Parameter menu
It is possible to set different parameter values in a parameter menu. The parameter menu is
accessed by simultaneously holding the INCREASE and DECREASE buttons depressed for
about 5 seconds and then pressing the INCREASE button twice. The Service indication will
be displayed.
The display will initially show the parameter number “1”. Use the INCREASE and
DECREASE buttons to scroll between parameters.
Press the Occupancy button to select the desired parameter. The parameter number will be
replaced by the parameter value. The value can be changed using the INCREASE and
DECREASE buttons. If a button is held depressed the value will start scrolling, first slowly
and then with increasing speed in 3 – 4 steps with 2 – 3 seconds between steps.
Acknowledge/Regret To acknowledge and store a set parameter value, press the Occupancy button again, the
display then returns to showing the parameter number. To retrieve the original value, i.e. the
value before change, press the INCREASE and DECREASE buttons at the same time. The
original value is shown on the display.
Return After a certain time, about 1 minute, or when the INCREASE and DECREASE buttons are
pressed at the same time while in the menu, the display returns to the normal view. Exit is
shown on the display after the last parameter. The parameter menu is exited by pressing the
Occupancy button while in Exit. Pressing on INCREASE goes to the first parameter and
pressing on DECREASE goes to the last parameter.
