2.2 Expansion modules
2.2.1 Heating circuit module
Two heating circuits can be controlled as standard with the core module.
To add further heating circuits, the heating circuit module boards must be expanded. Expansion can include up
to eight heating circuit modules (addresses 0 to 7). A total of up to 18 heating circuits can be controlled. It is
important to ensure that the module address is set correctly.
