Configuring the solar control module

The solar control module is recognised as a KM BUS
subscriber automatically by the heat generator control
unit (coding address 54).
The relevant codes for the solar control module are set
at the heat generator control unit.
Vitotronic control units for oil and gas boilers
Weather-compensated control:
■
Select group "Solar".
■ Constant temperature control:
Select group "4".
Vitotronic control units for heat pumps (type
WO1C)
■ Select parameter group "Solar".
■ In the "Type solar control unit 7A00" parameter,
select value 3.
■ Invoke parameter "C0xx".
For the final two characters (xx), enter the desired
coding address from the following table.
