Key technical features

The RVD230 offers 2 key technical features:
• The controller has 28 different plant types preprogrammed.
Subsection 3.1.2 shows the relevant plant diagrams.
• The settings are assigned to different setting levels each of which contains a number
of function blocks with the relevant settings
3.1.1

Locking functions
For each function block, the required settings are available in the form of operating
lines. On the following pages, a description of the individual functions per block and line
is given.
3.1.2

Plant types

The RVD230 has 28 plant types preprogrammed, whereby the functions required for
each type of plant are ready assigned. When commissioning the installation, the rele-
vant plant type must be selected.
Each plant type is comprised of a heating circuit and a d.h.w. circuit. When making use
of all possible or practical combinations, the above mentioned total of 28 plant types
are available.
With the number of preprogrammed plant types available, practically all types of heat-
ing plants with district heat connection and own d.h.w. heating can be handled and
controlled.
Note on the plant diagrams: Elements shown in broken lines (sensors B7 and B71,
circulating pump and flow switch) are optional components.
