2.8 Preliminary hardware list
The table below shows a preliminary hardware list. It provides the following information
for the various applications, and can therefore be used for a preliminary estimate when
preparing a quotation.
• Possible number of RXC controllers per NIDES
• Number of VISONIK points in the BPS
Application Number of DESIGO RX
controllers
per NIDES
VISONIK VISONIK
Template 1 Template 2
Approx. number of
VISONIK points

Radiator-type systems 80 47 … 50 140 … 240
Radiator / chilled ceilings 80 47 … 50 135 … 240
Fan-coil units 80 42 … 47 120 … 240
Integrated application
(HVAC, blinds, lighting)
42 … 60 30 … 39 220 … 420
VAV 80 42 ... 50 120 ... 240
Note the following in relation to the information in the table:
– Where the number of RXC controllers is given as a range, this is because individual
applications in the category concerned have a different number of network variables
(as for example in VISONIK Template 2 for applications RAD01 and RAD03 in the
“Radiators” category).
– The estimate of the number of controllers per NIDES is based on a maximum of 900
RS data points in the NIDES. However, it is advisable to plan a reserve capacity of
10% . (in other words, to use no more than 800 data points, if possible) to
accommodate future changes and enhancements etc.
– The term “VISONIK points” refers to TEC points and link points. These must not
exceed 500 in number.
For a guide to detailed calculation refer to Section 4, "Engineering".
This will help you determine more precise quantities, taking the following into account:
– Different applications (mixed)
– Additional RS master functions to be integrated from the extended selection.
