5-YEAR CALIBRATION GUARANTEE

Greystone offers a 5-year calibration guarantee on all its CD series wall and duct mount sensors used for CO2 based ventilation control when operated in an

environment that can utilize ASC software. If the sensor is found to be out of calibration more than 150 PPM as compared to a calibration gas or recently calibrated

reference, Greystone will provide a free factory calibration of the sensor if returned to Greystone. This guarantee only applies if the sensor is operated in an

environment where inside levels periodically drop to outside concentrations (i.e. during evenings or weekends when there is no occupancy) as is required by ASC

software.
