Users can change the room temperature but only by a pre-set band of 2oC on each occasion. Meanwhile, through the display panel, people are told exactly what is happening with the temperature, building occupation status and warm up periods in the local zone or any number of zones. Main plant only runs on demand from the appropriate zone controller. Because of its modularity, the system is versatile enough to control from 1 to 100 independent zones and 1 to 8 boilers in sequence. For engineers who require the power of the computer interface, the system allows remote communication, control and monitoring using a GUI through Doorway - the SeaChange PC based system supervisor.
Engineering is incredibly straightforward.
Having wired modules to the plant, it is literally a push button process to make them operate as an integrated system. No computers, programs or commissioning tools are needed. All the modules are connected on a two wire bus that carries both data and power. Modules are auto-configuring, automatically setting themselves up according to the plant connections made. For example, the boiler module will switch between flow and return temperature control depending on the sensors connected while the zone controller will automatically use a remote temperature sensor if one is fitted.
