6.4 Possible system layouts
The controller is characterised by such flexibility that units may be combined with different systems, ranging from easy
systems with one single temperature zone to more complex systems with two temperature zones and domestic hot water
production.
Appendix E to this manual lists some possible system layouts.
Layouts are given as examples only. The system must be sized correctly and implemented in accordance
with the standards existing in the country where the unit is installed and following the best practices.
The recommended system layout diagram is attached for each layout. Some base controller parameters then need to be set
up, consistently with the system layout and the electrical connections. Please find the relevant information in the controller
Service Manual.
The flow chart below is useful to identify the type of system that best suits your requirements.

Units featuring an advanced controller (V6) are designed to control all the recommended system layouts. On
the other hand, units featuring a base controller (V5+) are only designed to control recommended system
layouts with reference “E.1” and “E.6”.
