1.1 Safety Cautions
Cautions and
Warnings 
Be sure to read the following safety cautions before conducting repair work.

The caution items are classified into “ Warning ” and “ Caution ”. The “ Warning ” items
are especially important since they can lead to death or serious injury if they are not followed closely.
The “
Caution ” items can also lead to serious accidents under some conditions if they are not
followed. Therefore, be sure to observe all the safety caution items described below.

About the pictograms
This symbol indicates an item for which caution must be exercised.
The pictogram shows the item to which attention must be paid.
This symbol indicates a prohibited action.
The prohibited item or action is shown inside or near the symbol.
This symbol indicates an action that must be taken, or an instruction.
The instruction is shown inside or near the symbol.

After the repair work is complete, be sure to conduct a test operation to ensure that the equipment
operates normally, and explain the cautions for operating the product to the customer

Test conditions are as follows
Notes: 1. Operation sound is measured at 1.5 m below the center the body.
2. Fan speed can be changed over to Low mode or High mode.
3. Operating sound is measured in an anechoic chamber.
Operating sound level generally become greater than this value depending on the operating conditions,
reflected sound, and peripheral noise.
4. The sound level at the air discharge port is about 8 dB higher than the unit’s operating sound.

1. Operation
1.1 Explanation for Systems
This product is operated differently depending on the system configuration.
For the operation of the remote controller for indoor unit and centralized controller, refer to the instruction
manual provided with each unit.
Operation for Each System
System Example Operation Method
Independent
System The remote controller turns on and off the air conditioner and HRV unit.
Combined
Operation
SystemwithVRV
Systems and
Skyair Series
The remote controller for VRV turns on and off
the air conditioner and HRV unit.
If only the HRV unit is used without operating
the air conditioner, set the unit in the “ “
VENTILATION mode.
The ON/OFF and timer operation can not be
performed using the HRV remote controllers.
(The indication of centralized control
“ “ appears on the display.)
Other operations can be performed using the
HRV remote controllers. Starting and stopping
operations of the indoor unit and the HRV unit
can be performed using the indoor remote
controllers.
Centralized
System When the HRV remote controllers is not connected, the Centralized controller controls
the operation of the HRV unit.
WhentheHRVremote controllers is connected,
operation can be started and stopped using the
Centralized controller or the indoor and the
HRV remote controllers.
During the indication of centralized control
“ “ appears on the display, the ON/
OFF and timer operation may not be possible
with the HRV remote controlers. Other
operations can be performed using the HRV
remote controllers.

Operation 11
1.2 Operation with The Remote Control for Air Conditioning Operation HRV Units.
(BRC301B61)
For non-independent systems, starting/stopping operation and timer operation may not be possible.
Use the air conditioner remote control or the Centralized controller in such cases.
Operation for
INDIVIDUAL
SYSTEM
1. Operation lamp
This pilot lamp (red) light up while the unit is in Operation.
2. Operation/Stop button
When pushed once, the unit starts operating.
When pushed twice, the unit stops.
3. Air flow rate changeover button
Air flow rate can be changed over to “ “ [Low] mode or ““[High] mode, “FRESH UP“
[Low FRESH UP] mode, “FRESH UP“[High FRESH UP] mode.
Remote Controller
for HRV
BRC301B61
For “Freshup“operation
When this indication does not show: The volume of outdoor air supplied into the room and that of the room
air exhausted outdoors is equivalent.
For “Freshup“operation,
If it is set to “Fresh up air supply“: The volume of outdoor air supplied into the room is larger than that of
room air exhausted outdoors.
(This operation prevents the odor and moisture from kitchens and toilets from flowing into the rooms.
If it is set to “Fresh up air exhaust“: The volume of room air exhausted outdoors is larger than that of
outdoor air suppied into the room.
(This operation prevents the hospital odor and floating bacteria from flowing out to the corridors.)
