    “We selected t-mac BMS due to its ability to connect to our network, ‘talk’ to our existing ac units and report back. We can now react to faults/failures prior to the store realising they have an issue. The capability to change settings without requiring a member of staff to do so is a great element of the system. We required an easy to use interface with potential for expansion which was a big draw of the BMS.”

    "By working with t-mac we were able to identify that our immediate solution was to scrutinise the use of in-store equipment to save energy and carbon. Using t-mac’s expert advice and assistance we were able to implement a control strategy and immediately benefited from the energy reduction. To date we’ve chalked up a substantial reduction in energy usage and carbon emissions across the 1,600 UK branches. We’re confident that the system will continue to be a winner, saving carbon and cost for years to come.."
