Maintenance level
A number of execution options are available from the MAINTENANCE MENU (see
Table IV). This level is accessed only from the display mode in the
set points of CO
and CO
2
selection. A two buttons push
and an access
code restricts access,
intended for competent trained service personnel only. The Entr(+-)command is done
by PUSHING MENU AND ESC AT THE SAME TIME (hold down for about 10
seconds). The access code has eight binary digits; one press at MENU(+) equals 1
and one press at ESC(-) equals 0. The code value can be changed for your personal
choice from the software UIP 4.0.
Always use the ESC button to return to the DEFAULT mode. Several pushes of the
ESC button may be needed to return to the DEFAULT mode. The
Entr(+-)
push
(MENU & ESC) eventually leads to execution of functions, which causes temporary
or permanently change of any parameter, that affects the system outputs!
