EXPLANATION OF OPERATION MODE
Note
•
This unit cannot control room temperature. If this is needed, do not install the HRV unit alone, but rather
install another indoor unit.
EXPLANATION OF VENTILATION MODE
Note
•
These icons below are displayed on the remote controller BRC1D527.
Automatic mode
: When combined with a VRV system air conditioner
The unit automatically switches between “
” and “
” based on information
from the VRV system air conditioner (heating, cooling, fan, and set temperature) and
information from the HRV unit (indoor and outdoor temperatures).
The unit automatically switches between “
” and “
” when it is combined with
an air conditioner (Not produced by Daikin) and based on only the information from
the HRV unit (indoor and outdoor temperatures) when the HRV unit is operating
alone.
Total heat exchange mode
: Outdoor air passes through the heat exchange element and heat
exchanged air is sent into the room.
Bypass mode
: In this mode outdoor air does not through the heat exchange element, but rather sent
into the room as is.
EXPLANATION OF HEATING OPERATION
Defrost operation
•
In heating operation, freezing of the outdoor unit coil increases. Heating capability decreases and the
system goes into defrost operation.
•
The remote controller will read “
” until the hot air starts blowing.
•
It returns to the heating operation again after 6 to 8 minutes (10 at the longest).
•
During defrost operation, the fans of the unit continues driving (factory setting).
The purpose of this is to maintain the amount of ventilation and humidifying.
•
The change of the layout in the room should be examined when the cold draft from air supplying
opening is feared.
•
Though the fan can be stopped by the setting of remote controller.
Do not stop the fan in the place where no ventilation by stopping the fan may cause the influence of
diffusion of air which it is dirty and moisture into another room, or the inflow from outside the room.
(outflow such as viruses from the sickroom, or smell leakage from the rest room, etc.)
Contact your dealer for details.

The remote controller will read “
” until the hot air starts blowing, e.g. at the start of heating
operation.
