functions
Setting range: compressor, addition, heating, cooling
The heat pump operating mode is usually set to "auto".
It is also possible to set the heat pump to "add. heat
only", but only when an addition is used, or "manual"
and select yourself what functions are to be permitted.
Change the operating mode by marking the desired mode
and pressing the OK button. When an operating mode
is selected it shows what in the heat pump is permitted
(crossed out = not permitted) and selectable alternatives
to the right. To select selectable functions that are permit-
ted or not you mark the function using the control knob
and press the OK button.
Operating mode auto
In this operating mode you cannot select which functions
are to be permitted because it is handled automatically
by the heat pump.
Operating mode manual
In this operating mode you can select what functions are
permitted. You cannot deselect "compressor" in manual
mode.
Operating mode add. heat only
Caution
If you choose mode "add. heat only" the com-
pressor is deselected and there is a higher oper-
ating cost.
In this operating mode the compressor is not active and
only additional heating is used.

Functions
"compressor" is that which produces heating and hot
water for the accommodation. If "compressor" is
deselected, a symbol in the main menu on the heat pump
symbol is displayed. You cannot deselect "compressor"
in manual mode.
"addition" is what helps the compressor to heat the
accommodation and/or the hot water when it cannot
manage the whole requirement alone.
"heating" means that you get heat in the accommoda-
tion. You can deselect the function when you do not
wish to have heating running.
"cooling" means that you get cooling in the accommod-
ation in hot weather. You can deselect the function when
you do not wish to have the cooling running. This altern-
ative requires an accessory for cooling or if the heat pump
has a built in function for cooling.
Caution
If you deselect "addition" it may mean that
sufficient heating in the accommodation is not
achieved.
28 Dealing with alarms
Select how you want the heat pump to alert you that
there is an alarm in the display here.
The different alternatives are that the heat pump stops
producing hot water (default setting) and/or reduces the
room temperature.
Caution
If no alarm action is selected, it can result in
higher energy consumption in the event of an
alarm.
