Configuration diagrams

Use of the configuration diagrams is explained in subsection 3.3.5 "Use of configuration
diagrams".

15.1.1 Terminal markings

The designations of the signal inputs and outputs and of the assigned connection ter-
minals are structured according to the following pattern:
Example Explanation
N.X3 N = controller RMK770
X3 = universal input
N.D1 N = controller RMK770
D1 = digital input
A9(2).Y1 A9 = type of extension module
(2) = 2nd extension module of the same type
Y1 = analog output DC 0...10 V
N.Q7 N = controller RMK770
Q7 = relay output

15.1.2 Code letters

Physical inputs and outputs are marked with capital letters:
Code letter Explanation
N Boiler sequence controller RMK770
A5 Universal module RMZ785
A7 Universal module RMZ787
A7 Universal module RMZ788
A9 Universal module RMZ789
D Digital input
X Universal input
Q... Switching load (changeover or N.O. contact)
Y Analog output DC 0...10 V
3P 3-position output in pairs
Internal signals are marked with small code letters:

x Analog or digital
a Analog
d Digital

15.1.3 Configuration choices

The maximum configuration is 3 extension modules, 7 single or twin pumps and
7 modulating outputs. The procedure for the configuration is always:
• from the arrow
to the line
• from capital letter to capital letter
• from small letter to small letter
