Circuit management subsystems (sometimes referred to as “manifolds”) allow you to control the pumps and, when required, the mixing valves of the systems. The system can manage up to 8 Circuits, which can be activated by:
...
Each circuit has both the Winter (Comfort or Economy or Antifreeze) and Summer (Comfort or Economy) Regulation, an offset that can be negative or positive and different for summer and winter, and a fixed Antifreeze Set only for winter:PHOTO TBD
...
In particular for summer and winter, it is possible to choose from the following options:PHOTO TBD
...
Direct Set Point: to be used if there is no outdoor probe or if you want to keep fixed the water outlet of a circuit.
Climatic curve: to be used if there is the outdoor probe, the reference outdoor temperatures are in winter -10°C, 0°C, 10°C, and 20°C; in summer they are 10°C, 20°C, 30°C, and 40°C.
KD: unlike the above climatic curve where at intermediate temperatures (5°C or 25°C) the outlet temperature is calculated by linear interpolation, KD uses characteristic curves as in the example graph below. Kd is the slope of the curve. If you have a radiant system, Kd will be low (between 0,2 and 0,8), while with radiators it can rise below 1:
...
It is possible to limit the outlet temperature between tMin and tMax and decide to which outdoor temperature (tOff) the system should switch off.
...
KDM: it is like KD, but tMin and tMax values are acquired from boilers of a specific manufacturer (do not use)
From Zone x: TBD
From Source x: TBD
From outlet probe: TBD
From inlet probe: to be used when installing the REG-010AD product (see REG-010AD manual)
From DHW Set Point: the set point used comes from the one set and actual in the DHW subsystem (see DHW SET POINT)
Warning
The set point may be changed if AMBIENT COMPENSATIONis used.
