F110 – An excellent choice

F110 is a heat pump that has been developed to supply your house with ventilation and hot water in a cost-effective and environmentally friendly manner. With an integrated water heater, immersion heater and control system, reliable and economical hot water production is obtained.  F110 is equipped with a control computer to give you good comfort, good economy and safe operation. Information about status, operating time and all temperatures in the heat pump are shown on the clear display.

EXCELLENT PROPERTIES FOR F110:

• EU directive
  Conventional incandescent bulbs were phased out of the market several years ago. This also now applies to electric water heaters. Heat pump water heaters are one way of satisfying the new EU directive and F110 has been developed specifically to fulfil that directive. F110 consumes approximately 1/3 of the power of a corresponding conventional electrical water heater. This gives great savings and F110 therefore pays for itself quickly.

• Integrated water heater
  There is a water heater integrated in the heat pump, which is insulated with environmentally friendly cellular plastic for minimal heat loss.

• Scheduling hot water and ventilation
  Hot water and ventilation can be scheduled for each day of the week or for longer periods (vacation).

• Display with user instructions
  The heat pump has a display with easy-to-understand menus that facilitate setting a comfortable hot water level.

• Simple troubleshooting
  In the event of a fault, the heat pump display shows what happened.

The heat pump – the heart of the house

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

Heat pump function

The heat pump uses the heat that is in the air to heat up the domestic hot water. The conversion of the air’s energy to hot water occurs in three different circuits. Heating energy is recovered from the outgoing exhaust air, surrounding indoor air or outdoor air (1) and transported to the heat pump. The heat pump raises the recovered heat’s low temperature to a high temperature in the refrigerant circuit (2). The heat is then distributed to the water heater (3).

1. The air
   Air is transferred from outdoors or from the rooms via ducts to the heat pump.

2. The fan then routes the air to the heat pump’s evaporator. Here, the air releases the heating energy to the brine and the air’s temperature drops significantly. The cold air is then blown out of the house or into a room in the house.
   The fan then routes the air to the heat pump’s evaporator. Here, the air releases the heating energy to the brine and the air’s temperature drops significantly. The cold air is then blown out of the house or into a room in the house.
   Refrigerant circuit

3. A liquid, a refrigerant, circulates in a closed system in the heat pump which also passes the evaporator. The refrigerant has a very low boiling point. In the evaporator the refrigerant receives the heat energy from the air and starts to boil.

4. 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°C to approx. 80°C.

5. From the compressor, gas is forced into a heat exchanger, or condenser, where it releases heat energy to the domestic hot water, whereupon the gas is cooled and condenses to a liquid form again.

6. 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.
   Domestic hot water

7. The heat energy that the refrigerant produces in the condenser is retrieved by the domestic hot water which is heated to the set temperature. A liquid, a refrigerant, circulates in a closed system in the heat pump which also passes the evaporator. The refrigerant has a very low boiling point. In the evaporator, the refrigerant receives the heat energy from the air and starts to boil.

Maintenance of F110

REGULAR CHECKS
Your heat pump requires minimal maintenance after commissioning. On the other hand, it is recommended that you check your installation regularly.If something unusual occurs, messages about the malfunction appear in the display in the form of different alarm texts. See alarm management on page 19.

Exhaust air installation : Cleaning the ventilation devices
The building’s ventilation devices should be cleaned regularly with, for example, a small brush to maintain the correct ventilation. The device settings must not be changed.

NOTE
If you take down more than one ventilation device for cleaning, do not mix them up.

Cleaning the air filter
The air filter in F110 has to be cleaned regularly; how often depends, for example, on the quantity of particles in the ventilation air. Test, to find out what is most appropriate for your installation.

Caution
The efficiency of the installation can be impaired by a dirty air filter.

1. Switch off the fan in F110 by holding the standby button for 3 seconds. (Display turns off.)
2. Pull out the filter cassette.
3. Remove the filter and shake/vacuum it clean.
4. Check the condition of the filter and replace if needed.
5. Carry out assembly in reverse order.

Even if the filter looks clean, dirt collects in it and this affects the efficiency of the filter. For this reason, replace the filter at least once a year. A new filter can be ordered via a dealer for NIBE or at nibe. eu.

NOTE
Water or other liquids must not be used for cleaning.\

Safety valve
The safety valve must be checked about four times a year. The safety valve is reached by removing the front panel.

1. Open the valve by turning the knob anti-clockwise carefully.
2. Check that water flows through the overflow pipe. When water stops coming out of the overflow pipe the valve is defective and must be replaced.
3. Close the valve by releasing it. If it does not close automatically when released, turn it anti-clockwise slightly.

The safety valve sometimes releases a little water after hot water has been used. This discharge is caused by the expansion through heating of cold water entering the water heater, resulting in a pressure increase, whereby the safety valve opens.

EMPTYING
Drain the heat pump of water as follows:

1. Switch off the circuit fuse or pull out the plug.
2. Close the shut-off valve (turn clockwise).
3. Open the safety/drain valve (turn the knob slowly anticlockwise until it remains in the raised position).
4. Ensure air supply by opening all hot water taps.

Caution
The heat pump is started when the supply cable is connected to an earthed socket.

F110 – at your service

Set the ventilation

MENU 1 – VENTILATION

• Setting range: normal and speed 1-4
• Default value: normal

This menu is only shown with exhaust air installation. The ventilation in the accommodation can be temporarily increased or reduced here. When a new speed has been selected, a countdown is initiated. After 4 hours, the ventilation speed returns to the normal setting. The fan speed is shown in brackets (in percent) after each speed alternative.

TIP
If longer time changes are required use the holiday function.

Caution
The heat pump requires a minimum ventilation flow in order to work properly. An insufficient ventilation flow can result in an alarm and blocking of compressor operation.

Set the hot water capacity

OVERVIEW: Sub-menus

For the menu HOT WATER there are several sub-menus. Status information for the relevant menu can be found on the display to the right of the menus. temporary lux Activation of temporary increase in the hot water temperature. Status information displays “off” or what length of time of the temporary temperature increase remains. comfort mode Setting hot water comfort. The status information displays what mode is selected, “economy”, “normal” or “luxury”. scheduling Scheduling hot water comfort. Status information “active” displays if the scheduling is active right now, the status information “set” displays if the scheduling is set but not active. advanced Setting periodic increase in the hot water temperature.

MENU 2.1 – TEMPORARY LUX

• Setting range: 3, 6 and 12 hours and mode “off” and “one time increase”
• Default value: “off”

Caution
If comfort mode “luxury” is selected in menu 2.2 no further increase can be carried out. The function is activated immediately when a time period is selected and confirmed using the OK button. The remaining time for the selected setting is shown to the right. When the time has run out F110 returns to the mode set in menu 2.2. Select “off” to switch off temporary lux.

MENU 2.2 – COMFORT MODE

• Setting range: economy, normal, luxury
• Default value: normal

The difference between the selectable modes is the temperature of the hot tap water. Higher temperature means that the hot water lasts longer.

• economy : This mode produces less hot water than the others, but is more economical.
• normal : Normal mode gives a larger amount of hot water and is suitable for most households.
• luxury : Lux mode gives the greatest possible amount of hot water.

In this mode, the immersion heater is used to heat hot water as well as the compressor, which increases operating costs.

MENU 2.3 – SCHEDULING

What hot water comfort the heat pump is to work with can be scheduled here. Scheduling is activated/deactivated by ticking/unticking”activated”. Set times are not affected at deactivation.

• Activated : Scheduling for the selected period is activated here. Set times are not affected at deactivation.
• Day : Select which day or days of the week the scheduling is to apply to here. To remove the scheduling for a particular day, the time for that day must be reset by setting the start time to the same as the stop time. If the row “all” is used, all days in the period are set according to that row.
• Time period : The start and stop time for the selected day for scheduling are selected here.
• Comfort mode : Set the hot water comfort that is to apply during scheduling here.

TIP
If you wish to set similar scheduling for every day of the week start by filling in “all” and then changing the desired days.

Caution
If the stop time is earlier in the day than the start time it means that the period extends past midnight. Scheduling always starts on the date that the start time is set for. If time periods overlap each other at midnight, the time period that starts after midnight is prioritised.

MENU 2.9 – ADVANCED
Menu advanced has orange text and is intended for the advanced user. This menu has a submenu

MENU 2.9.1 – PERIODIC INCREASE
period

• Setting range: 1 – 90 days

Disturbances in comfort

In most cases, the heat pump notes operational interference (operational interference can lead to disturbance in hot water comfort) and indicates this with an alarm in the display.

Info menu
All the heat pump measurement values are gathered under menu 3.1 in the heat pump menu system. Looking through the values in this menu can often simplify finding the source of the fault.

Manage alarm

In the event of an alarm, a malfunction has occurred, which is indicated by an alarm symbol in the display.

ALARM

• In the event of an alarm a malfunction has occurred that F110 cannot rectify itself. The display shows what type of alarm it is and lets you reset the alarm. You can also choose to set the heat pump to rescue mode
• reset alarm In many cases it is sufficient to select “reset alarm” to correct the problem that caused the alarm. If the alarm recurs, the problem that caused the alarm remains. If the alarm initially disappears and then returns, you should contact your installer.
• aid mode “aid mode” is a type of emergency mode. This means that the heat pump produces hot water despite there being some kind of problem.
• This can mean that the heat pump’s compressor is not running. In this case the immersion heater produces hot water.

Caution
Selecting ”aid mode” is not the same as correcting the problem that caused the alarm. The alarm symbol will remain displayed.

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

Caution
You need the product’s serial number for servicing and support.

Technical data

Detailed technical specifications for this product can be found in the installation manual (nibe. eu).

Glossary

• ADDITIONAL HEAT
  Additional heat is the heat produced in addition to the heat supplied by the compressor in your heat pump. Additional heat can be an immersion heater for example.

• COMPRESSOR
  Compresses the gas state refrigerant. When the refrigerant is compressed, the pressure and the temperature increase.

• CONDENSER
  Heat exchanger where the hot gas state refrigerant condenses (cools and becomes a liquid) and heats the hot water.

• DISTURBANCES IN COMFORT
  Disturbances in comfort means unwanted changes in hot water comfort, e.g. that the temperature of the hot water is too low. A malfunction in the heat pump can sometimes be noticed in the form of a disturbance in comfort. In most cases, the heat pump notes operational interference and indicates this with alarms and shows instructions in the display.

• EVAPORATOR
  Heat exchanger where the refrigerant evaporates by retrieving heat energy from the air which then cools.

• EXPANSION VALVE
  A valve that reduces the pressure of the refrigerant, whereupon the temperature of the refrigerant drops.

• HEAT EXCHANGER
  Device that transfers heat energy from one medium to another without mixing mediums. Examples of different heat exchangers include evaporators and condensers.

• REFRIGERANT
  A substance that circulates around a closed circuit in the heat pump and that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and when condensing gives off heating energy.

• SUPPLY TEMPERATURE
  The temperature of the heated water that the heat pump sends out to the heating system. The colder the outdoor temperature, the higher the supply line temperature becomes.
