3 .6 .3 Installer parameters
The access to installer parameters is indicated by LED L12 on.
To access branches CFn, dFr, Fan, ALL, EXV follow the navigation diagram (see "3.7 Navigation diagram" on pege 18).
The route of each branch is cyclical: the first variable can be reached from the last one and vice versa by pressing
[DOWN] keys.
Inside each branch, by pressing and holding
the parameter to be changed has been detected:
− press
[SET] key to display its value
− press
[UP] or
[DOWN] keys to change its value
− press
[SET] key again to confirm the change and go back to the parameter display.
From any position inside the navigation diagram, press and hold
To go back from the parameter selection inside a branch to the selection of branches CFn, dFr, Fan, ALL, EXV press and hold [SET] key
until a beep is emitted, then release.
For the Installer branch parameters an access password is required (default parameter H18 = 000).
To exit, press and hold
[SET] key (about 10 seconds); otherwise the display mode is interrupted after a time t=60sec from the last
release of
