The parameter menu
In the RU-units with display it is possible to set different parameter values in a parameter

twice. The Service indication will be displayed.
First the display will show the parameter-number 1. Scroll between parameters by using the
INCREASE and DECREASE buttons.
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
