4 Pipe connections

Docking alternativesSMO 20 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 52 for a list of the accessoriesthat can be used with SMO 20.

Installations with SMO 20 can produce heating andhot water. Cooling can also be produced, but it de-pends on the heat pump that is used.

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 installations alternative is suitable for more com-plex installations with a focus on comfort.

SMO 20 (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.Immersion heater (EB20) in the water heater/accumu-lator tank (CP10) is used during the time to producehot water if the heat pump (EB101) is used for heatingthe building at the same time.

The additional heat can also be used if a higher temper-ature in the hot water is required than the heat pumpcan produce.

During cooling operation (requires compatible heatpump) reversing valve (EQ1-QN12) switches to thecooling system (EQ1). If several simultaneous demandsoccur while there is a cooling demand the installationreacts differently. In event of a hot water demand thereversing valve (EQ1-QN12) switches back and hotwater is produced until the demand is fulfilled. In eventof a heating demand the reversing valve (EQ1-QN12)instead switches periodically between the demands.

In event of a cooling demand the reversing valveswitches back to basic mode (heat/hot water).

Optional connectionsRoom sensorSMO 20 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 20 display the sensor must be in-stalled. Connect the room sensor to terminal block X2:7and X2:10.

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.

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.

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.

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

Step 1 is connected to terminal block X2:2 on the extrarelay card (AA7).

Step 2 is connected to terminal block X2:4 on the extrarelay card (AA7).

Step 3 or immersion heater in the water heater/accu-mulator tank is connected to terminal block X2:6 onthe extra relay card (AA7).

Any control voltage is connected to terminal block X2:1,3 and 5 on extra 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 X2 (see page 19) whichis selected in menu 5.4.

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.

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. If

the 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.

Menu 1.9.1 - curve

heating

Setting range: 0 - 15

Default value: 9


Setting range: 0 - 9

Default value: 0

The prescribed heating curve for your house can beviewed in the menu heating curve . 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. Select the heating curve and read off how thesupply temperature changes at different outdoortemperatures here. If there is access to cooling the samesettings can be made for the cooling curve.

Curve coefficient

The slopes of the heating /cooling curves indicate howmany degrees the supply temperature is to be in-creased/reduced when the outdoor temperaturedrops/increases. A steeper slope means a higher supplytemperature for heating or a lower supply temperaturefor cooling at a 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 curve is set when the heating installation is in-stalled, but may need adjusting later. Normally, thecurve will not need further adjustment.


Caution

In the event of making fine adjustments of theindoor temperature, the curve must be offsetup or down instead, this is done in menu 1.1temperature .

Curve offset

An offset of the curve means that the supply temperat-ure changes as much for all the outdoor temperatures,e.g. that a curve offset of +2 steps increases the supplytemperature by 5 C at all outdoor temperatures.

Flow line temperature– maximum and minimumvalues

Because the flow line temperature cannot be calculatedhigher than the set maximum value or lower than theset minimum value the heating curve flattens out atthese temperatures.

Caution

Underfloor heating systems are normally maxflow line temperature set between 35 and 45°C.

Must be restricted with underfloor coolingmin. flow line temp. to prevent condensation.

Check the max temperature for your floor withyour installer/floor supplier.

The figure at the end of the curve indicates the curveslope. The figure beside the thermometer gives thecurve offset. Use the control knob to set a new value.Confirm the new setting by pressing the OK button.

Curve 0 is an own curve created in menu 1.9.7.

To select another curve (slope):1. Press the OK button to access the setting mode2. Select a new curve. The curves are numbered from

0 to 15, the greater the number, the steeper theslope and the greater the supply temperature.Curve 0 means that own curve (menu 1.9.7) isused.

3. Press the OK button to exit the setting.

To read off a curve:1. Turn the control knob so that the ring on the shaft

with the outdoor temperature is marked.2. Press the OK button.3. Follow the grey line up to the curve and out to the

left to read off the value for the supply temperatureat the selected outdoor temperature.

4. You can now select to take read outs for differentoutdoor temperatures by turning the control knobto the right or left and read off the correspondingflow temperature.

5. Press the OK or Back button to exit read off mode.

TIP


If it is cold outdoors and the room temperatureis too low, increase the curve slope by one in-crement.

If it is cold outdoors and the room temperatureis too high, lower the curve slope by one incre-ment.

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 whileheating. When the contact is on, the heat curve offsetis changed by the number of steps selected in themenu. If a room sensor is installed and activated thedesired room temperature (°C) is set.

49Chapter 9 | ServiceSMO 20

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 50).

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.

NOTE

To select aid mode an alarm action must beselected in menu 5.1.4.

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).

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.

Check any external switches.Air in the climate system.

High room temperatureToo high set value on the automatic heating control.

Enter menu 1.1 (temperature) and adjust the heatcurve offset downwards. If the room temperatureis only high in cold weather the curve slope in menu1.9.1 (heating curve) needs to be adjusted down.

External switch for changing the room heating activ-ated.

Check any external switches.

Low system pressureNot enough water in the climate system.

Top up the water in the climate system.

The compressor does not startThere is no heating requirement.

The heat pump does not call on heating nor hotwater.

Temperature conditions tripped.Wait until the temperature condition has been re-set.

Minimum time between compressor starts has notbeen reached.

Wait 30 minutes and check if the compressor hasstarted.

Alarm tripped.Follow the display instructions.

Additional heating onlyIf you are unsuccessful in rectifying the fault and areunable to heat the house, you can, whilst waiting forassistance, continue running the heat pump in ”add.heat only”. This means that additional heating only isused to heat the house.

Set the installation to additional heat mode1. Go to menu 4.2 operating mode.2. Mark ”add. heat only” using the control knob and

then press the OK button.3. Return to the main menus by pressing the Back

button.
