General

The IAO-sensor product SSENSE Slim (sensor in industrial housing) is used to measure indoor air carbon dioxide concentration. The 300 mm long cable connected to the PCB makes it possible to place the sensor where the mounting is difficult.
The unit is designed for connecting to Direct Digital Control (DDC) with 0-5V signal inputs.
The eSENSE Slim has a permanently connected cable to the PCB.

Self-diagnostics

The system contains complete self-diagnostic procedures. A full system test is executed automatically every time the power is turned on. In addition, constantly during operation, the sensor probe is checked against failure.

NOTE!

The sensor accuracy is defined at continuous operation (at least 3 weeks after installation)
