycle is completed. When the outdoor air suction temperature becomes lower than -10°C, the unit is changed to intermittent operation to prevent freezing of the heat exchanger element and dew condensation within the unit.

The compressor will be o to protect internal battery when the product operates in Cool mode.

The product does not start operating immediately to protect the compressor of the outdoor unit after it has been started.

Tips on using product

Here are some tips that you would follow when using your product.

TOPIC RECOMMENDATION

Heat-EX Mode • Energy loss is minimized by recovering energy exhausted when indoor heating and cooling

Quiet Mode • This allows you to have quiet sleep and fresh air while sleeping.

• The ERV operation lamp will also be less bright.

Outing Mode • This allows you to operate the ERV while you are away from home.

• If the operational status is changed by another controller, the Outing mode is canceled.

By-Pass Mode • The ventilation method is used when temperature gap of indoor and outdoor is not big.

• Outdoor air ows into indoor.

Auto Mode • The air is automatically changed depending on the degree of pollution in the indoor air.

Energy saving • Make operating condition for optimized energy saving.

Clean up • Prevent the odor and dust of other places such as bathroom and kitchen from entering inside by

Cooling / Heating • You can have cooling and heating operation through the DX-COIL.

Frost & De-frost • When the product runs in Heat mode, due to temperature dierence between the unit and the

High indoor/outdoor temperatures

Power failure • If a power failure occurs during the operation of the product, the operating immediately stops

Protection mechanism

making the supply air greater than the exhaustion air. (You can reverse this procedure to make the exhaustion air bigger than the supply air.)

• This unit should be used with air conditioners. Air conditioning is impossible only by this unit, because this unit does not have temperature control function. (It’s capacity is too small in order to control the room temperature to the whole) and should be operated in combination with standard indoor units.

• When a remote controller is only connected to the ERV with DX-COIL, independent operation is possible. However, temperature setting by remote controller is not possible.

• In this ON/OFF operation by thermostat depends on factory setting. However, this value is changeable by installation/service mode on site.

outside air, frost will form.

If this happens:

- The product stops heating.

- The product will operate automatically in De-ice mode for 10 minutes.

- The steam produced on the outdoor unit in De-ice mode is safe.

No intervention is required; after about 10 minutes, the product operates again normally.  The unit will not operate when it starts to de-ice.

• If both indoor and outdoor temperatures are high and the product is running in Heat mode, the outdoor unit’s fan and compressor may stop at times. This is normal; wait until the product turns on again.

and unit will be o. When power returns, the product will run automatically.

• After the compressor has stopped or the power supply has been switched on, the compressor will not run for 3 minutes for its protection therefore cool/warm air does not come out of the unit immediately.
