It's not unusual for a site to have a number of buildings each with a different heating/cooling system and each having a different type of control mechanism, ranging from a simple time clock to a BMS. HeatingSave is perfect for this type of site, as it allows the Facilities Manager to control and manage the energy usage from just one system.
We had an example were a HeatingSave system was installed for school with 5 heating systems. Before HeatingSave the site manager spent time going from building to building adjusting the heating. Now he does it all from his office.
