Monitoring device for safety shutdown of the boiler in case of carbon monoxide leakage.
Alarm threshold: 40 ppm / 1.0 seconds
This device is designed to protect people from the topical effects of carbon monoxide contact. Lifetime CO sensor max: approx. 6 years (max. 40°C, min. 40% rH), approx. 10 years (max. 28°C, 30% rH).
Important warnings:
The following substances can influence the CO detector and possibly trigger a false alarm. Therefore, they must not be used in the room where CO detector is installed: ethylene, ethanol, alcohol, iso-propanol, gasoline, toluene, ethyl acetate, hydrogen, hydrogen sulfide and sulfur dioxides.
Persons with specific medical conditions may not be adequately protected by the CO detector and should use a warning device that produces audible and/or visible signals even at carbon monoxide concentrations below 50ppm. If in doubt, consult a physician.
Performance features

Thank you very much! Contrary to the company Viessmann / customer service, they helped in a very short time to fix the error in my heating system and at a fair price. Simply super!!!!!!!!!!!!!!!
PRODOTTO ARRIVATO ABBASTANZA VELOCEMENTE
Device works fine and our heating is running again. Very competent and friendly service.
Original spare part that fit perfectly, after replacement problem-free start-up of the heater.
