1.1 GENERAL INFORMATION
The Direct Digital Controller is a device that is applicable as a
panel, and which is able to show, on a backlit graphical LCD
display of 128x64 pixels, all the status, operating and error
conditions of each individual unit to which it is linked. The DDC
(Direct Digital Controller) controls water thermostating by
controlling the switch-on and switch-off of the units connected to it.
The Digital Panel can support and manage up to 32 modules (16
for heating and 16 for cooling) where module refers to the ability of
a machine to produce cooled or hot water;
therefore the ACF 60-
00 comprises a module for the production of chilled water, and the
AY 00-120 and GAHP-A each comprise a module for the
production of hot water; on the other hand, the GAHP-AR and the
GAHP-GS/WS comprise two modules, one for the production of
chilled water, the other for hot water (see table below).
The Direct Digital Controller, on the other hand, is able to manage
a single prontoclima heater/heater-chiller.
The Direct Digital Controller is, in addition, able to manage several
plant configurations for the production of hot and/or chilled water,
in particular:
1. 1 plant for the production of chilled water (
cold plant ). For example it is possible to connect up to a
maximum of 16 ACF 60-00 which correspond to a maximum of 16 chilling modules; OR:
2. 1 plant for the production of hot water ( hot plant ). For example it is possible to connect up to a maximum
of 16 GAHP-A or ACF 00-120 which correspond to a maximum of 16 heating modules; OR:
3. 2 independent plants, one to product chilled water, the other to produce hot water (4-line configuration)
able to run simultaneously ( one cold plant and one hot plant, independent ). It is therefore possible to
manage both plants described in points 1 and 2, for a maximum of 16 modules for heating; for example,
this is useful for installations with AHU fitted with a post-heating exchanger which works at the same time
as the cooling OR:
4. 1 plant for alternate production (summer/winter) of hot or chilled water ( 2-line hot-cold plant ). This is a
two-line plant that, for example, in the winter serves the heating network and in the summer serves the
cooling network. For example it is possible to connect up to a maximum of 16 GAHP-AR or AYF 60-119/2
which correspond to a maximum of 16 heating modules for chilling and 16 modules for heating.
To create high output plants it is also possible to connect two or three DDCs together in order to control up to
64 or 96 modules (up to 32 units may be linked to each DDC).
