The Setting

Thayer Corp., is a friend and partner of the town of Newmarket, New Hampshire, providing mechanical systems support and service to the community for several years. Last year, several municipal buildings within the town were outfitted with a new Siemens system, a large investment for the town but with high hopes that these systems would deliver quality environments for the staff in all six buildings.

Unfortunately, as is the case with complex mechanical systems, there were seemingly unfixable challenges that plagued many of the units, leaving facilities managers and staff frustrated and worried about the ability to maintain comfortable environments over the next several months. The Thayer Team, along with members of their new partnership group Computrols, assessed the situation and determined adjustments needed to be made to the controls in order to get back on track.

Proposed Solution

Thayer Corp. came in and offered a BACnet interface via Computrols Building Automation System. We presented our solution and demonstrated Computrols Building Automation Software (CBAS). The town’s facilities staff was instantly intrigued by this opportunity. Thayer Corp. would leverage all of the town’s existing Siemens field hardware by adding an 8-LX controller at each site and replacing Siemens Desigo software with a CBAS front-end.


This approach successfully enabled the customer to leverage their existing investment while getting a quality product and service. Thayer will continue with their three-year maintenance agreement with the town, including system support and upkeep, and is now in a position to assist with the facilities within the school system.
