1.8 WORKING PRINCIPLE

A heat pump operates similarly as a refrigerator. In a refrigerator, liquids evaporate due to received thermal energy from the surrounding air and this energy is emitted at a desired spot

during condensation (Carnot’s cycle). A heat pump works in the opposite direction: it accepts

thermal energy from the surrounding air and emits it in heated premises, using the natural

heat collector of the environment. Ground and surface water, earth’s warmth, solar energy

and ambient air can be used as energy sources. The system is composed of four units: evaporator, compressor, condenser and damper. Heat energy is transferred via the coolant. In the evaporator, the coolant receives heat energy and evaporates. In the compressor, the vapour is compressed, which makes it heat up intensively. This hot vapour transmits thermal energy from the condenser to the heating water and liquefies. In the damper, the coolant expands (pressure reduces to the starting pressure, from there it proceeds to the evaporator and the cycle repeats).

Inverter heat pumps use variable-speed compressors. Traditional heat pumps use fixed power/rotation speed compressors. In inverter compressors, the compressor speed constantly adapts to the heat losses of the room and the energy value of the source (air, brine or water, depending on the system). In traditional heat pumps, the power of the compressor is always the same. Compressor starts with full power and when it achieves the desired values/temperatures, it shuts off and waits until it restarts. Inverter heat pumps work for a longer period, but with lower power (adjusting to the premises), which means lower consumption of electric energy.

If the “Pause” symbol is displayed, the heat pump is manually switched off!

b) Heating or cooling indicator

The symbol indicates that heating or cooling by ambient temperature or thermostat is activated, or is activated due to manual operation mode! Heating or cooling is activated or deactivated based on the ambient temperature! Factory setting of enabled heating or cooling based on the ambient temperature:

Heating – 18 °C Cooling – 25 °C These values can be set as you wish.

Example:

Heating activation temperature is set to 18 °C. This means that when the average

ambient temperature exceeds 18 °C, the heat pump will stop heating. The sun

symbol will disappear from the display.

When the average ambient temperature drops below 18 °C, the sun symbol

reappears on the display and the heat pump will reinitiate heating of the premises, unless an additional thermostat is used. In that case, the heat pump will require the deactivation of the thermostat.

c) Activating the heating of domestic water

This symbol is visible on the display only when the heat pump is used for heating domestic water. The symbol is always visible on the display, unless the domestic hot water timer is used. If the domestic water timer is used, a different symbol appears in the domestic water heating regime.

d) Communication

This symbol displays the communication status of the heat pump.

A light blue symbol indicates normal communication. A grey symbol indicates loss of communication. In this case, an error symbol is displayed as well. Please notify an authorized service person immediately!

e) Display of the current Operation mode

The heat pump displays the current Operation mode. Heating

This symbol appears when the heat pump is in the “Defrosting” mode.

This symbol appears when the timer for the preparation of domestic water is on

This symbol appears when the timer for heating / cooling is active.

g) Warning or Error

An exclamation mark appears on the screen, cautioning about an error.

• Minor error; considered as a warning. Heat pump operates normally, but an authorized service person should be informed immediately!

• Major error; to ensure safety of the system and the heat pump, the pump is shut

off. If the “Emergency Operation” feature is on, the heat pump will continue

working, but only with backup heating sources! Please inform an authorized service person immediately!

h) Power on/off

Heat pump power on/off. Heat pump on means that the system is active for heating, cooling and preparation of hot domestic water! The symbol is blue! Heat pump off means that the system is switched off except for the Anti-freezing protection which is on! The symbol is grey!

Anti-freezing protection protects the system from freezing. The heat pump automatically checks the water temperature. If it drops below a certain value, potentially causing system damage due to system water freezing, it turns on to increase the water temperature to a safe temperature level.

5 QUICK SETTINGS

5.1 PARALLEL MOVE OF THE HEATING CURVE

What is a parallel move of the heating curve? At start-up, the heating curve is adjusted according to the heating system (Floor heating system, Radiators, Fan coils) and desired room temperature. The setting can be changed from the Main screen, but only the complete move of the heating curve and not each reference point separately. The heating curve can be raised or lowered for 3 °C (-3 to +3). By raising the heating curve for 2-3 °C would mean an increase of the room temperature for approx. 1 °C.

The graph below shows a parallel move of the heating curve – lowering of the heating curve for 2°C

First the window for parallel move of the first heating circuit appears. To access the setting of the parallel move for the second heating circuit press . Second page appears with the

setting for the second heating circuit.

With buttons ˝+˝ or ˝– ˝ the heating curve can be changed for the desired value. Confirm the setting with button ˝OK˝.

5.1.3 SETTING THE DHW TEMPERATURE

By pressing on the DHW temperature, an additional window appears.

With buttons ˝+˝ or ˝– ˝ the DHW set temperature can be changed for the desired value. Confirm the setting with button ˝OK˝.

Domestic hot water settings depend on the user’s habits. The recommended setting for domestic hot water is between 47 °C and 50 °C.

Traditional systems (boilers) use smaller domestic water storage tanks, so the temperature must be significantly higher than in a heat pump system, which causes higher costs of domestic hot water preparation! In principle, a heat pump system is planned to store 50 litres of water per person. This means that a family of four needs a minimum of 200 litres of hot water per day.

Note:

Mixing of cold and warm water in a mixing tap differs according to the systems of how domestic water is heated. If the traditional domestic water heating system is used, less hot water is mixed with cold than in a heat pump system.

By pressing on the room temperature display, an additional window appears.

6.3 SETTINGS

Heating

The heat pump enables two heating circuits, meaning that it can control two different temperature modes. Heating/cooling circuit 1 and Heating/cooling circuit 2

When only one heating circuit is in use, the heating settings are defined in the menu “Heating/cooling circuit 1“!

6.3.1 Heating/Cooling Circuit 1

Page 49

6.3.1.1 Heating/Cooling Stops Based on Water ∆T

Temperature setting that allows overheating of the heating system for the set value.

The recommended setting is 2 °C! This enables efficient operation of the Inverter technology

and brings the highest savings. Please note, that we allow the Heat Pump to overheat the system, to maintain a low working speed and to avoid a frequent stopping and starting of the compressor.

6.3.1.2 Heating/Cooling Restarts Based on ∆T

The compressor restarts based on the set values of heating/cooling circuits.

The recommended value is 2 °C. This enables efficient operation of the Inverter technology

and brings the highest savings.

6.3.1.3 ∆T Compressor Speed Reduction

This setting tells the system when will the compressor start lowering its working speed. The

recommended value is 2 °C. This enables efficient operation of the Inverter technology and

brings the highest savings.

For example:

If the set/calculated temperature is 30°C and the ˝∆T COMPRESSOR SPEED REDUCTION˝ is set to 2°C, the compressor will work at its max working speed (check chapter ˝Max Compressor Working Speed˝) till it reaches 28°C. At a 28,1°C and above the compressor

speed will start to decrease towards the lowest working speed of the compressor.

6.3.1.4 Set temp. For cooling

Setting the desired cooling water temperature of the first cooling circuit is set (the second circuit is set in the menu “Heating/Cooling Circuit 2”).

6.3.1.5 Heating Curve

The heating curve mode is based on the condition that the lower the ambient temperature is, the higher the water temperature for the heating of facility is. This heating curve mode can help the heat pump to achieve a higher COP (efficiency rate) and increase the feeling of comfort in the house.

As the level of home insulation and people’s feeling of cold can differ, the factory set curve

may not be appropriate for everybody. The heating curve may be set according to customers needs. The basic setting of the heating curve is made upon the first start-up of the heat pump. The start-up must be performed by an authorized service person! The basic setting is always adjusted according to the system that is installed (underfloor heating, radiators, convectors (Fan Coil)). To determine the basic heating curve, we also need to take into account the insulation of the facility!

The heat pump enables two heating circuits with different heating curves.

NOTE:

It is recommended to reset only the space heating water temperatures (figure above on the right). Resetting ambient temperatures for the heating curve affects both heating circuits.

EXAMPLE

Example:

The customer wants the room temperature to be 21 °C, but the heat pump heats the rooms to 22 °C. In

this case the heating curve must be lowered. On page 3, all temperatures need to be lowered by 2-3 °C, which means that the room temperature will be lower by 1 °C. If the room temperature is lower than the desired temperature, the temperature values must be increased.

Page 51

6.3.1.7 Room temp. effect on Heating Curve

When the temperature sensor ˝TR˝ is mounted in the living area, this function can make small corrections of the heating curve, depending on the set “Ideal Room Temp. in Heating”.

Note:

This feature does not mean temperature control by room temperature, but only a correction of the heating curve! If this feature is on and the temperature in the room (where the TR room temperature sensor is located) still exceeds the set ideal value, the heating curve settings should be reset!

6.3.1.8 Ideal Room temp. in Heating

Relates to parameter (6.3.1.6). The setting is active only when the feature “Room Temp. Effect on Heating Curve” is

enabled.

6.3.1.9 Ideal Room temp. in Cooling

6.3.1.10 Set Temperature for heating – without heating curve

Set temperature for the heating water system – without heating curve. When the heating curve is disabled, the heat pump operates with fixed system heating water temperature. Weather-related control of the heating circuit is disabled, which can lead to higher heating costs!

NOTE:

The parameters in grey are protected by a service code!

6.3.1.11 Low Temperature Limit

This is for setting the lowest possible temperature that the end customer can set, without accessing the service level. This setting applies for the heating mode and cooling mode.

6.3.1.12 High Temperature Limit

This is for setting the highest possible temperature that the end customer can set, without accessing the service level. This setting applies for the heating mode only.

Default setting is 40°C, meaning if a system with higher desired temperatures is used (radiators, Fan-coils…) the Limitation must be increased.

6.3.1.13 Mixing Valve

Enabling or Disabling the Mixing Valve for the first Heating/Cooling Circuit (Heating/Cooling Circuit 1). A check in a box means that the Heating/Cooling Circuit 1 uses a Mixing Valve for the Circuit. Please note that if the Mixing Valve is Enabled a temperature sensor (TV1) must be added after the Mixing Valve.

Page 52

6.3.2 Heating/Cooling circuit 2

6.3.2.1 Heating/cooling Circuit 2

A check in a box means that the heating/cooling circuit 2 is on.

6.3.2.2 Set temp. for Cooling

Setting the desired space cooling water temperature in Cooling Circuit 2. The desired temperature of Cooling Circuit 2 is set.

6.3.2.3 Set Temp. For Heating – without heating curve

Set temperature of space heating water– without heating curve. When the heating curve is off, the heat pump operates with fixed space heating water temperature. Weather-related control of the heating circuit is off, which can lead to higher heating costs!

6.3.2.4 Mixing Valve

Enabling or Disabling the Mixing Valve for the second Heating/Cooling Circuit (Heating/Cooling Circuit 2). A check in a box means that the Heating/Cooling Circuit 2 uses a Mixing Valve for the Circuit.

If the Mixing Valve is Enabled, a temperature sensor (TV2) must be added after the Mixing Valve.

Page 53

NOTE:

If the second heating circuit is active and the room thermostat is not used, a wire must be placed between TH and COM. If a wire is not placed between TH and COM, the heat pump will heat the buffer tank according to the lower temperature demand.

6.3.2.5 Heating Curve

6.4 DHW SETTINGS

EXAMPLE

Example:

The customer wants the room temperature to be 21 °C, but the heat pump heats the rooms to 22 °C. In

this case the heating curve must be lowered. On page 3, all temperatures need to be lowered by 2-3 °C,

which means that the room temperature will be lower by 1 °C. If the room temperature is lower than the

desired temperature, the temperature values must be increased.

Page 55

6.4.1.1 Setpoint DHW

Setting of the desired temperature for domestic water.

6.4.1.2 DHW Restart ∆T Setting

Domestic hot water restart setting.

Example:

Desired temperature of domestic water is 47 °C, and the domestic hot water restart ∆T

setting is 5 °C. (47–5=42)

This means that the heat pump will restart the heating of domestic water when the temperature drops below 42 °C! Recommended domestic hot water restart ∆T setting is 5 °C!

6.4.1.3 Shifting Priority

The heat pump has absolute priority for the preparation of domestic hot water. With this feature, the priority adjusts to the heat losses when the ambient temperature reaches a certain point. This feature is used in new buildings that still lack insulation and that will be without insulation for at least one heating season.

6.4.1.3.1 Enabling or Disabling the Shifting Priority function:

Disabled (default setting) – the Heat Pump will switch to Heating mode only when the

desired DHW temperature is reached. Enabled – the Heat Pump will decide based on the temperatures of the heating system if it should switch to heating although the DHW set temperature is not reached yet.

For example:

Set temperature for DHW is 47°C and the Heat Pump is currently working in DHW mode.

The actual DHW temperature is 44°C, meaning it still has to heat up the DHW for another

3°C, before it can switch to heating mode (heating the House). In that moment, the Unit sees

that the temperature of the Heating water for the heating system is dropping for a certain value, meaning it is a high risk of undercooling the house. It switches to Heating mode to provide heat to the house. When the temperature is in safe level, or the max set time for heating is exceeded, the Heat Pump switches back to DHW mode to heat up the DHW to the desired value, before it switches back to Heating mode.

6.4.1.3.2 Shifting Priority Starting Temperature

Only valid if Shifting Priority enabled! Setting the Ambient temperature to activate the Shifting Priority Function. If the Shifting Priority Function is enabled it will not be active before the Ambient temperature

falls below a certain value (Shifting Priority Starting temperature).

6.4.1.4 Sanitary Water Min. Working Hours

Only valid if Shifting Priority enabled! This setting is set in Minutes! The Heat Pump will try to heat up the DHW for a minimum time before it switches to Heating, even if all other conditions for Shifting Priority are met.

6.4.1.5 Heating Max. Working Hours

Only valid if Shifting Priority enabled! This setting is set in Minutes!

Page 56

When the Heat Pump switches to Heating mode in Shifting priority mode, it will allow the unit to stay in Heating mode only for a certain time, before it switches back to heat up the DHW.

6.4.1.6 Allowable temp. Drift in Heating

Only valid if Shifting Priority enabled! Setting for the max. Temperature drift in heating system during DHW heating mode. Only when this value is exceeded, the Unit will switch to heating.

6.4.1.7 DHW Backup Heater for Shifting Priority

Only valid if Shifting Priority enabled!

Disabled – Backup heater will work only according to the normal back-up stings. Enabled – Backup Heater will help to faster heat up the DHW.

6.4.1.8 DHW ECO Operation

Enable or Disable this function.

Disabled (default setting) – normal operation of DHW working mode Enabled – the compressor speed never exceeds 50% of the compressor working speed,

which is determent by the ambient temperature (see chapter ˝Compressor Speed˝).

NOTE:

In normal operation (DHW ECO Operation – Disabled), the compressor speed is limited by the Ambient temperature, meaning that the compressor speed will decrease when ambient temperature is Increasing.

6.4.1.9 Ambient Temp. to Start DHW ECO Operation

Setting the Ambient temperature when the DHW ECO Operation function will be active. Please note, that if the Ambient temperature is higher than this setting, the DHW ECO Operation will not be active!

6.14 ELECTRICAL UTILITY LOCK

6.14.1 Electrical Utility Lock

Default setting is Disabled. Electrical Utility Lock or EUL is used in some countries, where the Industry has a high demand on electrical power one or multiple times a day. The electricity distribution companies send a signal to Households that stops all high power electrical consumption systems. The heat pump belongs to this group, meaning it needs to stop during this time. If there is an additional heating source that is not in this EUL group, it can be automatically switched on during this period (see chapter 6.13.3). A potential free contact is used and connected to the terminals ES and COM. There are two possibilities of signal used for this function – Normally open (NO) and normally closed (NC). If this function is enabled and a signal comes the compressor will stop for heating mode,

DHW mode and Cooling mode. For systems with active Electrical Utility Lock a buffer is recommended, so that the heat

stored in the buffer can be used for heating the house.

Page 73

6.14.2 Operation Signal for Electrical Utility Lock

Default setting is Normally Open. Signal type can be selected according to the signal received from the distribution system.

Normally Open – function will be active when ES and COM are short-circuited. Normally Closed - function will be active when ES and COM are open.

6.14.3 HBH During Electrical Utility Lock

Default setting is Disabled.

Enabled – During EUL active, the HBH (K2) will switch ON. Disabled – No additional heating sources will switch ON.

By connecting an additional heating source to the second stage of Backup heating, it can be switched ON during the EUL is active.

Normally the HBH is the second sage of electrical heater, but the internal second stage electrical heater can be disconnected and on its place an additional heating source connected. HBH is switched ON by the contactor K2. By using its contacts an additional heating source can be switched ON like a gas boiler.

6.14.4 P0 during Electrical Utility Lock

Default setting is Disabled.

Enabled – P0 will work during EUL is active. Disabled – P0 will STOP during EUL is active. Note:

P0 is the internal circulating pump.

6.14.5 Heating Eco Operation

Default setting is Disabled. Heating ECO Function (or Bivalent function) is for switching ON an additional heating source like a Gas boiler in could whether conditions. It this case, the compressor will STOP. When active it will switch on contactor K2 (HBH – second stage internal electrical heater). Meaning the second stage is connected to an additional heating source.

For example:

The Heating ECO Operation is enabled and the temperature to start the Heat ECO operation is set to -20°C. A Gas boiler is connected to the system as an additional heating source, controlled by the contactor K2 (HBH): When the ambient temperature falls below -20°C, the compressor will stop and the heat pump will switch on the contactor K2 (HBH) to switch on the Gas boiler for heating the house. When the ambient temperature rises again over -20°C, the Heat pump will stop the Gas boiler and switch on the compressor for heating the house.

6.15.7 MODE SWITCH DURING DEFROSTING

With this function off, the unit will start to defrost in the current working mode. If the

water temperature is under 23°C, the unit will stop with error if there is not enough

energy for safe defrost. If this function is active, the unit will switch the working mode to the system that has water temperature higher than 23°C to make a safe defrost. After defrosting is done, the unit will switch back to required working mode.

6.15.8 MODE SIGNAL OUTPUT

With this function, you can determine when the MS contact will be active. You can select the activation during:
