Warranty – Trend Files

The contractor guarantees the specified points are trended and the "open" access to all trend data will continue to work as specified during the warranty period.

Warranty - New Equipment Controlled by the BAS

The equipment warranty period for new equipment controlled by the BAS will not begin until the trend files are completed and automatically transferred to the designated, folders or FTP sites.

Warranty - BAS Hardware and Software

Due to the challenges involved with determining the BAS hardware and software is working properly in Heating, Cooling and Shoulder seasons; the Customer has 6 months after the expiration of the warranty period to identify items that did not work correctly during the warranty period when it is demonstrated with trend data that the hardware or software provided did not work as intended.

There will be an adequate amount of trend data collected for all equipment in the Heating, Cooling, and Shoulder season temperature bins to verify the intended Occupied, Unoccupied and Standby sequences of operation in each season.   If there is not adequate data collected during the warranty period to verify equipment and control strategies are working as intended, the evaluation period will be extended as necessary.
