1.3 Basic concepts
Buffer tank Heating circuit’s storage tank.
Brine Liquid that circulates in the brine circuit (evaporator circuit), usually a mixture
of water and ethanol.
Brine circuit The brine circuit is a long loop of pipe embedded in the earth filled with brine,
a cold mixture of ethanol and water. The brine circuit extracts heat from the
ground.
Brine pump The brine pump circulates brine inside and between the brine circuit and the
heat pump.
Coefficient of
Performance, COP
Ratio between the electricity used by the heat pump and the heating
provided. If a heat pump’s COP is 3.5, it will generate 3.5 watts of heating for
every watt of electricity.
Condenser pump Pump that circulates heat-transfer fluid (heating water) to the condenser to
warm up and from the condenser to the heating circulation.
Degree minutes The heat pump has a degree minute counter that determines when functions
are activated and how long they remain active. The more a measured value
differs from a setpoint, the faster the related function will be activated.
● Example: The start delay for the in-line heater is 90 °Cmin. Flow
setpoint is 60 °C, and measured flow temperature is 45 °C. This gives a
temperature difference of 15 °C. Each minute, 15 °Cmin is deducted from
the counter. The in-line heater will switch on in 6 minutes.
M8004 2308EN 3 (49)

Domestic hot water Hot tap water.
Electric immersion heater A heating cartridge built into a domestic hot water tank or heating circuit
buffer tank. Provides supplementary heating or acts as a backup heater.
Flow In heating circuits, ‘flow’ refers to water that has been heated up by the heat
pump and fed into the heating circuit. In the brine circuit, ‘flow’ refers to brine
returning from the heat pump to the brine circuit.
Flow temperature Temperature in a fluid fed into a circuit (water in heating circuits, brine in the
brine circuit).
Heating circuit A circuit that transfers the heat generated by the heat pump to radiators or
floor heating pipes. A building can have several heating circuits – one for
living areas and another for wet spaces, for example.
Heating curve A six-point curve that determines the heating provided by the heat pump at
different outdoor temperatures.
Heating water Water heated up by the heat pump and used for heating the domestic hot
water tank or a heating circuit buffer tank. If the heat pump is connected
directly to a heating circuit (without a buffer tank), heating water is used to
heat the heating circuit (as ‘flow’ water).
In-line heater An electric heater cartridge built into or connected to a fluid line. In Oilon heat
pumps, an in-line heater is often built into the condenser flow pipe to provide
supplementary heating or to act as a backup heater.
Outdoor temperature Outdoor temperature is the primary control variable in space heating; it
determines how much heating will the heat pump provide.
Room optimization A feature that adjusts the heat pump’s operation based on measured room
temperature. Heat pump operation is still dependent on outdoor temperature
and heating curves.

Heating circuits and their temperature
To change the heating circuit displayed in the Home
view, tap the circuit’s number.
The Heating circuit window appears. Select
another circuit, and tap OK.
Circuit 1 is now displayed in the Home view. If the heating circuit has no room temperature
measurement available, the display shows the icon
for increasing and decreasing heating (see sub-
section Increase or decrease heating).
If the heating circuit’s flow temperature
measurement is enabled, the flow water
temperature is displayed next to the circuit number.
If the heating circuit’s room temperature
measurement is enabled, the relevant room
temperature will be displayed instead.
Increase or decrease heating
The Home view includes an icon for increasing or decreasing heating in the selected
circuit. This icon will not be displayed, if the circuit has no room temperature
measurement available (or room temperature optimization has been disabled).
M8004 2308EN 7 (49)

When active, the setting moves the circuit's heating curve by moving each of the
curve’s points up or down by the selected value. This has the same effect as moving
the curve sideways. If you change the curve manually, the increase or decrease in
heating will be reset.
As changes in room temperature are slow, change the setting by one or two degrees at
a time. Wait for one or two days for the change to become noticeable.

Heating curve
The heating curve determines the flow temperature: the temperature of water pumped
into the heating circuit at different outdoor temperature points. Usually, the installation
company takes care of heating curve configuration.
The heating curve consists of six adjustable points. Curve values should be tuned in
during the first few heating seasons.
The impact of different operating modes
There are three operating modes for space heating: Normal, Boost, and Reduced
(see section Home or Away function and Schedules).
No room temperature measurement available or
temperature optimization disabled
Room temperature measurement active and
temperature optimization enabled
Room temperature optimization disabled
The selected operating mode will either increase (+) or decrease (–) the target flow
temperature by a set amount. This influences room temperature indirectly, see the table
below.
16 (49) M8004 2308EN

Radiator heating, guideline values Floor heating, guideline values
Room temperature +1 °C → Increase by 6 (+6)
Room temperature −1 °C → Decrease by 6 (−6)
Room temperature +1 °C → Increase by 3 (+3)
Room temperature −1 °C → Decrease by 3 (−3)
For example, if the flow temperature in the curve is +35 °C and the Reduced setting is
–3 °C, the target flow temperature will be +32 °C.
After changing a setting, wait for at least two or three days to see if the change has
made a difference. The setting for the Normal operating mode is also shown in the
Home view.
Room temperature optimization enabled
If the system is equipped with an indoor temperature sensor and temperature
optimization is enabled, this setting will change the room temperature setpoint directly
instead. Changing the operating mode will directly increase or decrease the room
temperature setting. The room temperature setpoint influences flow temperature
through the room temperature optimization function.
After changing a setting, wait for at least two or three days to see if the change has
made a difference.

Max. flow
temperature
The maximum flow temperature when the outdoor temperature matches the
Design outdoor temperature setting. The system will keep the flow temperature
determined by the heating curve below this temperature value.
●Typical setting, floor heating: conrete floors +35 °C, wooden floors +45 °C
● Check the temperature value from the floor or floor heating supplier (or from the
applicable plans and specifications).
Min. flow
temperature
The system will keep the flow temperature determined by the heating curve above
this temperature value.
●Typical setting: +20...+25 °C
● Set the minimum flow temperature at or slightly above the required room
temperature.
M8004 2308EN 17 (49)

Device settings → Heating Circuit 1 → Settings → Room temperature
Flow temperature is primarily determined by the heating curve. Temperature optimization adjusts flow
temperature based on room temperature measurements and a setpoint. An indoor temperature sensor is
required, and the heat pump’s automation must be able to control the indoor temperature.
To enable temperature optimization
●Floor heating: disable independent zone control (if present) in the heating manifold.
●Radiator heating: ensure that radiator valves (thermostat or precontroller) are always fully open.
OFF
Temperature optimization is not in use.
Temperature
optimization In use
Temperature optimization is enabled.
Gain factor
The unit’s controller adjusts flow temperature based on the measured indoor
temperature. The greater the gain factor, the greater the change.
● Wait for at least 2–3 days to see if the change has made a difference.
The settings for Circuit 2 and 3 are identical to Circuit 1 settings.
3.3.1 Typical heating curve adjustments
1. If the room temperature is too cold when the outdoor temperature is 0 °C, slightly
increase the flow setpoint at outdoor temperature points −2 °C and +8 °C.
2. Wait for at least two or three days to see if the change has made a difference.
3. Adjust the curve if necessary.
3.3.2 Curing concrete floors with a heat pump
It is not advisable to use the heat pump to cure floor structures.
● Keep the temperature considerably lower than usual (maximum: +20 °C) before the
concrete slab has cured and after the floor has been tiled.
● Increase the temperature gradually over a longer period of time.
● Keep the temperature as even as possible.
● Check the temperature values and curing times from the floor or floor heating
supplier (or from plans and specifications).
