General
Greenline HE is a series of heat pumps that use stored
solar energy in order to provide water-based heating and
hot water.

C6 - C11 are heat pumps with integrated hot water
heaters.
E6 - E17 are heat pumps designed to be supplemented
with an external hot water heater.
Once the heat pump has been installed and started,
there are a number of points that should be checked
regularly. This may concern an alarm triggering or
performing basic maintenance actions. If the problem is
repeated, you should contact the dealer.
2.2
Heat pump function
The heat pump consists of four main parts:
• Evaporator
Evaporates the refrigerant to gas and at the same time
transfers the heat from the collector to the refrigerant
circuit.
• Condenser
Condenses the gas to fluid again and transfers the
heat to the heating system.
• Expansion valve
Lowers the pressure of the refrigerant.
• 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.

Expansion valve
Borehole (bedrock heat)
Geothermal heating coil
• The collector circuit fluid, which is a mixture of water
and anti-freeze, circulates in the borehole/geothermal
heating coil in a plastic hose. The fluid collects stored
solar energy and with the help of the collector circuit
pump leads it into the heat pump and to the
evaporator. The temperature is then approximately
0 °C.
• The pressure of the refrigerant increases in the
compressor and the temperature of the vapour rises
to approx. +100 °C. The hot gas is then forced into the
condenser.
• In the condenser, the heat is transferred to the
house’s heating system (radiators and floor heating)
and the hot water system. The vapour is cooled 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 -10 °C. When the refrigerant passes
the evaporator it changes to vapour again.
• The heat transfer fluid is led out from the heat pump
to the borehole/geothermal heating coil to collect
new stored solar energy. The temperature of the fluid
is approx. -3 °C.
• In the evaporator, the heat transfer fluid meets the
refrigerant. The refrigerant is then in a fluid state and
is at approximately -10 °C. When the refrigerant
meets the zero degree heat transfer fluid, it starts to
boil. A vapour is formed, which is then led into the
compressor. The temperature of the vapour is 0 °C.

Energy metering
3
Energy metering
Energy metering in the heat pump is an approximation
based on the sum of the nominal emitted output during
the relevant metering period. The calculation requires
for example that the heat pump is correctly installed,
and that the flow and Δ temperatures on the hot and
cold sides are adjusted as recommended. The value
should therefore be regarded as an estimate of the
actual emitted output. The margin of error in the
calculation is normally put at 5-10%
In addition, the energy output is affected by the outdoor
temperature, the settings for the thermostat and room
controls and heat pump usage. Ventilation, indoor
temperature and hot water demand can play a deciding
role.

Control unit
4
Control unit
The control unit controls and monitors the heating and
hot water production with the heat pump and additional
heat. The monitoring function shuts down the heat
pump in the event of operational disturbances so as to
prevent damage to critical parts of the pump.
4.1
Additional heat
The heat pump can be dimensioned to cover the peak
output of the house single-handedly and does not
normally need any additional heat then. Although in that
case there can be an additional heater installed solely
for emergency operation, when the heat pump is
stationary.
The heat pump can also be dimensioned to cover the
needs of the house to a somewhat lower degree and
then will need additional heat for the time of the year
when it is coldest. The additional heat also helps in the
event of emergency operation, extra hot water and hot
water peak.
The additional heat is provided through electric
additional heat.
The control unit activates automatically the additional
heat, if necessary.
4.2
Hot water production
Hot water is heated in the hot water heater and the
control unit gives priority to hot water before the heating
of heating water according to the settings that are made.
The hot water heater is fitted with a sensor that senses
the temperature of the hot water.

9.1
Circuits for heating
• Circuit 1; the first circuit is included by default in the
control unit and is controlled by the installed flow
sensor, possibly in combination with an installed
room sensor.
• Circuit 2-4 (mixed); control of up to 3 additional
circuits is optional. Each circuit is then fitted with a
mixing valve module, circulation pump, flow sensor
and possible room sensors.
Circuits 2 through 4 cannot have a higher
flow temperature than circuit 1. This means
that underfloor heating on circuit 1 cannot
be combined with radiators on another
circuit. Room temperature reduction for
circuit 1 can affect other circuits in some
cases.
The maximum number of circuits is reduced
by one circuit for each XB2 based accessory,
such as IVT PKS 1000.
9.2
Control method for heating
• Outdoor sensor; a sensor is fitted on the outside wall
of the house. The sensor sends signals to the control
unit in 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. The customer determines the
temperature of the heating system in relation to the
outdoor temperature by setting the heat curve on the
control unit.
It is only the room where the room sensor is
located that can influence regulation of the
temperature for the relevant heating circuit.
9.3
Clock setting of heating
• Program control; The control unit offers a possibility
to define two individual programs for time control of
the heating.
• Holiday; the control unit has a program for holiday
mode, which means that during the selected period
the room temperature changes to a lower or higher
level. The program also allows switching off hot water
production.
• External control; the control unit can make settings
for external control, which means that the
preselected function is performed when the control
unit senses an input signal.
9.4
Operating modes
• With electrical additional heat; the heat pump is
dimensioned less than the house peak heating load
and electrical additional heat is permitted to cut in at
the same time as the heat pump to meet the demand,
when the heat pump cannot meet it itself. Alarm
mode, Extra hot water and Hot water peak, and if the
heat pump is off at low outdoor temperatures, the
addition is also activated.
• Outdoor sensor and room sensors (one room sensor
per circuit is possible); Control with outdoor sensor
supplemented with room sensor(s) means that one
(or several) sensors are mounted in a central location
inside the house. It is connected to the heat pump
and provides the control unit with information about
the current room temperature. The signal affects the
flow temperature. For example, it falls when the room
sensor indicates a higher temperature than the one
set. Room sensors are used when factors other than
the outdoor temperature influence the indoor
temperature of the house. For example, this can be
when a stove or fan-assisted radiator is used in the
house, or if the house is sensitive to the wind or
exposed to direct sunlight.

>> Heat curve
The heat curve constitutes the basis for the control
unit's control of the temperature on the heating water to
the circuit and indicates how high it needs to be in
relation to the outdoor temperature. The control unit
increases the temperature of the heating water when the
outdoor temperature drops. The temperature of the
heating water out to the circuit, i.e. the flow temperature
is measured by sensor T1 for circuit 1 (full name E11.T1)
and sensor T1 for circuit 2 (full name E12.T1).
Each circuit is controlled by its own heat curve. The
installer sets the type of heating for each circuit, that is
Radiator or Underfloor. The curve for Underfloor has

Heat curve set for each circuit. If the room temperature
is perceived to be too high or too low in the circuit, it is
preferable to adjust the curve.
The curve can be changed in different ways. The slope of

module 1000
10.2.1 Set point value
The heating circuit's set point value is the temperature
of the flow that the heat pump attempts to maintain.
Sometimes, the measured actual value fluctuates a bit
upward and downward depending on changes in the
outdoor temperature or a large hot water demand.
The set point value specified by the
customer/installer is most often the room
temperature, which is recalculated by the
control unit into a corresponding flow
temperature set point value. Under normal
conditions, 1 K ( °C) in room temperature
corresponds to approx. 3 K ( °C) in flow
temperature.
The set point value is normally based on:
• Current curve value (the flow temperature at the
current outdoor temperature according to the
applicable heat curve).
• Current curve influence through:
– Room sensor
– Holiday
– Active program
– External control
Set point value calculation
The set point value for the heating circuit is the current
curve value adjusted with active curve influence, if any
such exists.
• External set point value. The set point value is
determined according to input signal 0-10V where 1V
is 10 °C and 10V is 80 °C (0V triggers an alarm).
Set point value limitation
The calculated set point value is always checked against
the permitted temperature limits.
The applicable set point value T1 for Circuit 1 and the
measured actual value for T1 are used to activate and
deactivate the heat demand.
The following applies to Circuit 2, 3...: When the actual
value for the mixed circuit's T1 is low in relation to the
set point value, more heating water is shunted into the
circuit so as to maintain the set point value.
If the flow line temperature has been below the set point
value for a certain period of time, there is heat demand
and the compressor produces heat before there is a too
significant temperature reduction indoors. This happens
until the flow line temperature is a couple of degrees
higher than the set point value. (Or because Maximum
operating time for heating at hot water demand has
passed.)
Heating demand is not active during summer operation.

Hot water peak means a temporary increase in the hot

Energy savings
Inspection and maintenance
To achieve as low energy consumption as possible for a
longer period of time, we recommend that you sign an
agreement with an authorised installer concerning
annual inspection and on-demand maintenance.
Thermostat valves
The thermostat valves on radiators and floor coils can
have a negative effect on the heating system by slowing
the flow and, by doing so, the heat pump must
compensate with a higher temperature. If thermostat
valves are installed, they should be fully opened, except
in bedrooms or other areas where a lower temperature
is required. In these rooms they can be somewhat
closed.
Floor heating
Do not set a flow temperature that is higher than the
highest value recommended by the floor manufacturer.
Airing
Do not leave the windows ajar when you air. This makes
heat leave the room all the time, while the air in the room
does not become especially better. Instead, open the
windows fully for a short time.
Close the thermostat valves when you air.
Additional electric heat
Different settings (e.g. extra hot water) lead to the
activation of an additional electric heat source and
thereby to higher energy consumption.
Always select a temperature setting for hot water and
heating that is as low as possible.
