Configuration diagrams

The use of the configuration diagrams is explained in subsection 3.2.4.

16.1.1 Terminal markings

The designations of the signal inputs and outputs and of the assigned connection
terminals are structured as follows:
Example Explanation
N.X3 N = controller RMH760B
X3 = universal input
A9(2).Y1 A9 = type of extension module
(2) = 2nd extension module of same type
Y1 = analog output DC 0...10 V
N.Q5 N = controller RMH760B
Q5 = relay output

16.1.2 Code letters

Physical inputs and outputs are identified by uppercase code letters:
Code letter Explanation
N Heating controller RMH760B
Heating circuit module RMZ782B
A2
DHW module RMZ783B
A3
A7 Universal module RMZ787
A9 Universal module RMZ789
X Universal input
Q... Switching load (changeover or NO contact)
Y Analog output DC 0...10 V
3P 3-position output, pairs
Internal signals are identified by lowercase code letters:

x Analog or digital
a Analog
d Digital
i Pulse

16.1.3 Configuration choices

Available are a maximum of 4 extension modules, 6 single or twin pumps, and 6 posi-
tioning outputs. Configuration is always made as follows:
• From arrow
to line
• From uppercase to uppercase letter
• From lowercase to lowercase letter

16.1.4 Examples

The following examples show the type of plant of each plant type group (H0, H0-x, H1-
x, H2-x, etc.) that contains all possible plant sections (heating circuits, etc.).
