As cloud-ready or IoT controllers, our DEOS DDC controllers represent the central intelligence in your building. They are used for holistic building and room automation, are specialized for HVAC applications and can be freely programmed. The main task of the automation stations is to control, regu...
"Typically, most buildings do not have the DDC system performing smoke control. It is more common for smoke control to be accomplished via the fire alarm system." Segall explained that the project goal was to satisfy the need to develop a control system that could monitor and control HVAC, ...
Significant savings can be realized by implementing a night HVAC management program during the unoccupied time when the temperature in the facility is set below or above the normal comfort temperature for the heating and cooling months respectively. Conventional means of achieving this often proved to...
As direct digital control (DDC) started in the ventilation, and air conditioning (HVAC) industry, manufacturers each developed their own unique, proprietary, application software to produce a DDC system for HVAC. These proprietary systems could not communicate with each other unless a “translator,”...
