CMF10
Configuration
All configuration menus lie in the 10-seconds level. This
level is accessed from the Base Display by pressing and
holding the encoder button for 10 seconds.
There are numerous configuration menus covering all
available options and combinations.
In some cases, making a certain choice in one menu will
mean that you will only see certain other menus. For
example, the menu for setting the damper minimum limit
is only shown if you have configured AO2 to be a damper
control output.
