6.3 Auto fan speed setting without Lossnay or M-NET centralized remote controller
If not connecting remote controllers or M-NET centralized controllers to the Lossnay unit, set the "Auto fan speed setting without Lossnay or M-NET
centralized remote controller" dip switch to ON.

The upper and lower limit of CO
The Lossnay unit controls its fan speed according to the set upper and the lower limit. Refer to the example on below.
Configure the settings from the remote controller CO
Instructions for the remote controller.
* Upper limit available setting range: 600 (lower limit + 300) to 2000 ppm (increments of 50 ppm)
* Lower limit available setting range: 300 to (upper limit - 300) ppm (increments of 50 ppm)
* This automatically controls the amount of airflow with the set CO
depending on the usage environment and product installation conditions, the value may exceed upper limit depending on the usage environment .
* If not using a remote controller, automatic airflow control will be carried out at the factory default setting.
* Factory default setting: Upper limit 1000 ppm, lower limit 450 ppm

The CO
sensor recognizes the lowest CO

concentrations), and carries out calibration. The standard value for calibration is 400 ppm, however if this product is used in locations in which the
concentration is normally higher than the standard value (such as near a major highway), or in an interior environment with higher-than-
outside CO

concentrations, then there may be a significant discrepancy between the actual CO

Therefore, configure the concentration correction function for CO

[LED operation overview]
The LED will light in accordance with the operations shown below. Settings thresholds and lighting times can be changed in the remote controller
function settings.
When the CO
exceeds the set threshold
value
(1) LED usage setting during non operation
It is possible to select lit or unlit during Lossnay unit is not operating.
The factory default setting is to turn on/turn off the LED display in accordance with Lossnay unit operation/shutdown.
For how to configure the setting, refer to "LED usage setting for PZ-70CSW-E during non operation" in the Installation Instructions for the Lossnay
unit.
(2) Threshold concentration
concentration at which the LED changes from "LOW (green)" to "MID (orange)" can be set within the range of 1000 to 2000 ppm.
