Principle of operation
SMO 10 is an advanced control module, which, together
with NIBE air/water heat pump and existing heating and
hot water equipment, creates a complete installation.
SMO 10 can be used for with several different connection
options. The base is the NIBE air/water heat pump, which,
in turn, can be docked on to electric boilers, oil-fired boil-
ers and accumulator tanks, for example, NIBE VPA.

of operating disturbances. Additional heat out-
put is limited depending on selected connec-
tion option. See section “Dealing with malfunc-
tions”. NOTE! There is a risk of freezing at
outdoor temperatures below 0°C.
Operating mode
This button is used to set the required operating
mode with regard to permitting/blocking the circula-
tion pump and additional energy. The change does
not need to be confirmed with the enter button.
The current operating mode is shown on the display
when the button is pressed and the mode changes
when you continue to press the button. The display
returns to the normal display mode once the enter
button is pressed.
The different operating modes are:
Auto mode: SMO 10 automatically selects the op-
erating mode with reference to the outdoor temper-
ature. The circulation pump and addition are permit-
ted to run as needed.
Summer mode: Only production of hot water with
the air/water heat pump. The circulation pump and
additional heat are blocked. However, when “Extra
hot water” is activated the immersion heater is con-
nected.
Spring/Autumn mode: Only production of heat
and hot water with the air/water heat pump. The
circulation pump is operational. Additional heat
blocked. However, when “Extra hot water” is acti-
vated the immersion heater is connected.
NOTE! In the event of an alarm from the air/water
heat pump, the different modes are not displayed.
Extra Hot Water*
The “Extra hot water” function is activated for a pe-
riod of 3 hours using this button. The change does
not need to be confirmed with the enter button.
At activation, the hot water temperature increases
above the normal temperature, up to the set value.
Also see section ”Function description” – ”Extra hot
water ”.

The basic heating is set using menu 2.1 and with the
“Heating curve offset” knob.
If you do not know the correct settings use the basic data
from the map opposite.
If the required room temperature is not obtained, readjust-
ment may be necessary.
NOTE! Wait one day between settings so that the tem-
peratures have time to stabilise.

Heating control system
The indoor temperature depends on several factors.
During the hot season, solar radiation and heat given off
by people and equipment are sufficient to keep the house
warm. When it gets colder outside, the heating system
must be started. The colder its gets, the hotter the radia-
tors must be.
This adjustment is made automatically, however the basic
settings must first be made on the boiler, see the section
“Default setting”.
Room temperature
Readjustment the default settings
Cold weather conditions
When the room temperature is too low, the “Heat
curve” value is increased in menu 2.1 by one incre-
ment.
When the room temperature is too high, the “Heat
curve” value is lowered in menu 2.1 by one incre-
ment.
Warm weather conditions
If the room temperature is low, increase the heating
curve offset setting by one step.
If the room temperature is high, reduce the “Heating
curve offset” setting by one step.
Changing the room temperature manually
If you want to temporarily or permanently lower or raise
the indoor temperature relative to the previously set tem-
perature, turn the “Heating curve offset” knob anticlock-
wise or clockwise. One to three lines approximately repre-
sents a one degree change in room temperature.
NOTE! An increase in the room temperature may be in-
hibited by the radiator or floor heating thermostats, if so
these must be turned up.

Room temperature
“Heat curve” in menu 2.1 and
“Max supply temp.” in menu 2.4 are
adjusted according to the heating system
in question.
NOTE!
Setting with diagrams
The heating control system on the SMO 10 is controlled by
the outside temperature. This means the flow temperature
is regulated in relation to the current outdoor temperature.
The diagram is based on the dimensioned outdoor temper-
ature in the area and the dimensioned supply temperature
of the heating system. When these two values “meet”,
the heating control's curve slope can be read. This is set on
menu 2.1 “Heat curve”.
A suitable value is set using the knob on the front panel,
“Offset heat curve “. A suitable value for floor heating is
-1 and for radiator systems -2.

In cases where the additional heater is located after the
three way valve, the hot water is heated by the hot water
heater’s immersion heater when additional heat is acti-
vated.
Docking – Hot water heating

Connecting hot water heating
The three-way valve (VXV1) is connected to terminal 17
(230 V during hot water production), 18 (L1) and 19 (N)
on terminal block (11).
The hot water sensor (VVG) is installed in the hot water
accumulator tank’s submerged tube.
To measure the precise values the sensor must make good
contact with the measuring point. This sensor must be
connected to terminals 43 and 44 on the terminal block
(11).
The immersion heater in the hot water heater must be
used in cases where the additional heater is located after
the three-way valve. Connect to terminals 26 (230 V) and
27 (N) on terminal block (11).
If hot water circulation (VVC) is to be used, connect the
pump to terminals 28 (230 V) and 29 (N) on terminal block
(11).
See section “Electrical connection” – “Terminal diagram”
for complete terminal diagram.

SMO 10 controls air/water heat pump, oil-fired boiler,
circulation pumps, shunts, etc. The air/water heat pump
works with floating condensing against the heating system
and prioritises hot water charging via the reversing valve
(VXV1). The heat pump works in stage 1 or stage 2 de-
pending on the outdoor air temperature.
The oil boiler starts when the number of degree minutes
is reached. If the temperature at the boiler sensor (PG)
reaches the set start level the shunt valve starts to regulate
according to set period and impulse times. If the tempera-
ture in the boiler drops below the preset temperature, the
shunt valve closes.
If the heat pump cannot meet the heating requirement,
the oil-fired boiler is started and additional heat is shunted
in.
In combined mode, the three-way valve (VXV1) is open
towards the heating system.
NOTE!
To prevent interference, sensor cables and communication
cables must be separated (min 20 cm) from high voltage
cable when cable routing.

Docking – Immersion heater after three way valve
NIBE air/water heat pump docked to the immersion heater after the three way valve together with SMO 10 and
water heater (floating condensing)
Function
SMO 10 controls air/water heat pump, immersion heater,
circulation pumps, three way valves, etc. The air/water
heat pump works with floating condensing against the
heating system and prioritises hot water charging via the
reversing valve (VXV1). The air/water heat pump works in
stage 1 or stage 2 depending on the outdoor air tempera-
ture and the heating requirement.
If the air/water heat pump does not manage the heat-
ing demand, additional heat from the immersion heater is
engaged.
When additional heat is engaged, hot water is heated us-
ing the immersion heater in the hot water heater.
In combined mode, the three way (VXV1) is open towards
the heating system.
NOTE!
To prevent interference, sensor cables and communication
cables must be separated (min 20 cm) from high voltage
cable when cable routing.
