measurement available, the display shows the icon
for increasing and decreasing heating (see sub-
section Increase or decrease heating).
M8004 2123EN 5 (31)

If the heating circuit’s flow temperature
measurement is enabled, the flow water
temperature is displayed next to the circuit number.
● In the figure, flow water temperature is 32°C.
If the heating circuit’s room temperature
measurement is enabled, the relevant room
temperature is displayed instead.
● In the figure, room temperature is 22°C.
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). A positive value will
increase room temperature, and a negative value will decrease the temperature.
As changes in room temperature are slow, you should change this setting by one or
two degrees at a time. Wait for one or two days for the change to become noticeable.
The increase or decrease heating setting changes the circuit’s heating curve by moving
each of the curve’s points up or down by the selected value. In practice, this has the
same effect as parallel displacement of the curve. If you change the curve manually,
the increase or decrease in heating will be reset.

Stop heating
temperature
(summer break)
Heating will be stopped, when the long-term outdoor temperature average is higher
than this temperature. Heating will resume, when the long-term outdoor temperature
average is lower than this temperature.
● In most cases, the value should be set slightly below the desired room
temperature.
● Usually, the value should be set to +10...+15°C.
Outdoor
temperature, avg.
An automatically calculated long-term outdoor temperature average.
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.
● For floor heating, the maximum flow temperature setpoint is usually around
35°C (concrete floors) or 45°C (wooden floors).
● 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.
In most cases, the minimum flow temperature should be set at or slightly above the
required room temperature. Usually, the value should be set to +20...+25°C.
*It is not advisable to use the heat pump to cure floor structures. If curing floors:
● Keep the temperature considerably lower than usual (typically no more than 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).
M8004 2123EN 15 (31)

Device settings → Heating Circuit 1 → Settings → Room temperature
Temperature optimization adjusts the flow water temperature value (determined by the heating curve)
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
● In floor heating systems, this can be achieved only if the system’s heating manifold does not feature
its own independent zone control.
● In radiator heating systems, the heat pump will be able to control the indoor temperature as long as
radiator valves (thermostat or precontroller) do not limit radiator flow.
OFF
Temperature optimization is not in use.
Temperature
optimization Used
Temperature optimization is enabled.
Gain factor
The unit’s controller adjusts the flow temperature (determined by the heating curve)
based on the measured indoor temperature. The greater the gain factor, the greater
the change.
● Wait for at least two or three days to see if the change has made a difference,
then readjust accordingly.
The settings for Circuit 2 and 3 are identical to Circuit 1 settings.
Heating curve
The heating curve indicates the temperature of flow water pumped into the heating
circuit at different outdoor temperature points. Usually, the installation company takes
care of heating curve configuration. Curve values should be tuned in during the first few
heating seasons.
The flow water temperature can be adjusted using a six-point heating curve.
An example of typical adjustments
1. If the room temperature is too cold when the outdoor temperature is 0°C, slightly increase the flow
water 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.
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).
The Home/Away function allows you to select between the Normal mode and the
Reduced mode. With the Schedule function, you can schedule the system to switch
between the Normal and the Reduced mode on different weekdays and at different
times.
No room temperature measurement available or
temperature optimization disabled
Room temperature measurement active and
temperature optimization enabled
16 (31) M8004 2123EN

If room temperature optimization is disabled, the selected operating mode will either
increase (+) or decrease (–) the target temperature of flow water (determined based on
the heating curve) by the set temperature difference value. The setting for the Normal
operating mode is also shown in the Home view.
Wait for at least two or three days to see if the change has made a difference, then
adjust the values if necessary.
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 water temperature in the curve is +35 °C and the Reduced
setting is –3°C, the target temperature for flow water will be +32 °C.
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. Correspondingly, changing the operating mode will directly increase or
decrease the room temperature setting. The room temperature setpoint changes the
flow water temperature through room temperature optimization.
Wait for at least two or three days to see if the change has made a difference, then
adjust the values if necessary.

Setpoints for
operating modes
There are three operating modes for domestic hot water heating: Normal, Boost,
and Reduced.
The Home/Away function allows you to select between the Normal mode and the
Reduced mode. With the Schedule function, you can schedule the system to switch
between the Normal and the Reduced mode on different weekdays and at different
times.
● When the domestic hot water boost function is activated from the Home view,
the operating mode will switch to Boost (and the tank will be heated up to the
boost temperature).
● The Boost function can be used only if using the in-line heater for domestic hot
water heating has been enabled (i.e. the additional heater’s Mode for heating
setting is either After compressor or With compressor).

SETTINGS → LEGIONELLA INHIBITION
This function heats up the domestic hot water to a high temperature to prevent bacterial growth.
Temperature is kept at a high level for a specific period of time (the clean-up period). To achieve sufficient
temperature levels, the domestic hot water in the tank can be heated up using both the compressor and
the unit’s electric immersion heater.
● If domestic hot water temperature remains mostly at or above +55 °C, this function is usually not
necessary.
● The boost function can be used only if using the electric immersion heater for heating domestic hot
water has been enabled (i.e. the additional heater’s Mode for heating setting is either Legionella
inhibition, After compressor or With compressor).
