Settings menu overview
The setting menu is build in a way, which makes it easy to use.
Ventilation: Here are settings made concerning the ventilation of the house.
Domestic hot water production: Here are settings made concerning the domestic hot water production.
General settings: Here are settings made concerning both ventilation and domestic hot water and
service settings.
Information: Here you find the eventlog together with an overview of the current settings for the unit.
Emergency stop ventilation: The ventilation should not be shut down entirely, as it can cause problems
with condensed water in the ducts and unit. But in an emergency situation, e.g. a fire in a nearby
factory, where you are asked to go inside your house and shut doors and windows and shut down your
ventilation system, it is possible to shut down the ventilation via the emergency stop ventilation.

User and installer rights
In the setting menu both user, installer and factory settings are shown.
• Settings without any lock can be set by all
• Settings with a white lock can only be set by installers
• Settings with a red lock can only be set by Nilan
The reason why some settings are locked for the user, is because it requires a certain amount of
knowledge about how the unit works in order to change these settings, and if they are set wrongly the
unit does not work properly and can be damaged.

Ventilation
Filter settings
The filter alarm is factory set using a timer set at 90 days between filter changes. This interval can be
changed and adapted to meet local requirements, or if an F7 filter is installed, for example, which is
replaced at longer intervals.
It is also possible to deselect the filter alarm. This is usually done in apartment buildings when the
caretaker changes the filters according to a schedule and does not want the residents calling when
there is a filter alarm if he is a day late.
Settings for supply air filters and extract air filters are set separately. The unit leaves the factory with
a G4 filter as standard, but a F7 pollen filter can be purchased for outdoor air. The life expectancy of
the two types of filter differ.

Operating mode
It is possible to provide the unit with an input which determines whether it will operate in Auto, Heating
or Cooling.
Ventilation
Operating mode Settings:
Standard setting:
Description:
Auto/ Heating/ Cooling
Auto
Auto : The unit operates in accordance with the set
values.
Heating : The unit operates in accordance with the set
values, but is not set to perform cooling.
Active cooling has been blocked and the bypass
damper will not open.
Cooling : The unit operates in accordance with the set
values, but is not set to perform heating.
Active heating and the after heating element have
been blocked.
With this setting the unit can perform cooling in winter
operation under the correct conditions.
The functions Heating and Cooling override the weekly schedule, and can be used in situations such as
the following:
Heating
A weekly schedule has been made in which the room temperature is lowered between 8.00 and 16.00
during the day, when the residents are at work or school. During the autumn half-term they no longer
wish to lower the daytime temperature as they are at home that week. Instead of cancelling the weekly
schedule, this can be overridden by setting the unit to heating mode. The unit now operates in
accordance with the desired room temperature, which can be set on the front of the touch-panel.
Cooling
A large modern house with extensive south-facing windows can start having overheating problems as
early as March/April, if the sun is shining form a cloudless sky. As the outdoor temperature maybe only
is 8 °C, the unit will be running in winter mode, with a setting which prevents it from cooling. This
limitation can be overridden by setting the unit to cooling mode. The unit will try to cool the indoor air,
if the right conditions are present. Cooling will take place via bypass and at high indoor temperatures
with active cooling via the heat pump.
ATTENTION
The system will automatically change to Auto on the next change in the weekly schedule, is such
is programmed.

Fan speed adjustment
Stepless adjustment between 20% and 100% is available for the four fan speeds. It is also possible to
adjust supply air (inlet air) and extract air (outlet air) separately, which is a great advantage when
balancing the ventilation system.
Ventilation

Humidity control
The unit has a built-in humidity control to control the ventilation relative to the average humidity, in
order to maintain a good relative humidity in the house.
If the average humidity in the house is below a set level (factory setting 30%), it is possible to reduce
the ventilation to avoid further drying of humidity in the house. It will typically only be needed for
shorter periods during the winter.
The humidity control has a further feature that allows increased ventilation if the humidity level gets
high, for example, if you take a bath. It reduces the risk of mold formation in the bathroom, and in most
cases you avoid dew on the mirror in the bathroom.
The humidity control system follows the average air humidity measured over the previous 24 hours. In
this way, the system automatically adapts to summer and winter conditions.
Ventilation
Humidity control
↳Low humidity level Settings:
Standard setting:
Description:

Settings active cooling
Depending on architecture, the home may require cooling during the summertime. Compact P has an
integral heat pump, primarily used for production of domestic hot water. The heat pump has a
reversible cooling cycle, and in the summer time it is able to cool the supply air while simultaneously
producing domestic hot water. Thus, in principle, heating the domestic water is "free of charge".
The heat pump is able to cool the supply air up to 10°C. and, in order to make it as efficient as possible,
it is advisable to raise the ventilation level when cooling is required.
However, it must be emphasised that it does not function like an air conditioning unit, because of the
low air change. Instead, by cooling the supply air, the indoor air is dehumidified, thus giving a pleasant
indoor climate even when indoor temperatures are high.
Ventilation
Active cooling settings
↳Allow active cooling Settings:
Standard setting:
Description:

case of active cooling.
↳Fan speed when cooling Settings:
Standard setting:
Description:

Level 3
This shows the fan speed level which the unit is to use
during cooling.
This requires that the "High fan speed when cooling" is
enabled.
↳Minimum cooling supply temp. (ºC) Settings:
Standard setting:
Description:
5 ↔30 °C
5 °C
Here the minimum supply air temperature is set for
the air inlet during cooling mode.
↳Cooling priority to hot water Settings:
Standard setting:
Description:
On / Off
Off
Here the minimum supply air temperature is set for
the air inlet during cooling mode. The standard setting
is set low enough to ensure that the unit can switch to
cooling mode on a warm spring day*.
*When domestic hot water is needed, the heat pump will run at a higher level, and cannot
simultaneously perform active cooling during that period. However, it will open bypass damper if
cooling is required.
If cooling is to have a higher priority than hot water, the unit will cool the supply air and store the heat
in the hot water tank during that period. The hot domestic water will be heated, but not as quickly as
usual in hot water production.

Ventilation at times of low outdoor air temperature
It is possible to prevent low humidity in the home by reducing ventilation in case of low outdoor
temperatures. This function is particularly useful in countries with heavy frosts and at high altitudes
where the outdoor air is very dry.
The function can also be used if no after-heating element has been fitted, and the supply air feels too
cold in case of low outdoor air temperature. Lower ventilation levels will increase temperature
efficiency and thus raise the supply air temperature slightly.
The Compact P heat pump is able to heat supply air up to 34 °C in periods where no domestic hot water
is produced.
