Docking alternatives
SMO 40 can be connected with other products from
NIBE in several different ways, some of which are shown
below (accessories may be required).
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the accessories used. See page 55 for a list of the accessories
that can be used with SMO 40.
Installations with SMO 40 can produce heating and
hot water.
On cold days of the year when the access to energy
from the air is reduced the additional heating can
compensate and help to produce heat. The additional
heating is also good to have as assistance if the heat
pump ends up outside its working range or if it has
been blocked for any reason.
NOTE
The heating medium side and the hot water
side must be fitted with the necessary safety
equipment in accordance with the applicable
regulations.
This is the outline diagram. Actual installations
must be planned according to applicable
standards.

This installation alternative is suitable for simpler installations with a focus on low installation costs.
SMO 40 (AA25) starts and stops the heat pump (EB101)
to meet the heat and hot water demand of the installation. At simultaneous heating and hot water demand
the reversing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accumulator tank (CP10). When the hot water heater/accumulator tank is fully charged (CP10), the reversing
valve switches (AA25-QN10) to the climate system.
Additional heat (EB1) is connected automatically when
the energy demand exceeds the heat pump capacity.
This is used for both heating and charging hot water.
The additional heat can also be used if a higher temperature in the hot water is required than the heat pump
can produce.

NOTE
NIBE does not supply all components in this
outline diagram.
NOTE
Different types of demand (heating, hot water
etc.) mean different supply and return temperatures as well as different flows to the heat
pump.
When connecting pipes in installations with
several compressors and different heating
demands, ensure that these are separated so
that different return temperatures are not
mixed. Otherwise this can affect the heating
installation's efficiency.
At simultaneous heating and hot water demand the
reversing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accumulator tank (CP10). When the hot water heater/accumulator tank is fully charged (CP10), the reversing
valve switches (AA25-QN10) to the climate systems.
When the pool needs heating the reversing valve (CL11QN19) or (CL12-QN19) switches from the climate system to the pool system.
Additional heat (EB1) is connected automatically when
the energy demand exceeds the heat pump capacity.
Immersion heater (EB20) in the water heater/accumulator tank (CP10) is used to produce hot water if the
heat pump (EB101) is used for heating.
The additional heat can also be used if a higher temperature in the hot water is required than the heat pump
can produce.
See outline diagram for example.
This installations alternative is suitable for more complex installations with a focus on comfort.
SMO 40 (AA25) starts and stops the heat pumps EB101)
and (EB102) to meet the heat and hot water demand
of the installation. The heat pumps (EB103) and (EB104)
are used for heating and pool heating (one heat pump
for each pool).

Room sensor
Optional connections
Load monitor
When many power consumers are connected in the
property at the same time as the electric addition is
operating, there is a risk of the property's main fuse
tripping. The control module has an integrated load
monitor that controls the power steps for the electrical
addition by disconnecting step by step in event of
overload in a phase. Reconnection occurs when other
current consumption is reduced.
Connecting current sensors
A current sensor (BE1 - BE3) should be installed on each
incoming phase conductor in to the distribution box
to measure the current. The distribution box is an appropriate installation point.
Connect the current sensors to a multi-core cable in an
enclosure next to the distribution box. Use a multi-core
cable of at least 0.5 mm2 from the enclosure to the
heat pump.
Connect the cable to terminal X4:1 to 4 where X6:4 is
the common terminal block for the three current
sensors.
The size of the property’s main fuse is set in menu
5.1.12.
Install the sensor in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the sensor is not obstructed from
measuring the correct room temperature by being
located, for example, in a recess, between shelves, behind a curtain, above or close to a heat source, in a
draft from an external door or in direct sunlight. Closed
radiator thermostats can also cause problems.
The control module operates without the sensor, but
if one wishes to read off the accommodation's indoor
temperature in SMO 40 display the sensor must be installed. Connect the room sensor to terminal block X6:3
and X6:4 on the input card (AA3).
If the sensor is to be used to change the room temperature in °C and/or to change/stabilise the room temperature, the sensor must be activated in menu 1.9.4.
If the room sensor is used in a room with underfloor
heating, it should only have an indicatory function, not
control of the room temperature.

Step controlled additional heat
Shunt controlled additional heat
NOTE
NOTE
Mark up any junction boxes with warnings for
external voltage.
Mark up any junction boxes with warnings for
external voltage.
External step controlled additional heat can be controlled by up to three potential free relays in the control
module (3 step linear or 7 step binary). Alternatively
two relays (2 step linear or 3 step binary) can be used
for step controlled additional heat which means that
the third relay can be used to control the immersion
heater in the water heater/accumulator tank. With the
AXC 30 accessory a further three potential free relays
can be used for addition control, which then gives max
3 linear or 7 binary steps.
Step in occurs with at least 1 minute interval and step
outs with at least 3 seconds interval.
Step 1 is connected to terminal block X2:1 and 2 on
the additional relay card (AA7).
Step 2 is connected to terminal block X2:3 and 4 on
the additional relay card (AA7).
Step 3 or immersion heater in the water heater/accumulator tank is connected to terminal block X2:5 and
6 on the additional relay card (AA7).
The settings for step controlled additional heat are
made in menu 4.9.3 and menu 5.1.12.
All additional heat can be blocked by connecting a
potential free switch function to the software controlled input on terminal block X6 on the input card
(AA3) or terminal block X2 (see page 21) which is selected in menu 5.4.
This connection enables an external additional heater,
e.g. an oil boiler, gas boiler or district heating exchanger
to aid with heating.
SMO 40 controls a shunt valve and start signal to the
additional heating using three relays. If the installation
does not manage to keep the correct supply temperature, the addition starts. When the boiler temperature
has been increased to about 55 °C, the SMO 40 transmits a signal to the shunt (QN11) to open from the
addition. The shunt (QN11) adjusts so the true supply
temperature corresponds with the control system’s
theoretical calculated set point value. When the heating demand drops sufficiently so the additional heat
is no longer required the shunt (QN11) closes completely. Factory set run time for the boiler is 12 hours
(can be set in menu 5.1.12).
The settings for step controlled additional heat are
made in menu 4.9.3 and menu 5.1.12.
Connect the shunt motor (QN11) to terminal block
X2:4 (230 V, open) and 6 (230 V, close) on the additional relay card (AA7) and terminal block X1:0 (N).
Connect any additional heating on and off to terminal
block X2:2 on the additional relay card (AA7).
All additional heat can be blocked by connecting a
potential free switch function to the software controlled input on terminal block X6 on the input card
(AA3) or terminal block X2 (see page 21) which is selected in menu 5.4.

In the menu heating curve the presecribed heating
curve for your house can be viewed. The task of the
heating curve is to give an even indoor temperature,
regardless of the outdoor temperature, and thereby
energy efficient operation. It is from this heating curve
that the control module’s control computer determines
the temperature of the water to the heating system,
supply temperature, and therefore the indoor temperature. You can select heating curve and read off how
the supply temperature changes at different outdoor
temperatures here.

The slope of the heating curve indicates how many
degrees the supply temperature is to be increased/reduced when the outdoor temperature drops/increases.
A steeper slope means a higher supply temperature at
a certain outdoor temperature.
The optimum slope depends on the climate conditions
in your location, if the house has radiators or under
floor heating and how well insulated the house is.
The heating curve is set when the heating installation
is installed, but may need adjusting later. Thereafter
the heating curve should not need further adjustment.
Caution
In the event of making fine adjustments for
the indoor temperature, the heat curve must
be offset up or down instead, this is done in

window.
Alarm
In the event of an alarm with a red status lamp a malfunction has occurred that the heat pump and/or
control module cannot remedy itself. In the display, by
turning the control knob and pressing the OK button,
you can see the type of alarm it is and reset it. You can
also choose to set the installation to aid mode.
info / action Here you can read what the alarm means
and receive tips on what you can do to correct the
problem that caused the alarm.
reset alarm In most cases it is enough to select "reset
alarm" to correct the problem that caused the alarm.
If a green light illuminates after selecting "reset alarm"
the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the
problem that caused the alarm remains. If the alarm
disappears and then returns, see the troubleshooting
section (page 53).
aid mode ”aid mode” is a type of emergency mode.
This means that the installation produces heat and/or
hot water despite there being some kind of problem.
This can mean that the heat pump's compressor is not
running. In this case any electrical addition produces
heat and/or hot water.
