For the user
Note
It is important as the user that you read through this chapter. Under no circumstances may the user make settings that are designed for the installer. This can cause serious malfunction of the heat pump.
Important information
Your new heat pump represents a new generation of heat pumps from Bosch. It contains numerous functions to control the temperature and production of hot water in the house. The control unit includes a control and monitoring function that stores important settings about the heat pump’s operation and maintenance. The settings are made by the installer and the user via a control panel on the front of the heat pump. Settings intended for the user, are presented under the headings Basic functions and Extra functions.
When the heat pump has been installed and started there are a number of points you should check regularly. This may concer n an alarm triggering or performing basic maintenance actions. First of all you should perform these actions yourself. This manual describes each step in detail. If the problem remains you should contact your dealer.

FOR THE USER
This is how your heat pump works
The heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and environment friendly heating. The easiest way to describe how a heat pump works is to say it works like a refrigerator, however, the other way round. In a refrigerator, heat is moved from the inside to the outside. In a heat pump, heat stored in the ground, rock or water, is moved into the house. The heat pump collects a few degrees of the stored solar energy. The heat is led into the house via a hose. The temperature is then increased in the heat pump and the heat is distributed to the house’s heating system.
The heat pump collects stored solar energy
Boiling point in relation to the pressure:
The boiling point of different liquids varies with pressure, the higher the pressure, the higher the boiling point. For example, water boils at +100ºC at normal pressure. Double the pres­sure and water boils at +120ºC. Half the pressure and water then boils at +80ºC. The refrigerant in the heat pump acts in the same way, the boil­ing point changes when the pressure changes. However, the boiling point of the refrigerant is as low as approxi­mately -40ºC at atmospheric pressure. Consequently, it is also suitable for low heat source temperatures.
Note
Rock heat Soil heat Lake heat
The heat pump consists of four main parts:
1. Evaporator
The evaporator evaporates the refrigerant to gas and transfers heat
from the heat transfer fl uid to the refrigerant circuit.
2. Condenser
The condenser condenses the vapour to fl uid again and transfers the
heat to the heating system.
3. Expansion valve
Lowers the pressure of the refrigerant.
4. Compressor
The compressor increases the pressure of the refrigerant.
These four main parts are linked in three circuits. A refrigerant circulates in the heat pump, which in some parts of the circuit is in a liquid state and in other parts in a gas state. Read more about the properties of the refriger­ant in the sidebar to the right.
See the detailed description of the technologies used in the heat pump on the next page.
Technology in and around the heat pump
This is how your heat pump works
7
FOR THE USER
Heat transfer fl uid in. The heat pump collects stored solar energy. It contains a heat transfer fl uid which is a solution of water and antifreeze, glycol. The antifreeze mixture collects the heat from the rock and with the help of the heat transfer fl uid it is led into the evaporator. The temperature is then approximately 0ºC.
In the evaporator, the heat transfer fl uid meets the refrigerant. At this stage, the refrigerant is in a fl uid state and is at approximately -10ºC. When the refrigerant meets the zero degree heat transfer fl uid it star ts to boil. It then forms a vapour, which is led into the compressor. The temperature of the vapour is 0ºC.
The pressure of the refrigerant increases in the compressor and the vapour temperature rises from 0ºC to approximately +100ºC. The warm gas is then forced into the condenser.
The condenser transfers the heat to the house’s heating system (radiators and fl oor heating) and the hot water system. The vapour is cooled in the condenser and becomes fl uid. The pressure in the refrigerant is still high when it is led on to the expansion valve.
The refrigerant pressure is lowered in the expansion valve. At the same time, the temperature also drops to approximately -10ºC. When the refrigerant passes the valve and the evaporator it changes to vapour again. There is also a valve for regulating refrigerant fl ow.
The heat transfer fl uid is led out from the heat pump to the rock to collect new stored solar energy. The heat transfer fl uid is led out from the heat pump to the rock to collect new stored solar energy. The temperature of the fl uid is approximately -3ºC.

FOR THE USER
Control unit
The control unit is the brains of the heat pump. It makes sure the heat pump gives the best energy savings and that it runs for many years. The control unit controls and monitors the heating and hot water supply in your house. The monitoring function is especially important. It shuts down the heat pump in the event of operational disturbances so that no critical parts are damaged.
Additional heat gives more output
When the heat pump can not manage to heat the house by itself, for example, if there is a considerable drop in the outdoor temperature, the control unit ensures the additional heat source is connected. Together the heat pump and additional heat guarantee the right temperature in the house. Additional heat is provided by a built in electric cassette. Additional heat can never completely take over the heating from the heat pump. It only adds the output necessary for the heat pump to be able to produce the right temperature. When the heat pump can once again manage heating on its own the additional heat is automatically disconnected.
Hot water is given priority over heating water
In a house with water based heating a difference is made between heating water and hot water. The heating water is for radiators/fl oor heating and hot water is for showers and taps. Hot water is heated in a hot water heater. The hot water heater is fi tted with a sensor that senses the temperature of the hot water. LWM models include a hot water heater in the heat pump while LW models have an external hot water heater. The heating water passes through the hot water cylinder’s outer shell and heats up the hot water heater’s inner tank. The control unit makes sure the heating of hot water is always given priority over the heating of the heating water. This means you never need to be without hot water. The control unit controls a three-way valve that switches between heating the heating water and hot water. Once the hot water has been heated the three-way valve switches so that the heating water is heated.

FOR THE USER
The control unit’s two methods to control the heat pump
The control unit uses two different methods to control the heat pump. These two methods are: Control with an outdoor sensor and Control with an outdoor sensor supplemented with a room sensor.
Control with outdoor sensor
Control with an outdoor sensor is the most common method used by the control unit to control the heat pump. A sensor is installed on the external wall of the house. It sends out signals for regulating the heat pump. Control with an outdoor sensor means that the heat pump automatically regulates the heating in the house depending on the outdoor temperature. If the outdoor temperature drops, i.e. it becomes colder; the radiators inside the house will become warmer.
You determine the temperature of the radiators, in relation to the outdoor temperature, with the help of a number of settings such as selecting the heat curve on the control unit. A lower curve gives higher energy savings.
Control with outdoor sensor supplemented with room sensor
Control with an outdoor sensor supplemented with a room sensor means that you also place a sensor in a central position inside the house. This is connected to the heat pump and provides the control unit with information about the room temperature. The signals affect the control unit’s settings (curves) and ensure the heat pump gives the best possible energy savings.
This control method is used when factors other than the outdoor tempera­ture infl uence the indoor temperature. Examples include the use of a stove or fan-assisted radiator or if the house is sensitive to the wind.
It is only the room where the room sensor is located that can infl uence regulation of the temperature.
Note

Basic functions - Customer level 1
Set the heating
It is easy to set the heating level on the heat pump. However, before we explaaccord. to clockow to do this it is important to understand the relation between the outdoor temperature, return temperature and heat curve slope. The easiest way to explain the relation is with a heat curve.
Heat curve
You use the heat curve to help set the indoor temperature you would like. The heat pump is controlled by the outdoor temperature. When the weather becomes colder, the heat pump ensures more heating is produced automatically.
Return temperature:
The return temperature is the temperature of the water that returns to the heat pump from the radiators. The water led out from the heat pump to the heating system is normally 7-10ºC higher than the return temperature. When the outdoor temperature is -10ºC and curve 4 is set, the pump attempts to keep the return water at approximately 40ºC.
Outdoor temperature:
The outdoor temperature determines how much heating the heat pump should produce. A sensor placed outdoors sends signals to the control unit, which then adjusts the heat pump.
Cur ve slope:
You can change the curve slope to increase or decrease the heating in the house. The scale is between 0-10.
On delivery the heat pump cur ve slope is set to position 4. This means that the return temperature is +35ºC when it is 0ºC outdoors.

FOR THE USER
In cold weather (below +5ºC):
If you are not satisfi ed with the indoor temperature when it is colder than +5ºC outdoors, you need to change the slope of the heat curve. This is what to do:
1. Press the Heat button in the initial menu.
2. Press the Adjust button.
3. Turn the menu dial clockwise to increase the heating. Turn the menu dial anti-clockwise to lower the heating. (Adjust in small increments, 0.2-0.6 units, is usually enough.)
4. Save the new value by pressing the Save button.
Basic functions - Customer level 1
Dashed line:
If the return temperature exceeds 57ºC an alarm is given and the compres­sor switches off. The heat pump star ts automatically when the return temperature drops.
Curve slope:
2-4 Normal setting for fl oor heating.. 4-6.5 Normal setting for radiators. 7-10 Abnormal high setting.
From the heat curve we see that curve slope 4 gives a return tempera­ture of +35ºC when it is 0ºC outdoors. If the outdoor temperature drops we can see that the return temperature increases. The colder the outdoor temperature the higher the return temperature. At an outdoor tempera­ture of approximately -30ºC we see the curve slope has nearly reached the limit value (+57ºC) for the return temperature.
You should wait at least two days when increasing or decreasing the heating before making a new adjust­ment.
If it is still diffi cult to get a comfort­able indoor temperature at an outdoor temperature around 0ºC, despite several attempts, you should adapt the heat curve. Read about how to “adapt the curve” in the section Extra functions – Customer level 2 / Temperature settings / Adapting the heat curve.
Note
Change the curve slope
The heat pump’s production of heat is adjusted by increasing or decreasing the curve slope in the Temp. incr. / decr. menu. This is especially ef fective in cold weather conditions.

Fine-tune the heat curve
The heat curve can also be fi ne-tuned. Fine-tuning means that you offset the heat curve in parallel. Fine-tuning is done from the Temp. fi ne-tune menu. The diagram for fi ne-tuning shows how the dashed line has been offset upwards in parallel. This means the heating has been fi ne-tuned in a positive direction and the heat pump will be instructed to maintain a higher temperature on the return water at all outdoor temperatures.
Outdoor temperature (ºC)

By using the menu dial on the control panel the fi ne-tuning line has been moved up so the heat pump produces more heat.
In warm weather (above +5ºC):
If you are not satisfi ed with the indoor temperature when it is warmer than +5ºC outdoors, you should offset the cur ve in the Temp. fi ne-tune menu. This is what to do:
1. Press the Heat button in the initial menu.
2. Turn the menu dial clockwise until you reach the menu Temp. fi ne­tune.3.
3. Press the Adjust button.

All menus relating to temperature sensors
All the menus associated with the heat pump temperature sensors are shown below. Note that you cannot make any settings in these menus, only read the current values. Some menus are standard for all models of Ecolane SE while others are only available in combination with different accessories. The sensors give an alarm if the temperature is outside of the permitted range/values.
Note
All sensors are not included as standard on the heat pump, some are available as accessories for different application areas. See more informa­tion under respective menus.
The menu shows the temperature in the heating system’s return, i.e. the water from the radiators back to the heat pump accord. to clockeating mode. The temperature varies with the outdoor temperature.
The menu shows the outdoor temperature. Some deviation compared to the true tempera­ture may occur due to thermal radiation from the house to the installed outdoor sensor.
The menu shows the set and present temperature in the lower section of the outer container in the hot water heater. The temperature is approximately 5ºC lower than the temperature of the hot water inside the inner container.
The menu only applies together with a fl ow sensor. If an extra curve with mixing valve is used, for example, for a fl oor heating system, you can see the temperature on the fl ow water in the circuit. The temperature varies with the outdoor temperature.
The menu only applies together with a room sensor. The menu shows the set point value and present temperature in the room where the sensor is fi tted.
The menu shows the compressor’s working temperature. The temperature varies between 70ºC and 125ºC during operations.
The menu shows the temperature of the radiator water as it leaves the heat pump. It varies depending on the outdoor temperature and whether the heat pump is accord. to clockot water production mode.
The menu shows the temperature of the water that is led into the heat pump. It varies depending on the outdoor temperature and whether the heat pump is accord. to clockot water production mode. The heat pump stops at 57ºC for reasons of safety.
The menu shows the temperature of the heat transfer fl uid that is led into the heat pump from the bore hole or the ground. It can vary between -5ºC to +15ºC during a season.
The menu shows the temperature of the heat transfer fl uid that is led out of the heat pump to the bore hole or the ground. Normally, during operations, it is 1.5 - 5.0 degrees lower than the heat transfer fl uid that is led into the heat pump.

Temperature settings
Proceed as follows to access the temperature settings for the heating on Customer level 2:
1. Press the Heat button until Access = CUSTOMER2 is displayed.
2. Press the Menu button.
3. Press the Select button and scroll through the menus using the menu dial.
Fine-tune the heat curve
You can “break” the heat curve up or down every fi fth outdoor degree. For example, you can make a hump in the curve at 0ºC. Navigate to menu 1.3, press Select and turn the menu dial until 0°C is displayed in the upper left part of the menu. Press Adjust and turn the dial to increase or decrease the return temperature. The change must not exceed 1 - 2°C. Press Save and wait at least 24 hours prior to any further adjustment. The purpose of breaking the curve is to be able to infl uence the heat pump’s heat production at extra sensitive outdoor temperatures.
Room sensor infl uence
The menu is only shown for heat pumps having a room sensor installed. You use the menu to set how much the room sensor should infl uence the heat curve. A higher value will have a greater effect. Please note that the room sensor only fi ne-tunes the heat curve. Consequently, it is important the basic setting of the heat curve’s slope and fi ne-tuning are correct.
Holiday mode
The menu is only shown for heat pumps having a room sensor installed. The holiday function gives you the possibility to choose a number of days when the room temperature will be lowered to 15ºC (the temperature is not adjustable). When the days have passed the heat pump returns to the normal heating setting. Hot water production is not affected by the holiday function.
Remote control
The menu is only shown for heat pumps having a room sensor installed. In addition, special remote control equipment is needed. This equipment is available as an accessory. You can switch between the remote control mode and normal mode using a telephone.
Summer disconnection
The function means the heat pump only produces hot water when the outdoor temperature rises above the set value.

Set extra heat curve with mixing valve
If you have fl oor heating combined with radiators, you should set an extra heat curve with mixing valve. The mixing valve is a valve that lets water through in different amounts. It prevents the fl oor from becoming too hot and destroying the fl ooring. The menu is only displayed when there is an extra fl ow sensor, T4 (GT4), on the heat pump. You set the extra heat curve using two menus: Mix. valve incr/decr and Mix. valve fi ne-tune.
Increase or decrease the mixing valve
1. Press the Heat button until Access = CUSTOMER2 is displayed.
2. Press the Heat button.
3. Turn the menu dial clockwise until you reach the menu Mix. valve incr/ decr.4.
4. Press the Adjust button.
5. Turn the menu dial clockwise to choose a higher heat cur ve.
Turn the menu dial anti-clockwise to choose a lower heat curve.
6. Save the new value by pressing the Save button.
Note
The initial position of the fl oor heat­ing circuit is heat curve 2. The scale covers the range 0 to 10. Extra heat curve with mixing valve only works with an extra fl ow sensor T4 (GT4).
Fine-tune the mixing valve
1. Press the Heat button until Access = CUSTOMER2 is displayed.
2. Press the Heat button.
3. Turn the menu dial clockwise until you reach the menu Mix. valve fi ne-tune.
4. Press the Adjust button.
5. Turn the menu dial clockwise to set an upward, parallel offset on the curve.
Turn the menu dial anti-clockwise to set a downward parallel offset on the
curve.
6. Save the new value by pressing the Save button.
Note
The example describes how to fi ne­tune the extra heat curve. The scale covers the range -10ºC to +10ºC.

Timer control
Open the setting menus for timer control like this:
1. Press the Heat button until Access = CUSTOMER2 is displayed.
2. Press the Menu button.
3. Turn the menu dial clockwise until you access the menu Timer control settings (menu 4).
4. Press the Select button and scroll through the menus using the menu dial.
Clock setting of the heat pump according to clock
The function Clock setting HP accord. to clock is for those who want the heat pump to produce different amounts of heat at different times of the day and on different days of the week. This allows you to make further energy savings. The room sensor T5 (GT5) infl uence is inhibited 24 hours after using clock setting for the heating, or after any type of external control of the heat pump. This allows the heating to return to ordinar y settings. In practise this means that should clock setting of the heating apply each night, then the room sensor has no function except temperature readings.
Example:
You want to set the heat pump so that it maintains a 3ºC lower radiator tem­perature on Mondays between 22:00 and 06:00.
1. Turn the dial clockwise until you access the menu Clock setting HP accord. to clock (menu 4.1).
2. Press the Select button.
3. Turn the menu dial clockwise to choose the day. Now press the Adjust button to select the weekday with the symbol ^. Turn the menu dial clockwise one step to activate the start day. The weekday now has a capital letter.
4. Press the right-hand arrow (->) until the cursor reaches the fi rst two zeros (00).
