On larger projects Geomaster uses DDC (Direct Digital Controls) for ease of control and reporting whilst reducing running costs. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature.
A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air
to increase the amount of oxygen while also minimising heat/cooling losses. Geomaster can be integrated using industrial application layer protocols such as DeviceNet, SOAP, XML,BACnet, LonWorks and Modbus.
