tSENSE VAV is an advanced and versatile three-in-one controller designed for installation in the air-conditioned zone. The unit measures CO2 concentration, temperature and humidity in the ambient air accurately without need for additional compensation ─ true read. The data transmits to a BMS system using industry standard output signals and communication protocols. It is flexible in design with display, temperature control and combination of humidity control optional. Complies with ASHRAE standard 189.1 (±50ppm @ 1000ppm of measured CO2 value)
