For the Installer
Hold the Channel button down for about 7 seconds to
access the following menus.
Then press Channel again until you reach the desired
display mode. To change the value of a displayed vari-
able, first press the Increase button once. A cursor will
appear under the value. The value can now be
changed by pressing the Increase or Reduce buttons.
Pressing the Channel button again moves the cursor
to the value below, which in some cases can now be
changed.
Control of the electrical output for best comfort is man-
aged by the computer. It calculates the flow tempera-
ture deficit in the form of degree-minutes.
If, for example, the flow temperature has been 3
degrees lower than the calculated flow temperature for
60 minutes; 3 x 60 = 180 degree minutes is registered
by the computer. Using the standard setting the num-
ber of degree minutes should amount to 360 (60 +
300) before the immersion heater’s first step is con-
nected. After which the following steps are connected
with a further 100 degree minutes difference. The out-
put step remains actuated until the degree minute
deficit for each step has been compensated, which
means that the flow temperature must be as many
degree minutes above the calculated flow level as it
was previously under. This is how the
average flow temperature calculated by the computer
is obtained.
General
Settings
GM
[P]
Current value for number of degree-minutes.
The value can be changed in order to hasten the
start of heat production.
Setting range: -3050 – +100.
WW diff HP
[P]
The greatest temperature variation from the
nominal value for the heat medium (WW) before
positive operation of the heat pump takes place.
Basic setting: 13.
Setting range: 3 – 25.
Diff HP-Add
[P]
Variation downwards from WW diff HP at
which the value positive operation of additional
heat (Add) takes place.
Basic setting: 3.
Setting range: 1 – 8.

This menu is a submenu to menu 9 and is activated by
using the Increase button, set the cursor under the
value for GM and press the Channel button.
The first stage of additional heat (if used) is not
switched on until the sum of the HP-°in and Add-°in
set in this menu is reached. Any other steps are con-
nected between 360 degree minutes and 560 degree
minutes at even intervals.
HP-°min
[P]
Degree minute deficit before the heat pump
can start.
Basic setting: 60.
Setting range: 5 – 250.
Add-°min
[P]
Additional degree-minute deficit before the
first stage of additional heat (TS) is allowed to be
switched on.
Basic setting: 300.
Setting range: 50 – 2500.
HP-int
[P]
Min interval in minutes between when the
heat pump starts.
Basic setting: 20.
Setting range: 20 – 60.
HWT-stop
[P]
Stop temperature for water heater charging
when operating with additional heat only.
Basic setting: 50.
Setting range: 10 – 70.
