Docking alternativesSMO 40 can be connected with other products fromNIBE in several different ways, some of which are shownbelow (accessories may be required).

Further option information is available at www.nibe.euand in the respective assembly instructions for the ac-cessories used. See page 55 for a list of the accessoriesthat can be used with SMO 40.

Installations with SMO 40 can produce heating andhot water.

On cold days of the year when the access to energyfrom the air is reduced the additional heating cancompensate and help to produce heat. The additionalheating is also good to have as assistance if the heatpump ends up outside its working range or if it hasbeen blocked for any reason.

NOTE

The heating medium side and the hot waterside must be fitted with the necessary safetyequipment in accordance with the applicableregulations.

This is the outline diagram. Actual installationsmust be planned according to applicablestandards.

NOTE

NIBE does not supply all components in thisoutline diagram.

This installation alternative is suitable for simpler install-ations 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 install-ation. At simultaneous heating and hot water demandthe reversing valve switches (AA25-QN10) periodicallybetween the climate system and the water heater/ac-cumulator tank (CP10). When the hot water heater/ac-cumulator tank is fully charged (CP10), the reversingvalve switches (AA25-QN10) to the climate system.

Additional heat (EB1) is connected automatically whenthe 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 temper-ature in the hot water is required than the heat pumpcan produce.

NOTE


NOTE

Different types of demand (heating, hot wateretc.) mean different supply and return temper-atures as well as different flows to the heatpump.

When connecting pipes in installations withseveral compressors and different heatingdemands, ensure that these are separated sothat different return temperatures are notmixed. Otherwise this can affect the heatinginstallation's efficiency.

See outline diagram for example.

This installations alternative is suitable for more com-plex 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 demandof the installation. The heat pumps (EB103) and (EB104)are used for heating and pool heating (one heat pumpfor each pool).

At simultaneous heating and hot water demand thereversing valve switches (AA25-QN10) periodicallybetween the climate system and the water heater/ac-cumulator tank (CP10). When the hot water heater/ac-cumulator tank is fully charged (CP10), the reversingvalve switches (AA25-QN10) to the climate systems.When the pool needs heating the reversing valve (CL11-QN19) or (CL12-QN19) switches from the climate sys-tem to the pool system.

Additional heat (EB1) is connected automatically whenthe energy demand exceeds the heat pump capacity.Immersion heater (EB20) in the water heater/accumu-lator tank (CP10) is used to produce hot water if theheat pump (EB101) is used for heating.



GeneralDisconnect SMO 40 before insulation testing thehouse wiring.If the building is equipped with an earth-faultbreaker, SMO 40 should be equipped with a separateone.SMO 40 must be installed via an isolator switch witha minimum breaking gap of 3mm.For the electrical wiring diagram for the controlmodule, see page 59.Communication and sensor cables to external con-nections must not be laid close to high current cables.The minimum area of communication and sensorcables to external connections must be 0.5 mm² upto 50 m, for example EKKX or LiYY or equivalent.Use a screened three core cable for communicationwith the heat pump.When cable routing in SMO 40, cable grommets (UB1and UB2, marked in image) must be used.

NOTE

The switch (SF1) must not be moved to "" or" " until the boiler in the system has beenfilled with water. The compressor in the heatpump and any external addition can be dam-aged.

NOTE

Electrical installation and service must be car-ried out under the supervision of a qualifiedelectrician. Cut the current with the circuitbreaker before carrying out any servicing.Electrical installation and wiring must be car-ried out in accordance with the stipulations inforce.

When installing SMO 40, NIBE's air/water heatpump and any addition must be current free.

Optional connectionsLoad monitorWhen many power consumers are connected in theproperty at the same time as the electric addition isoperating, there is a risk of the property's main fusetripping. The control module has an integrated loadmonitor that controls the power steps for the electricaladdition by disconnecting step by step in event ofoverload in a phase. Reconnection occurs when othercurrent consumption is reduced.

Connecting current sensors

A current sensor (BE1 - BE3) should be installed on eachincoming phase conductor in to the distribution boxto measure the current. The distribution box is an ap-propriate installation point.

Connect the current sensors to a multi-core cable in anenclosure next to the distribution box. Use a multi-corecable of at least 0.5 mm2 from the enclosure to theheat pump.

Connect the cable to terminal X4:1 to 4 where X6:4 isthe common terminal block for the three currentsensors.

The size of the property’s main fuse is set in menu5.1.12.

Room sensorSMO 40 can be supplemented with a room sensor(BT50). The room temperature sensor has up to threefunctions:1. Show current room temperature in the control

module display.2. Option of changing the room temperature in °C.3. Makes it possible to change/stabilise the room

temperature.

Install the sensor in a neutral position where the settemperature is required. A suitable location is on a freeinner wall in a hall approx. 1.5 m above the floor. It isimportant that the sensor is not obstructed frommeasuring the correct room temperature by beinglocated, for example, in a recess, between shelves, be-hind a curtain, above or close to a heat source, in adraft from an external door or in direct sunlight. Closedradiator thermostats can also cause problems.

The control module operates without the sensor, butif one wishes to read off the accommodation's indoortemperature in SMO 40 display the sensor must be in-stalled. Connect the room sensor to terminal block X6:3and X6:4 on the input card (AA3).

If the sensor is to be used to change the room temper-ature in °C and/or to change/stabilise the room tem-perature, the sensor must be activated in menu 1.9.4.

If the room sensor is used in a room with underfloorheating, it should only have an indicatory function, notcontrol of the room temperature.

Step controlled additional heat

NOTE

Mark up any junction boxes with warnings forexternal voltage.

External step controlled additional heat can be con-trolled by up to three potential free relays in the controlmodule (3 step linear or 7 step binary). Alternativelytwo relays (2 step linear or 3 step binary) can be usedfor step controlled additional heat which means thatthe third relay can be used to control the immersionheater in the water heater/accumulator tank. With theAXC 30 accessory a further three potential free relayscan be used for addition control, which then gives max3 linear or 7 binary steps.

Step in occurs with at least 1 minute interval and stepouts with at least 3 seconds interval.

Step 1 is connected to terminal block X2:1 and 2 onthe additional relay card (AA7).

Step 2 is connected to terminal block X2:3 and 4 onthe additional relay card (AA7).

Step 3 or immersion heater in the water heater/accu-mulator tank is connected to terminal block X2:5 and6 on the additional relay card (AA7).

The settings for step controlled additional heat aremade in menu 4.9.3 and menu 5.1.12.

All additional heat can be blocked by connecting apotential free switch function to the software con-trolled input on terminal block X6 on the input card(AA3) or terminal block X2 (see page 21) which is selec-ted in menu 5.4.

Shunt controlled additional heat

NOTE


This connection enables an external additional heater,e.g. an oil boiler, gas boiler or district heating exchangerto aid with heating.

SMO 40 controls a shunt valve and start signal to theadditional heating using three relays. If the installationdoes not manage to keep the correct supply temperat-ure, the addition starts. When the boiler temperaturehas been increased to about 55 °C, the SMO 40 trans-mits a signal to the shunt (QN11) to open from theaddition. The shunt (QN11) adjusts so the true supplytemperature corresponds with the control system’stheoretical calculated set point value. When the heat-ing demand drops sufficiently so the additional heatis no longer required the shunt (QN11) closes com-pletely. 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 aremade in menu 4.9.3 and menu 5.1.12.

Connect the shunt motor (QN11) to terminal blockX2:4 (230 V, open) and 6 (230 V, close) on the addition-al relay card (AA7) and terminal block X1:0 (N).

Connect any additional heating on and off to terminalblock X2:2 on the additional relay card (AA7).

All additional heat can be blocked by connecting apotential free switch function to the software con-trolled input on terminal block X6 on the input card(AA3) or terminal block X2 (see page 21) which is selec-ted in menu 5.4.

Menu 1.3.1 - heatingIncreases or decreases in the accommodation temper-ature can be scheduled here for up to three time peri-ods per day. If a room sensor is installed and activatedthe desired room temperature (°C) is set during thetime period. Without an activated room sensor thedesired change is set (of setting in menu 1.1). One stepis usually enough to change the room temperature byone degree, but in some cases several steps may berequired.

Schedule: The schedule to be changed is selected here.

Activated: Scheduling for the selected period is activ-ated here. Set times are not affected at deactivation.

System: Which climate system the schedule is for isselected here. This alternative is only displayed if morethan one climate system is present.

Day: Select which day or days of the week the scheduleis to apply to here. To remove the scheduling for aparticular day, the time for that day must be reset bysetting the start time to the same as the stop time. Ifthe line "all" is used, all days in the period are set forthese times.

Time period: The start and stop time for the selectedday for scheduling are selected here.

Adjusting:How much the heating curve is to be offsetin relation to menu 1.1 during scheduling is set here.If the rooms sensor is installed the desired room tem-perature is set in °C.

Conflict: If two settings conflict with each other a redexclamation mark is displayed.

TIP

If you wish to set similar scheduling for everyday of the week start by filling in “all” and thenchanging the desired days.

TIP

Set the stop time earlier than the start time sothat the period extends beyond midnight.Scheduling then stops at the set stop time theday after.

Scheduling always starts on the date that thestart time is set for.

Caution

Changes of temperature in accommodationtake time. For example, short time periods incombination with underfloor heating will notgive a noticeable difference in room temperat-ure.

Menu 1.9 - advancedMenu advanced has orange text and is intended forthe advanced user. This menu has several sub-menus.

Menu 1.9.1 - heating curve

heating curve

Setting range: 0 - 15

Default value: 9

In the menu heating curve the presecribed heatingcurve for your house can be viewed. The task of theheating curve is to give an even indoor temperature,regardless of the outdoor temperature, and therebyenergy efficient operation. It is from this heating curvethat the control module’s control computer determinesthe temperature of the water to the heating system,supply temperature, and therefore the indoor temper-ature. You can select heating curve and read off howthe supply temperature changes at different outdoortemperatures here.

The slope of the heating curve indicates how manydegrees the supply temperature is to be increased/re-duced when the outdoor temperature drops/increases.A steeper slope means a higher supply temperature ata certain outdoor temperature.

The optimum slope depends on the climate conditionsin your location, if the house has radiators or underfloor heating and how well insulated the house is.

The heating curve is set when the heating installationis installed, but may need adjusting later. Thereafterthe heating curve should not need further adjustment.

Caution

In the event of making fine adjustments forthe indoor temperature, the heat curve mustbe offset up or down instead, this is done inmenu 1.1 temperature .

If it is warm outdoors and the room temperat-ure is too low, increase the curve offset by oneincrement.

If it is warm outdoors and the room temperat-ure is too high, lower the curve offset by oneincrement.

Menu 1.9.2 - external adjustment

climate system

Setting range: -10 to +10 or desired room temperat-ure if the room sensor is installed.

Default value: 0

Connecting an external contact, for example, a roomthermostat or a timer allows you to temporarily orperiodically raise or lower the room temperature. Whenthe contact is on, the heat curve offset is changed bythe number of steps selected in the menu. If a roomsensor is installed and activated the desired roomtemperature (°C) is set.

If there is more than one climate system the settingcan be made separately for each system.

Menu 1.9.3 - min. flow line temp.

climate system

Setting range: 5-70 °C

Default value: 20 °C

Set the minimum temperature on the supply temper-ature to the climate system. This means that SMO 40never calculates a temperature lower than that sethere.

If there is more than one climate system the settingcan be made separately for each system.

TIP

The value can be increased if you have, for ex-ample, a cellar that you always want to heat,even in summer.

You may also need to increase the value in"stop heating" menu 4.9.2 "auto mode set-ting".

Menu 1.9.4 - room sensor settings

factor system

Setting range: 0.0 - 6.0

Default value: 2.0

Room sensors to control the room temperature can beactivated here.

Here you can set a factor (a numerical value) that de-termines how much an over or sub normal temperature(the difference between the desired and actual roomtemperature) in the room is to affect the supply tem-perature to the climate system. A higher value gives agreater and faster change of the heating curve's setoffset.

NOTE

Too high a set value for "factor system" can(depending on your climate system) producean unstable room temperature.

If several climate systems are installed the above set-tings can be made for the relevant systems.

Menu 1.9.7 - own curve

Select a change in the heating curve at a certain out-door temperature here. One step is usually enough tochange the room temperature by one degree, but insome cases several steps may be required.


The heat curve is affected at ± 5 °C from set outdoortemp. point.

It is important that the correct heating curve is selectedso that the room temperature is experienced as even.

TIP

If it is cold in the house, at, for example -2 °C,"outdoor temp. point" is set to "-2" and"change in curve" is increased until the desiredroom temperature is maintained.

SMO 40Chapter 9 | Service52

In most cases, the control module notes a malfunctionand indicates this with alarms and shows instructionsto rectify it in the display. See "Manage alarm" for in-formation about managing alarms. If the malfunctiondoes not appear in the display, or if the display is notlit, the following troubleshooting guide can be used.

Manage alarm

In the event of an alarm, some kind of malfunction hasoccurred, which is indicated by the status lamp chan-ging from green continuously to red continuously. Inaddition, an alarm bell appears in the informationwindow.

AlarmIn the event of an alarm with a red status lamp a mal-function has occurred that the heat pump and/orcontrol module cannot remedy itself. In the display, byturning the control knob and pressing the OK button,you can see the type of alarm it is and reset it. You canalso choose to set the installation to aid mode.

info / action Here you can read what the alarm meansand receive tips on what you can do to correct theproblem that caused the alarm.

reset alarm In most cases it is enough to select "resetalarm" 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 visibleand a menu called ”alarm” is visible in the display, theproblem that caused the alarm remains. If the alarmdisappears and then returns, see the troubleshootingsection (page 53).

aid mode ”aid mode” is a type of emergency mode.This means that the installation produces heat and/orhot water despite there being some kind of problem.This can mean that the heat pump's compressor is notrunning. In this case any electrical addition producesheat and/or hot water.

Caution

Selecting "aid mode” is not the same as correct-ing the problem that caused the alarm. Thestatus lamp will therefore continue to be red.

TroubleshootingIf the operational interference is not shown in the dis-play the following tips can be used:

Basic actionsStart by checking the following possible fault sources:

The switch's (SF1) position.Group and main fuses of the accommodation.The property's earth circuit breaker.The control module's miniature circuit breaker (FA1).Correctly set load monitor (if installed).

Low hot water temperature or a lack of hotwaterThis part of the fault-tracing chapter only applies if thewater heater is installed in the system.

Closed or choked filling valve for the hot waterheater.

Open the valve.Mixing valve (if there is one installed) set too low.

Adjust the mixer valve.Control module in incorrect operating mode.

If mode "manual" is selected, select "addition".Large hot water consumption.

Wait until the hot water has heated up. Temporar-ily increased hot water capacity (temporary lux)can be activated in menu 2.1.

Too low hot water setting.Enter menu 2.2 and select a higher comfort mode.

Too low or no operating prioritisation of hot water.Enter menu 4.9.1 and increase the time for whenhot water is to be prioritised.

Low room temperatureClosed thermostats in several rooms.

Set the thermostats to max in as many rooms aspossible. Adjust the room temperature via menu1.1 instead of choking the thermostats.

Control module in incorrect operating mode.Enter menu 4.2. If mode "auto" is selected, selecta higher value on "stop heating“ in menu 4.9.2.If mode "manual" is selected, select "heating". Ifthis is not enough, select "addition".

Too low set value on the automatic heating control.Enter menu 1.1 "temperature" and adjust the offsetof the heating curve. If the room temperature isonly low in cold weather the curve slope in menu1.9.1 "heating curve" needs adjusting up.

Too low or no operating prioritisation of heat.Enter menu 4.9.1 and increase the time for whenheating is to be prioritised.

"Holiday mode" activated in menu 4.7.Enter menu 4.7 and select “Off”.

External switch for changing the room heating activ-ated.
