How to set each setting
Configure the settings when the heat recovery ventilation unit is stopped (Be sure to stop the heat recovery ventilation unit). Refer to the installation manual of the heat recovery ventilation unit ("7 Installation method for each system configuration") or the installation manual of the remote controller ("9. DN setting" in the "7 Field setting menu") for details on how to set the DN code.
1 Sensor connection settings (be sure to implement)
To perform automatic fan speed control using the CO2 / PM2.5 sensor, change the following setting (0001: 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 CO2 concentration and PM2.5 concentration. The CO2 target concentration and PM2.5 target concentration can be changed in the settings below.

* Although the fan speed is switched automatically using the set CO2 concentration 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 CO2 concentration 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 g/m3 or 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 CO2 concentration being 400 ppm, and the PM2.5 concentration being 5 g/m3.

* 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 CO2 concentration "- - ppm", PM2.5 concentration "- - g/m3" will also not be displayed.
* The display range of the concentration is as follows: CO2: 300 - 5000 ppm, PM2.5: 0 - 999 g/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 CO2 concentration 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.

5 Concentration control setting
Automatic fan speed control according to the CO2 concentration 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).

* Both CO2 concentration 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 CO2 concentration control is disabled and the PM2.5 concentration is maintained at a low level, the fan speed will drop, so the indoor CO2 concentration may rise.
2) If PM2.5 concentration control is disabled and the CO2 concentration 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)

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.

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 CO2 and PM2.5 concentration control are enabled and either sensor fails, the unit will run at automatic fan speed control with the functioning sensor.
9 CO2 sensor calibration function settings
The CO2 sensor uses the lowest CO2 concentration 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 CO2 concentration is always higher than the general reference value (along main roads etc.), or in an environment where the indoor CO2 concentration 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.

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 CO2 concentration is required separately. Run the heat recovery ventilation unit at a time period during which the CO2 concentration is stable, and quickly set the CO2 concentration 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.

Correction of the CO2 concentration will be performed according to the altitude at which the heat recovery ventilation unit is installed.

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].
