Controls - Toshiba MMS Series Design Manual

1-7. CONTROLS

Enabling a range of controls to meet various system needs
As the size of the building increases so does the number of air-condition-
ing units required. The multiple air-conditioning system MMS ensures
energy-saving and comfort by allowing a control of multiple units requiring
different loads.
The MMS provides a range of functions to enable an integrated, centralized
control of multiple units. Design an optimal system that best suits the
application and scale of your project.
