User manual

For installation and service, the SERVICE menu is used, which is opened
by pressing the left button for five seconds. The SERVICE menu has a
number of sub menus, see Menu information.
The INFORMATION and SERVICE menus are intended for two categories
of user, customers and installers. Customers may only open the INFOR-
MATION menu with a limited number of settings. Installers have to be able
to change many settings in the control settings. The SERVICE menu is
therefore hidden from the customers.
