Communication functions
The holding registers are transmitted in 16 bit.
Read and write weekly programme of switching commands via Modbus
The holding registers from 42000 contain the switching commands for heating
circuit 1. The following allocation applies:
Command1 Command2 Command3 Command4 Command5 Command6
Mon 42000 42001 42002 42003 42004 42005
Tue 42006 42007 42008 42009 42010 42011

Switching commands Tab.7
For the other control loops or the program for the pilot timer/circulation pump, the
same logic applies, but the register numbers are 100 higher in each case.
Every possible switching command has its own holding register (a 16-bit value)
that can be read or written. For the contents of the register, the following applies:
Command Time
Numeri-
cal value
(decimal)
3 0 7 3 0 30730
1 = Back-up mode
2 = Reduced mode
3 = Normal mode
To change the factory setting for the fi rst switching command (nominal mode,
every day from 6:00 hrs) to 7:30 hrs, you have to write a value of 30730 (instead
of the current 30600) in register 42042.
Read and write calendar programme of switching commands via Modbus
The 20 holding registers from 42500 to 42519 contain the 20 possible switching
commands for the calendar switching programme. For the contents of the
register, the following applies:
Command Date
Numeri-
cal value
(decimal)
1 3 1 1 2 13112
1 = Back-up mode
2 = Reduced mode
3 = Normal mode
