Wall-mounting detector for carbon dioxide (CO2) with two relays for controlling devices to be activated in case of exceeding the preset thresholds. It is possible to choose the operating logic (direct or reverse) using the appropriate dip-switch. On the front there are two LEDs for indicating the status of the output relays and another three for indicating the air quality. In addition to the CO2 concentration, the instrument can also measure humidity and temperature. For this reason there are also three analogue outputs (CO2, humidity and temperature) that can be used to control any device that has a compatible analogue input.
