The Trane BAYSENS251A Wall Mount Sensor is a condition monitoring element used to measure the concentration of carbon dioxide in the interior of HVAC systems. It is applied to the walls of commercial and institutional buildings, where it senses the levels and transmits the data to the building automation and HVAC systems to aid in controlling the ventilation and ensuring indoor air. This clock gives readings that will assist in adjusting airflow according to occupancy and air requirements. It is connected to controls to optimise, energy consumption and meet the ventilation standards.
