The ULP is the sleek new member of the AirSense HVAC CO2 sensor family. Rising only about a quarter inch from the wall, it discreetly blends-into any architectural motif. But don’t be fooled by its slim profi le: inside is a powerhouse of modern sensor technology. The compact dual-beam detection system ensures accurate operation without the need for a “self calibration” algorithm and its attendant operational limitations. The ULP can be used with any building occupancy profile! The ULP mounts conveniently in a standard single-gang junction box.
The labeled and pluggable connector makes wiring quick and easy. All screw terminal connections can be made beforehand. And thanks to built-in circuit protection, the ULP will not be damaged even if it is mis-wired during installation. Just set the slider switch to select the desired output (0-5V, 0-10V, or 4-20mA) and plug-in the connector. There are no jumpers to lose or complicated documentation to decipher. LEDs are provided to indicate CO2 concentration levels (sometimes required for LEED certifi cation), but they can be disabled to make the ULP even more discreet when necessary.
