• HRV • VKM-GA(M)V1
EXPLANATION OF OPERATION MODE
Cooling mode
While operating in ventilation mode, the unit adjusts
the outside air to the indoor temperature and then
brings it into the room.
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 VRVΙΙΙ-system air conditioner
The unit automatically switches between "
from the VRVΙΙΙ system air conditioner (heating, cooling, fan, and set temperature)
and information from the HRV unit (indoor and outdoor temperatures).
The unit automatically switches between "
an air conditioner (Not producted 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
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's coil increases.
Heating capability decreases and the system goes into defrost operation.
•
The remote controller will read "
•
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.)

•
When the system is installed as shown bellow it is necessary to designate one of the remote controllers
as the master remote controller.
•
Only the master remote controller can select cooling, heating, or automatic operation (the last only on
simultaneous cooling/heating systems).
•
The displays of slave remote controllers show "

However, it is possible to changeover to program dry with slave remote controllers if the system is in
cooling operation set by the master remote controller.
