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 flows into indoor.
Auto Mode
• 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)
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
making the supply air greater than the exhaustion air.
(You can reverse this procedure to make the exhaustion air bigger than the supply air.)
Cooling / Heating
• 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.
Frost & De-frost
• 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.
High indoor/outdoor
temperatures
• 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.
Power failure
• 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.
Protection
mechanism
• 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.
