The REG System divides the management of the system into several subsystems, represented in this diagram to be kept in mind while programming the controller:
...
Dehumidifiers type subsystems deal with air dehumidification, with CMV system, and mainly with air-based heating/cooling integration system, such as fancoil.
Note
In fact, the name Dehumidifier assigned to this subsystem, is very limiting and it is a inheritance of the early versions of the REG System, when it “only” handled dehumidifiers; with the evolution of the REG System this subsystem has acquired many new functions and can be used to perform various tasks, but for simplicity and consistency it continues to be called “only” Dehumidifier.
...
The control of water pumps;
The determination of the temperatures set point (SET POINT AND SENSORS SETTINGS)
The control of the mixing valves (WATER PUMPS AND MIXING VALVES SETTINGS)
It is important to emphasize that the Circuits are not activated independently, but they are always activated by an upstream subsystem; specifically, circuits can be activated by a Zone, by a Dehumidifiers, or by DHW.
It is also possible to manage complex situation with distributions on several levels, where a circuit in turn actives other circuits (see FATHER CIRCUIT AND INTERLOCKED CIRCUIT).
Sources
Source-type subsystems manage the last link in the control chain, that is the production of the energy needed to heat, cool, and/or dehumidify the system.
