(factory default) With connection
2 CO2 / PM2.5 target concentration setting
Target concentration is the concentration at which the fan speed is the highest.
The fan speed is changed automatically in 7 stages according to the CO2concentration and PM2.5 concentration.
The CO2target concentration and PM2.5 target concentration can be changed in the settings below.
DN code SET DATA 0000 0001 0002
790 CO2target concentration 1000 ppm
(factory default) 1400 ppm 800 ppm
793 PM2.5 target concentration 70 μg/m3
(factory default) 100 μg/m340 μg/m3
* Although the fan speed is switched automatically using the set CO2concentration or PM2.5 concentration as a target, the detection
concentration differs depending on the operating environment and product installation conditions etc., so the concentration may go above
the target concentration depending on the operating environment.
* As a general guideline, the CO2concentration should be 1000 ppm or less.
(REHVA (Federation of European Heating Ventilation and Air Conditioning Associations))
* As a general guideline, the PM2.5 concentration (daily average) should be 70 μg/m3or less.
(Ministry of Environment of China)
* The concentration at which the fan speed is the lowest will not change even if the settings above are configured, with the CO2concentration
being 400 ppm, and the PM2.5 concentration being 5 μg/m3.
3 Remote controller display settings
The display of the CO2concentration and PM2.5 concentration on the remote controller can be hidden with the following settings.
DN code SET DATA 0000 0001
561 CO2concentration remote controller display Hide Display
(factory default)
567 PM2.5 concentration remote controller display Hide Display
(factory default)
* Even if the concentration is hidden in the remote controller display, when DN code “560” and “566” control is enabled, automatic fan speed
control is performed.
Refer to section 5 for DN code “560” and “566”.
* If the concentration is hidden, in the event of a sensor failure, the CO2concentration “- - ppm”, PM2.5 concentration “- - μg/m3” will also not
be displayed.
* The display range of the concentration is as follows: CO2: 300 - 5000 ppm, PM2.5: 0 - 999 μg/m3.
* Refer to section 6 for details on the remote controller display in a group connection system.
4 Remote controller concentration display correction
Detection of the CO2concentration and PM2.5 concentration is performed at the RA air path of the heat recovery ventilation unit main body.
As unevenness will also occur in the indoor concentration, a difference between the concentration displayed in the remote controller and the
environmental measurement etc. may result. In such a situation, the concentration value displayed by the remote controller can be corrected.

* The CO2concentration will appear as “- - ppm” if the corrected value is too low.
* If the corrected PM2.5 concentration is negative, it will appear as “0 μg/m3”.
* Correct only the concentration display value displayed by the remote controller.
* Refer to section 6 for details on the remote controller display in a group connection system.

5 Concentration control setting
Automatic fan speed control according to the CO2concentration or PM2.5 concentration can be selected individually.
When both controls are enabled, the unit will run at a fan speed close to the target concentration (higher of the concentrations).
DN code SET DATA 0000 0001
560 CO2concentration control Uncontrolled Controlled
(factory default)
566 PM2.5 concentration control Uncontrolled Controlled
(factory default)
* Both CO2concentration control and PM2.5 concentration control are enabled in the factory default settings, so be extra careful when either
control is disabled as the following faults may occur.
1) If CO2concentration control is disabled and the PM2.5 concentration is maintained at a low level, the fan speed will drop, so the indoor
CO2concentration may rise.
2) If PM2.5 concentration control is disabled and the CO2concentration is maintained at a low level, the fan speed will drop, so the indoor
PM2.5 concentration may rise.
* Refer to section 6 for details on the concentration control in a group connection system.
6 Remote controller display and concentration control according to system
configuration
●
Heat recovery ventilation unit only system
(when multiple heat recovery ventilation units are connected in a group)
The CO2/ PM2.5 concentration displayed on the remote controller (RBC-A*SU5*) is the concentration detected by the sensor connected to
the header unit.
Automatic fan speed control by sensor is only applicable to heat recovery ventilation units connected to a sensor.
Heat recovery ventilation units not connected to sensors will run at a fixed ventilation fan speed setting when Fan speed [AUTO] is selected.
(Refer to section 8)
●When system is linked with air conditioners
The CO2/ PM2.5 concentration displayed on the remote controller (RBC-A*SU5*) is the concentration detected by the sensor connected to
the heat recovery ventilation unit with the smallest indoor address.
Automatic fan speed control by sensor is only applicable to heat recovery ventilation units connected to a sensor.
Heat recovery ventilation units not connected to sensors will run at a fixed ventilation fan speed setting when Fan speed [AUTO] is selected.
(Refer to section 8)
7 Minimum ventilation fan speed setting
When running under automatic fan speed control, the minimum ventilation fan speed is set as [Low] but this can be changed to [Medium]. (In
this case, the fan speed is controlled at 5 levels)
DN code SET DATA 0000 0001
79B Concentration-controlled minimum ventilation

(factory default) Medium
8 Fixed fan speed setting with no sensor equipped when there is a sensor failure
In the system configuration in section 6 above, heat recovery ventilation units with no sensor equipped will run at a fixed ventilation fan
speed setting when Fan speed [AUTO] is selected with the remote controller. In addition, for heat recovery ventilation units equipped with a
sensor, the unit will also run at a fixed ventilation fan speed setting when the sensor performing concentration control fails (*1).
This fixed ventilation fan speed setting can be set.
DN code SET DATA 0000 0001 0002
79A Fixed ventilation fan speed setting High
(factory default) Medium Low
When this DN code is set to [High], the unit will run in the [High] mode even if the DN code “5D” is set to [Extra High].
If the fan speed needs to be set to [Extra High], see the installation manual of the heat recovery ventilation unit (5. Power setting for applied
control) and set the DN code “750” and “754’ to 100%.
*1 If both CO2and PM2.5 concentration control are enabled and either sensor fails, the unit will run at automatic fan speed control with the
functioning sensor.
9 CO2sensor calibration function settings
The CO2sensor uses the lowest CO2concentration in the past 1 week as a reference value (equivalent to the general atmospheric CO2
concentration) to perform automatic calibration. When the unit is used in a location where the atmospheric CO2concentration is always
higher than the general reference value (along main roads etc.), or in an environment where the indoor CO2concentration is always higher,
the detected concentration may deviate greatly from the actual concentration due to the autocalibration effect, so either disable the
automatic calibration function, or perform force calibration where necessary.

concentration
For force calibration, after setting the DN code “564” to 0002, set DN code “565” to a numeric value.
To perform force calibration, a measuring instrument that can measure the CO2concentration is required separately. Run the heat recovery
ventilation unit at a time period during which the CO2concentration is stable, and quickly set the CO2concentration value measured at the
air inlet (RA) with the remote controller using the prescribed method.
Force calibration is performed once only after configuration ends. Not implemented periodically.
10 CO2sensor altitude correction
Correction of the CO2concentration will be performed according to the altitude at which the heat recovery ventilation unit is installed.
DN code SET DATA 0000 0000 - 0040
563 CO2sensor altitude correction No correction (altitude 0 m)
(factory default) Setting data × 100 m altitude correction
11 Ventilation fan speed [AUTO] fixed operation setting
For a system that is connected to an air conditioner, Fan speed [AUTO] cannot be selected from the remote controller. By changing the DN
code “796” setting, it is possible to run the heat recovery ventilation unit at Fan speed [AUTO] regardless of the fan speed set by the remote
controller.
In this case, take note that the fan speed will be fixed as [AUTO].
DN code SET DATA 0000 0001
