Lossnay In Duct CO₂ Sensor

Mitsubishi Lossnay PZ-70CSD-E2 – Duct-Mounted CO₂ Sensor

Product Overview

The Mitsubishi Electric PZ-70CSD-E2 is a duct-mounted CO₂ sensor designed to automatically adjust ventilation airflow based on indoor carbon dioxide levels.

Installed within the ventilation ductwork, the sensor continuously monitors CO₂ levels and communicates directly with compatible Mitsubishi Lossnay energy recovery ventilation systems, increasing airflow when additional fresh air is required and reducing airflow when demand is lower.

This demand-controlled ventilation helps maintain good indoor air quality while minimising unnecessary energy consumption.

Additional Information

Automatic CO₂-based airflow adjustment requires Auto Fan Mode to be enabled on the Lossnay system.

CO₂ control limits can be configured using the optional Mitsubishi Electric PZ-62DR-E Lossnay controller.

Unlike the wall-mounted PZ-70CSW-E2, this duct-mounted version does not feature a traffic light CO₂ indicator.
