Heat pump function

A heat pump can use stored solar energy from rock, ground or water in order to heat a property. The conversion of energy stored in nature to property heating occurs 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 temperature in the refrigerant circuit, (2). The heat is distributed around the house in the heating medium circuit, (3).

The temperatures are only examples and may vary between different installations and time of year.

Brine circuit
In a hose, collector, an anti-freeze liquid, brine, circulates 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 considerably, from approx. 5ｰC to approx. 100 ｰ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 original temperature. The refrigerant has now completed 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 system and transports the heated water’s heat energy to the house water heater and radiators/heating coils.

Passive cooling
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.

Maintenance of S1155PC/S1255PC

Regular checks

• You should check your installation at regular intervals.
• If anything unusual occurs, messages about the malfunction appear in the display in the form of different alarm texts.

BRINE: The brine that obtains the heat in the ground is not normally consumed, but just pumped around.

LEK: Your installation includes an expansion vessel, where you can check the pressure in the system. The pressure may vary slightly due to the temperature of the fluid. The pressure should not fall below 0.5 bar.

• Ask your installer if you are unsure where the expansion vessel is located.
• Your installer can also help you to top-up if the pressure has dropped.

SAFETY VALVE S1155PC

• For installations with a water heater.
• You can find the safety valve on the incoming pipe (cold water) to the water heater.

S1255PC

• You can find the safety valve on the incoming pipe (cold water) to S1255PC.
• The water heater’s safety valve sometimes releases a little water after hot water usage. This is because the cold water, which enters the water heater to replace the hot water, expands when heated causing the pressure to rise and the safety valve to open.

The function of the safety valve must be checked regularly. Perform checks as follows:

1. Open the valve.
2. Check that water is flowing through it.
3. Close the valve

TIP: The safety valve is fitted by your installer. Contact your installer if you are unsure how to check it.

Saving tips

• Your heat pump installation produces heat and hot water.
• This occurs via the control settings you made.

Factors that affect the energy consumption are, for example, indoor temperature, hot water consumption, the insulation level of the house and whether the house has many large window surfaces. The position of the house, e.g. wind exposure is also an affecting factor.

Also remember:

• Open the thermostat valves completely (except in rooms where you want it to be cooler). This is important, as fully or partially closed thermostat valves slow the flow in the climate system, which results in S1155PC/S1255PC working at a higher temperature. This in turn can lead to increased energy consumption.
• You can lower the operating cost when away from home by scheduling selected parts of the system. This is done in menu 6 – “Scheduling”.
• If you select “Small” in menu 2.2 – “Hot water demand”, less energy is used.

Disturbances in comfort

In most cases, S1155PC/S1255PC notes a malfunction (a malfunction can lead to disruption in comfort) and indicates this with alarms, and instructions for action, in the display

Info-menu
All the heat pump’s measurement values are gathered under menu 3.1 – “Operating info” in the heat pump’s menu system. Examining the values in this menu can often make it easier to identify the source of the fault.

Manage alarm
In the event of an alarm, a malfunction has occurred and the status lamp shines with a steady red light. You receive information about the alarm in the smartguide on the display.

ALARM
In the event of an alarm with a red status lamp, a malfunction has occurred that S1155PC/S1255PC cannot remedy itself. On the display, you can see what type of alarm it is and reset it.

In many cases, it is sufficient to select “Reset alarm and try again” for the installation to revert to normal operation.
If a white light comes on after selecting “Reset alarm and try again”, the alarm has been remedied.

“Auxiliary operation” is a type of emergency mode. This means that the installation attempts to produce heat and/or hot water, even though there is some kind of problem. This could mean that the heat pump’s compressor is not in operation.
In this case, any electric additional heat produces heat and/or hot water.

Caution
Selecting “Auxiliary operation” is not the same as correcting the problem that caused the alarm. The status lamp will therefore remain red.

If the alarm does not reset, contact your installer for suitable remedial action.

Troubleshooting

If there are disturbances in comfort, users can refer to the Troubleshooting section in the user manual before contacting their installer. Regular checks should be performed as outlined in the Maintenance section to ensure the system is functioning properly.

If the operational interference is not shown in the display the following tips can be used:

BASIC ACTIONS

Start by checking the following items:

• Group and main fuses of the accommodation.
• The property’s earth circuit breaker.

  • Fill the climate system with water and check for leaks.
    In event of repeated filling, contact the installer.

THE COMPRESSOR DOES NOT START

• There is no heating or hot water demand, nor cooling demand.
  • S1155PC/S1255PC does not call on heating, hot water or cooling.
• Compressor blocked due to the temperature conditions.
  • Wait until the temperature is within the product’s working range.
• Minimum time between compressor starts has not been reached.
  • Wait for at least 30 minutes and then check if the compressor has started.
• Alarm tripped.
  • Follow the display instructions.

WHINING NOISE IN THE RADIATORS

• Closed thermostats in the rooms and incorrectly set heating curve.
  • Set the thermostats to max in as many rooms as possible. Fine-tune the heating curve via home screen heating, rather than choking the thermostats.
• • Circulation pump speed set too high.
  • Contact your installer!
• • Uneven flow over the radiators.
  • Contact your installer!

Only additional heat

ADD. HEAT ONLY
If you are unsuccessful in rectifying the fault and are unable to heat the house, you can continue running the heat pump in emergency mode, or “Add. heat only” mode, while waiting for assistance. “Add. heat only” mode means that the heat pump only uses the immersion heater to heat the house.

Set the heat pump to additional heat mode

1. Go to menu 4.1 – “Operating mode”.
2. Select “Add. heat only”.

Emergency mode

• You can activate the emergency mode both when S1155PC/S1255PC is running and when it is switched off.
• 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.
• 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.)
