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 building energy management system. 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.
