Maico External CO2 Sensor for PP 45 Installation in Flush-Mount Box 45 CO2

The Maico External CO2 Sensor is a high-precision NDIR sensor designed for demand-controlled ventilation in conjunction with the Maico PP 45 ventilation unit. It measures CO2 concentration from 0 to 2000 ppm and provides a 0-10 V DC analog output for seamless integration. The sensor is installed in a standard flush-mount box (Unterputzdose) and is ideal for indoor air quality monitoring in residential and commercial spaces.

Advantages

Accurate CO2 measurement with automatic baseline calibration ensures long-term stability. The compact design allows discreet installation in a flush-mount box. Compatible with Maico PP 45 for energy-efficient ventilation control.
