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 medium (M) to high (H), 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 "preforming initial settings" in the remote control instruction
manual.
Example 4:
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 5:
To increase the remote control air ventilation rate setting from
Medium to High, set the same numbers as shown in example 2 using
the remote controller for HRV.
Set the switches of 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 switches 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
"Local setting" on page 10 .
■
When the remote controller for HRV, 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".
Linked control with more than two groups
■
Mount the optional
KRP2A61 Adapter PCB for
remote control on the
electric component
mounting base of one HRV
unit.
■
A maximum of 64 air
conditioners and HRV
units can be connected to
the F1 and F2 terminals.
■
Use the remote controller
of the air conditioner to
make the initial settings.
