BMS controller Microprocessor digital controller for building management is more flexible

STEC Control, Lda., Portugal, was established in 1990 developing, producing, marketing and installing electronic equipment for Building Management Systems. The company has 3 employees with one involved in electronic design.

Building management systems (BMS) are aimed at all big buildings or households which need to have a simple and reliable way to control and monitor all aspects of its management. The future trend is to bring BMS to all building that are constructed. STEC has a 10% market share of the total Portuguese market, which has an annual value of 2,2 MEUR.

The company has only one type of product for which it has been using third party controllers from a British company with very limited features. Although these controllers present a good performance, cost is high and programmability very difficult for the common user. Software tools provided by the third party are very low-level and require a string expertise in these matters from the user side.

The new product is also based in a microprocessor device having all the features presented by the third party plus a communication network with distributed control. Through the use of this network and a PC software application, a Control Centre will be capable of monitoring most important activities in building management with a simple procedure.

For the successful conclusion of this project independent consultants were used. This was important due to the small number of people that work at STEC Control.

While cost advantage is achieved with a much more competitive controller, simplicity and flexibility is also added, withdrawing much of the usual engineering overhead during installation. The increment of these capabilities at STEC Control cost 40000 EUR and took 9 months. FUSE investment will be returned in a little over one year, with a ROI of 428%.

The experiment is of interest for companies that are entering into microelectronics and need to use a generic programmable logic controller with open architecture.
