H/C demand application examples

10.3.1 Overview
RMS705B as universal device can assume functions or partial functions of a
consumer, primary controller, or generation.
This results in sophisticated configurations and settings of the corresponding
distribution zones via the Communication menu.
The section explains the various applications and the required configuration and
communication settings to transmit H/C demand.
RMS705B can generate or evaluate demand signals for the following applications:
 Consumers (Section 10.3.3).
 Primary controllers (Section 10.3.4).
 Generation (Section 10.3.5).
 Consumers and primary controllers (Section 10.3.6).
 Consumers and generation (Section 10.3.7).
The following examples are for hot water networks (heat distribution zone).
However, they equally apply to chilled water networks (refrigeration distribution
zone).
10.3.2 Setting rules
Controllers (controllers 1...3, primary controller) on the H/C demand block are
enabled (shown as a cross in the configuration diagrams) if the controller's demand
is to be passed on.
Demand from controllers 1, 2 or 3 is to be passed on (to bus, to digital (d, Q) or
analog (a, Y) output).
Primary controller demand is to be passed on to the bus.
