5Chapter 1 | Important informationNIBE S1155PC/S1255PC

A heat pump can use stored solar energy from rock,

ground or water in order to heat a property. The conver-

sion of energy stored in nature to property heating oc-

curs in three different circuits. In the brine circuit, (1),

free heat energy is retrieved from the surroundings and

transported to the heat pump. The heat pump increases

the retrieved heat's low temperature to a high temper-

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

around the house in the heating medium circuit, (3).

The temperatures below are only examples and may

vary between different installations and times of year.

Brine circuit

An anti-freeze liquid (brine) circulates in a hose

(collector) from the heat pump out to the heat

source (rock/ground/lake). The energy from the

heat source is stored by it heating the brine a

few degrees, from about –3 °C to about 0 °C.

The collector then routes the brine to the heat

pump’s evaporator. Here, the brine releases

heat energy and the temperature drops a few

degrees. The liquid then returns to the heat

source to retrieve energy again.

Refrigerant circuit

Another liquid circulates in a closed system in

the heat pump, a refrigerant, which also passes

the evaporator. The refrigerant has a very low

boiling point. In the evaporator the refrigerant

receives the heat energy from the brine and

starts to boil.

The gas that is produced during boiling is routed

into an electrically powered compressor. When

the gas is compressed, the pressure increases

and the gas's temperature increases consider-

ably, from approx. 5°C to approx. 100°C.

From the compressor, gas is forced into a heat

exchanger, condenser, where it releases heat

energy to the heating system in the house,

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 origin-

al temperature. The refrigerant has now com-

pleted a full cycle. It is routed to the evaporator

again and the process is repeated.

Heat medium circuit

The heating energy that the refrigerant releases

in the condenser is retrieved by the heat pump's

boiler section.

The heating medium circulates in a closed sys-

tem and transports the heated water's heat

energy to the house water heater and radiat-

ors/heating coils.

The brine can also be circulated via a mixing

valve to a heat exchanger. There the brine cools

the heating system's water so that comfort

cooling can be maintained during the hotter

periods of the year.

THE STATUS LAMP

The status lamp shows how well your system is operat-

ing. It:

• lights up white during normal operation.

• lights yellow in emergency mode.

• lights red in the event of a deployed alarm.

• flashes white during active notice.

• is out when S1155PC/S1255PC is switched off.

If the status lamp is red, you receive information and

suggestions for suitable actions on the display.

TIP

You also receive this information via myUplink.

THE USB PORT

Above the display, there is a USB port that can be used

e.g. for updating the software. Visit myuplink.com and

click the "Software" tab to download the latest version

of the software for your installation.

THE ON/OFF BUTTON

The on/off button has three functions:

• start

• switch off

• activate emergency mode

To start: press the on/off button once.

To switch off, restart or activate emergency mode: press

and hold the on/off button for 2 seconds. This brings up

a menu with various options.

For hard switch off: press and hold the on/off button for

5 seconds.

To activate emergency mode when S1155PC/S1255PC

is switched off: press and hold the on/off button for 5

seconds. (Deactivate the emergency mode by pressing

once.)

THE DISPLAY

Instructions, settings and operational information are

shown on the display.
