The buttons
When you want to change a setting, the upper and the lower
buttons will give you a higher or lower value depending on the
button you are pushing. But before you change the value, you
must have access to the menu. You obtain this by pushing the
upper button for a couple of seconds - you will then enter the col-
umn with parameter codes. Find the parameter code you want to
change and push the middle buttons until value for the parameter
is shown. When you have changed the value, save the new value
by once more pushing the middle button.

Get a good start
With the following procedure you can start regulation very quick-
ly:
1 Open parameter r12 and stop the regulation (in a new and not
previously set unit, r12 will already be set to 0 which means
stopped regulation.)
2 Select electric connection based on the drawings on page 6
3 Open parameter o61 and set the electric connection number in
it
4 Now select one of the preset settings from the table on page 22.
5 Open parameter o62 and set the number for the array of preset-
tings. The few selected settings will now be transferred to the
menu.
6 Open parameter r12 and start the regulation
7 Go through the survey of factory settings. The values in the grey
cells are changed according to your choice of settings. Make any
necessary changes in the respective parameters.

gateway/system unit with setting o04.
