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) efficiently.

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 effect in the summer and humidifying effect in the winter.

Humidity Control

Fresh air conditions are guaranteed by recovering moisture in winter while exhausting it in summer.

The high efficiency Humidifier element can be mounted.(Optional product)

Low Noise and Low Power

With highly efficient motor and optimized system design, operation noise and electric consumption is minimized.

The high efficiency filter

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 flow rate.

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

RECOMMENDATION

• Energy loss is minimized by recovering energy exhausted when indoor heating and cooling

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

• The ERV operation lamp will also be less bright.

• 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.

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

• Outdoor air flows into indoor.

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

(Available only when the additional CO

2

sensor is installed)

• Make operating condition for optimized energy saving.

• Prevent the odor and dust of other places such as bathroom and kitchen from entering inside by making the supply air greater than the exhaustion air.

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

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

• 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.

• When the product runs in Heat mode, due to temperature difference between the unit and the 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.

• If a power failure occurs during the operation of the product, the operating immediately stops and unit will be off. 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.

• Select the power cable in accordance with relevant local and national regulations.

• Wire size must comply with local and national code.

• For the power cable, use the grade of H07RN-F or H05RN-F materials.

• You should connect the power cable into the power cable terminal and fasten it with a clamp.

• The unbalanced power must be maintained within 10% of supply rating among whole indoor units.

• If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is exceeded over 10% of supply rating, the indoor unit is protected, stopped and the error mode indicates.

• To protect the product from water and possible shock, you should keep the power cable and the connection cord of the indoor and outdoor units in the iron pipe.

• Connect the power cable to the auxiliary circuit breaker.

An all pole disconnection from the power supply must be incorporated in the fixed wiring(≥3mm).

• You must keep the cable in a protection tube.

• Keep distances of 50mm or more between power cable and communication cable.

• Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must consider another power supplying method.

• The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected from one breaker.

• Use round pressure terminal for connections to the power terminal block.

• For wiring, use the designated power cable and connect it firmly, then secure to prevent outside pressure being exerted on the terminal board.

• Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible.

• Over-tightening the terminal screws may break them.

• See the table below for tightening torque for the terminal screws.

Indoor unit setting

Power and communication cable connectiona

1. Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan.

2. The address of the indoor unit is assigned by adjusting MAIN(SW01, SW02) and RMC(SW03, SW04) rotary switches.

SW01 SW02 SW03 SW04

 The designs and shape are subject to

change according to the model.

SW05 SW06 SW07 SW08 SW09

Setting Main Address

The MAIN address is for communication between the indoor unit and the outdoor unit.

Therefore, you must set it to operate the product properly.

You can set the MAIN address from ‘00’ to ‘99’ by mixing SW01 and SW02.

The MAIN address from ‘00’ to ‘99’ should differ from each other.

Check the indoor unit address on the plan that you are to install and set the address according to the plan.

• You may not need to set main address if you selected Auto Address Setting from the outdoor unit: see details on the outdoor unit installation manual.

For Example When MAIN address is set as "12".

Setting RMC Address

The SW03, SW04 RMC switch is the address setting switch for controlling the indoor unit with the centralized controller.

You must set the SW03,SW04 and K2 switch when using the centralized controller.

You don't have to set the SW03 and SW04 RMC switch when not suing the centralized controller.

For Example When RMC address is set as "12".
