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 concern 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 pres-
sure 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 boil-
ing point changes when the pressure
changes. However, the boiling point of
the refrigerant is as low as approxi-
mately -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 fluid to the refrigerant circuit.
2. Condenser
The condenser condenses the vapour to fluid 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 refriger-
ant 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

FOR THE USER
Heat transfer fluid in. The heat pump collects stored solar energy. It contains a heat transfer fluid 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 fluid it is led into the evaporator. The temperature is then approximately 0ºC.
In the evaporator, the heat transfer fluid meets the refrigerant. At this stage, the refrigerant is in a fluid state
and is at approximately -10ºC. When the refrigerant meets the zero degree heat transfer fluid it starts 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 floor heating) and the hot
water system. The vapour is cooled in the condenser and becomes fluid. 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 flow.
The heat transfer fluid is led out from the heat pump to the rock to collect new stored solar energy. The heat
transfer fluid is led out from the heat pump to the rock to collect new stored solar energy. The temperature of
the fluid 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/floor heating and
hot water is for showers and taps. Hot water is heated in a hot water heater.
The hot water heater is fitted 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 tempera-
ture influence 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 influence
regulation of the temperature.
Note

The room sensor influence is inhibited
24 hours after using clock setting for

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.
Curve 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 curve
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 satisfied 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 compres-
sor switches off. The heat pump starts automatically when the return
temperature drops.
Curve slope:
2-4 Normal setting for floor 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 tempera-
ture 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 tempera-
ture 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 adjust-
ment.
If it is still difficult to get a comfort-
able 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 effective
in cold weather conditions.

Fine-tune the heat curve
The heat curve can also be fine-tuned. Fine-tuning means that you offset
the heat curve in parallel. Fine-tuning is done from the Temp. fine-tune
menu. The diagram for fine-tuning shows how the dashed line has been
offset upwards in parallel. This means the heating has been fine-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.

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 informa-
tion 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 tempera-
ture 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 flow sensor. If an extra curve with mixing valve
is used, for example, for a floor heating system, you can see the temperature on the flow
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 fitted.
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 fluid 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 fluid 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 fluid that is led into the heat pump.
