4P333249-1A – 2012.11
Installation manual
17
Example 1:
To switch on the pre-cool/pre-heat function, and turn on the HRV unit
60 minutes after the air conditioner is turned on.
• Set the mode No. to “17” for group control, or “27” for individual
control, the setting switch No. to “2” and the setting position No.
to “02”
• Set the mode No. to “17” for group control, or “27” for individual
control, the setting switch No. to “3” and the setting position No.
to “03”
Example 2:
To switch the ventilation air flow to ultra high setting. (The units are
set at the high air flow setting at the factory)
• Set the mode No. to “17” for group control, or “27” for individual
control, the setting switch No. to “4” and the setting position No.
to “02”
Connecting the remote controller for HRV
The remote controller for HRV cannot be used for starting/stopping
operation or for timer operation. (The centralized control indication
will be lit.)
To set pre-cool/pre-heat function settings, change the remote control
air flow rate setting from High (H) to Ultra-High (UH), etc., perform
initial settings from the remote controller for HRV.
Since it will become a two-remote-control system, perform master/
slave setting as shown below.
Refer to “performing initial settings” in the remote control instruction
manual.
Example 3:
To set the pre-cool/pre-heat reservation function to on and have the
HRV start operating 60 minutes after the air conditioner has started,
set the same numbers as shown in example 1 using the remote
controller for HRV.
Example 4:
To increase the remote control air ventilation rate setting from High to
Ultra-High, set the same numbers as shown in example 2 using the
remote controller for HRV.
When the remote controller for HRV is connected, set the switches
on the HRV unit PCB to the default factory settings.
Determination of heating/cooling selection rights for VRV-
systems is performed using the remote controller for HRV.
The heating/cooling selection rights can be enabled or disabled
using the ventilation mode button of the remote controller for
HRV.
This operation cannot be performed with the remote controller
for air conditioner.
Direct duct connection system for 1-group operation system
Line connections and the settings of the switches on the HRV unit
PCB should be the same as for “Standard system for 1-group
system”.
Set the switch of the HRV unit PCB to the default factory settings.
1 Be sure to set the initial settings to Direct duct connection:
Enabled.
When the remote controller for HRV is not yet connected,
initial settings can be performed using the air conditioner
remote control. Set the mode number to “17”, the setting
switch number to “5”, and the setting position number to “02”
according to the procedure in "List of Settings" on page 13.
When the remote controller for HRV is connected, initial
settings should be performed using the remote controller for
HRV. Set the same numbers as described above when using
the remote controller for air conditioner according to the
procedure “Making initial settings” in the remote control
instruction manual.
2 Settings for other HRV functions should be made using the
same method as in “Standard system for 1-group system”.
