5Chapter 1 | Important informationNIBE S2125

An air/water heat pump installation uses the outdoor air to

heat up a home. The conversion of the outdoor air’s energy

into residential heating occurs in three different circuits.

From the outdoor air, (1) , free heat energy is retrieved and

transported to the heat pump. The heat pump increases the

retrieved heat’s low temperature to a high temperature in

the refrigerant circuit, (2) . The heat is distributed around

the building in the heating medium circuit, (3) .

Installation function

Outdoor air

The outdoor air is sucked into the heat pump.

The fan then routes the air to the heat pump’s evaporat-

or. Here, the air releases the heating energy to the refri-

gerant and the air's temperature drops. The cold air is

then blown out of the heat pump.

Refrigerant circuit

A gas circulates in a closed system in the heat pump, a

refrigerant, which also passes the evaporator. The refri-

gerant has a very low boiling point. In the evaporator the

refrigerant receives the heat energy from the outdoor

air and starts to boil.

The gas that is produced during boiling is routed into an

electrically powered compressor. When the gas is com-

pressed, the pressure increases and the gas's temperat-

ure increases considerably, from 0 °C to approx 80 °C.

From the compressor, gas is forced into a heat ex-

changer, condenser, where it releases heat energy to

the indoor module, whereupon the gas is cooled and

condenses to a liquid form again.

As the pressure is still high, the refrigerant can pass an

expansion valve, where the pressure drops so that the

refrigerant returns to its original temperature. The refri-

gerant has now completed a full cycle. It is routed to the

evaporator again and the process is repeated.

Heat medium circuit

The heat energy that the refrigerant produces in the

condenser is retrieved by the indoor module's water, the

heating medium, which is heated to 55 °C (supply tem-

perature).

The heating medium circulates in a closed system and

transports the heated water's heat energy to the house

radiators/heating coils.

The indoor module’s integrated charge coil is placed in

the boiler section. The water in the coil heats up the

surrounding domestic hot water.

7Chapter 2 | Installation functionNIBE S2125

S2125 is controlled in different ways depending on your

system. You control the heat pump via your indoor module

(VVM) or control module (SMO).

See the Installer Manual for the indoor module/control

module.

During installation, the installation engineer adjusts the ne-

cessary settings for the heat pump in the indoor module or

control module, so that the heat pump works optimally in

your system.

NIBE S2125Chapter 3 | Control of S21258

Control of S2125

Regular checks

When your heat pump is located outdoors some external

maintenance is required.

NOTE

Insufficient maintenance can cause serious dam-

age to S2125, which is not covered by the guaran-

tee.

CHECKING GRILLES AND BOTTOM PANEL ON

S2125

Check regularly throughout the year that the grille is not

clogged by leaves, snow or anything else.

You should be particularly vigilant during windy conditions

and/or in the event of snow, as the grille can become

blocked.

Also check that the drain holes in the bottom panel are free

from dirt and leaves.

Regularly check that condensation is routed away correctly

through the condensation pipe. Ask your installer for assist-

ance if required.

Keep free of snow and ice

LEK

Prevent snow from building up and covering the grilles and drain holes on

S2125.

CLEANING THE OUTER CASING

If necessary the outer casing can be cleaned using a damp

cloth.

Care must be exercised so that the heat pump is not

scratched when cleaning. Avoid spraying water into the

grilles or the sides so that water penetrates into S2125.

Prevent S2125 coming into contact with alkaline cleaning

agents.

9Chapter 4 | Maintenance of S2125NIBE S2125

Maintenance of S2125

In event of long power cuts

In the event of prolonged power failures it is recommended

that the part of the heating system located outdoors is

drained. Your installer has installed a shut off and drain valve

to facilitate this. Call and ask your installer if you are unsure.

Caution

Also disconnect the non-return valve (RM1.2) to

prevent the condenser from freezing.

Silent mode

The heat pump can be set to "Silent mode", which reduces

the heat pump’s noise level. This function is useful when

S2125 must be placed in noise-sensitive areas. The function

should only be used for limited periods, because S2125 might

not reach its dimensioned power.

Fan de-icing

S-SERIES – VVM S / SMO S

Menu 4.11.3 - Fan de-icing

FAN DE-ICING

Setting range: off/on

CONTINUOUS FAN DE-ICING

Setting range: off/on

Fan de-icing: Here, you set whether the "fan de-icing"

function will be activated during the next "active defrosting".

This can be activated if ice/snow sticks to the fan, grille or

fan cone, which may be noticed due to abnormal fan noise

from S2125.

"Fan de-icing" means that the fan, grille and fan cone are

heated using hot air from the evaporator (EP1).

Continuous fan de-icing: There is the option to set recurring

de-icing. In this case, every tenth defrosting will be "Fan

de-icing". (This can increase annual energy consumption.)

Updating the software

Information about updating software can be found in the

Installer Manual for your indoor module or control module.
