Heat pump domestic hot water
CAUTION
Avoid direct contact with the heating system pipes in the heat pump as they can get very hot.
CAUTION
To protect the heat pump against damage, it is fitted with the following safety equipment:
• Electronic temperature monitoring
The heat pump must undergo suitable service inspections under applicable legislation and regulations
to keep it in good condition and in compliance with safety and environmental requirements.
Responsibility for maintenance of the heat pump rests with the owner/user.
Disposal
Ventilation unit
Nilan’s units consist mainly of recyclable materials. They must, therefore, not be
mixed with household waste, but must be delivered to your local recycling center
for disposal.
Heatpump
Concerning disposal of units with heat pumps, it is important to contact the local
authorities for information about correct handling of these. The heatpump
contains the refrigerant R134a, which is harmful to the environment if not
handled correctly.

Emergency stop ventilation
I
f the ventilation has been stopped for a lengthy period, condensation will occur in the duct system.
This occurs when the warm air in the dwelling penetrates into the cool ducts. This presents the risk that
the water will drip out of the ceiling valves, damaging floors and furniture.
To avoid this, the user is not directly permitted to turn off the ventilation. However in emergency
situations, where the user is asked to go indoors, close windows and doors and turn off ventilation
systems, this must still be possible.
The user may then press the emergency stop in the settings menu:
A warning will appear before the ventilation can be turned off:
Warning: Are you sure you wish to turn off the ventilation?
If the ventilation is not running, you may get problems with high air humidity and condensation in the
ventilation ducts, and a risk that your home may be damaged.
You are only turning off the ventilation. Domestic hot water will be heated by the supplementary
electric heating, if activated.

User and installer rights
n the setting menu both user, installer and factory settings are shown.
I
• 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
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.

Service and Maintanance
Maintenance
Regular maintenance
Y
our Nilan ventilation unit will last for many years if it is correctly maintained. Correct maintenance
will also ensure that the unit runs optimally at all times with low energy consumption.
In the following we point out the regular maintenance which you can perform yourself and the annual
service which should be carried out by a professional.
External cleaning
The ventilation unit
The outside of the unit can be cleaned with a mild soap solution.
The ceiling valves
Over time a ring may develop round the inlet valves. This is a natural process and is due to dust in the
room air, not to defective filters or failure to change filters.
As very few painted ceilings are washable, you are recommended to vacuum round the valve and then
wipe the area with a damp cloth.
It is a good idea to dismantle and clean the valves when necessary. The valves have been set by the
installer for a specific airflow, so it is important not to rotate them, as this will change the setting and
unbalance the ventilation system.
Changing the filters.
The filters are there to protect the fans and heat exchanger by preventing them from being coated by
dust and dirt.
For optimum operation it is important to change the filters before they become clogged. In normal
operation, G4 filters from Nilan should be changed every three months. In newbuild, it is recommended
that the filters are changed when the house is first occupied, as they may be clogged with building dust.
If the filters are not changed regularly, this will hamper ventilation, reducing the indoor air quality,
using more power than necessary, and producing insufficient domestic hot water.

unit with the filter pad facing upwards.
8. Reset the alarm:
Reset the alarm on the control panel in the "Filter
settings" menu under Ventilation.
13
Water trap
If the water trap in the condensate outlet dries out, air will blow into the unit. This will prevent the
condensate water from draining away. Instead it will accumulate in the condensate tray. When there is
no space left in the condensate tray, it will spill over, possibly causing water damage on the floor.
ATTENTION
The water trap must be checked at regular intervals and filled with water. This is done by filling
the condensate tray with water and checking that it runs out.
Safety valves
The safety valve for the domestic hot water is prominently connected to the drain by the installer. It is
important to check regularly that it is not dripping from the valve.
If it is dripping, contact a plumber to remedy the matter.

Service
A
nnual service
It is important to perform an annual service on the unit to ensure it will continue to perform optimally
with low energy consumption and long service life.
You are recommended to take out a service agreement with the installer, as certain elements of the
service require an authorised technician.
Visual inspection
You are recommended to carry out a visual inspection of the whole unit.
Check that there are no sweating pipes to cause condensation and damage the substrate on which the
unit stands.
Check that there are no cracks in hoses and pipes and no leaks in the heat pump and hot water tank.
Check that there are no damaging accumulations of dirt in the unit.
Checking the sacrificial anode
An electrically monitored anode has been mounted for protecting the hot water tank. When it is time to
change the anode, a warning will appear on the control panel display.
Check the sacrificial anode to ensure that the electrical monitoring is undamaged.
Checking the safety valve
The safety valve for the domestic hot water should have an annual function check to ensure it is
functional at all times.
The function check must be carried out by a trained plumber.
Internal cleaning
For hygienic reasons, it is important that the unit undergoes annual internal cleaning. This will prevent
the formation of fungus and bacteria which impair the internal air quality.
• Wipe down the internal plate parts and pipes with a damp cloth and a mild soap solution.
• Check and clean the evaporator coil.
• Check and clean the counterflow heat exchanger. If necessary, it may be removed and rinsed with a
shower head.
• Clean the condensate trays with a damp cloth and a mild soap solution.
• Check the condensate outlet to make sure the water can exit freely.
Check the air intake and outlet
It is important for operation of the unit that air can freely move through the air intake and outlet.
If roof stacks have been fitted to the air intake and outlet, check that they are not blocked with birds'
nests, leaves or other dirt which can hamper air passage.
If, instead of roof stacks, grilles have been mounted in facades or eaves, check that they are not
clogged with leaves or dirt. Grilles are particularly likely to become clogged.
15
Check ventilation ducts
t is important for operation of the unit that there is free air passage through the ventilation ducts.
I
After some years of operation, dirt will attach itself to ventilation ducts or tubes, and accumulations
may lead to higher pressure drop in the ducts, leading to higher power consumption. It is therefore
important to clean out the ducts when too much dirt has collected.
After attending to the inlet and outlet valves, it will be advisable to have them adjusted again, to
ensure optimum operation of the ventilation system.
However, it will not be necessary to clean ducts more than every few years.
The heat pump
The heat pump must be inspected in accordance with applicable laws and regulations, such that it is
kept in good condition and meets safety and environmental requirements.
The installer is obliged to inform the owner/user about applicable laws and regulations.

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

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.

Humidity control
he unit has a built-in humidity control to control the ventilation relative to the average humidity, in
T
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.

Settings active cooling
epending on architecture, the dwelling may require cooling in the summer. Compact P has an integral
D
heat pump, primarily used for production of domestic hot water. The heat pump has a reversible
cooling cycle, and in summer is able to cool the supply air, while still producing domestic hot water.
Thus, in principle, this gives "free" domestic hot water heating.
The heat pump is able to cool the supply air by up to 10 °C and, in order to make it as efficient as
possible, it is a good idea to turn up the ventilation when cooling is required.
However, it must be emphasised that it does not function like a conventional air conditioning unit.
Instead, by cooling the supply air, the indoor air is dehumidified, thus giving a pleasant indoor climate
even when indoor temperatures are high.

*When domestic hot water is needed, the heat pump will run at a higher level, and cannot
imultaneously perform active cooling during that period. However, it will open the bypass damper if
s
cooling is required.
By choosing cooling 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 domestic hot water will be heated, but not as
quickly as usual in normal domestic hot water production.

Ventilation at times of low outdoor air temperature
t is possible to prevent low humidity in the home by reducing ventilation in case of low outdoor
I
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.

HW standby function
It is possible to set the hot water production on standby for a period between 1 and 180 days. In this
way, energy for heating the domestic hot water can be saved when on vacation, or the holiday cabin is
closed for the winter.
The ventilation section continues operation at the set values.

On activating the frost protection, supplementary
electric heating is switched on at a tank temperature
˂ 4 °C (T11 or T12) and turns off again at a tank
temperature ˃ 6 °C (T11 and T12).
Frost protection will work even if supplementary

Here the temperature is indicated to which the
supplementary electric heating will help to heat up
the domestic hot water. It is controlled by the T11
temperature sensor at the top.
For instance, if many guests are staying in the
weekend, it may be beneficial to turn up the
supplementary electric heating to ensure sufficient
hot water for showers.
NB! Requires the supplement electrical heater to be
activated.
40 ↔ 80 °C
60 °C
This setting will operate independently of the set
point for the hot water.
When Compact P for example, ventilates with active
cooling, the heat is deposited in the hot water tank.
The temperature in the hot water tank may thus
increase up to 80 °C.
If no anti-scald device is fitted under the tank, this
setting must not be set higher that 65 °C, to avoid
scalding.
If an anti-scald device is fitted under the tank, it will
be advisable to change the setting to 80 °C, to
increase the cooling capacity.

Emergency operation
Emergency operation domestic hot water
If an error occurs in the controller or components in the Compact P, and the unit therefore stops, it will
not be able to produce domestic hot water.
If the installer is not able to come right away or the error happens outside the opening hours, and you
therefore cannot contact the installer, there is a possibility to get hot water by setting the unit into
emergency mode.
The button for the emergency operation are located behind the large door
The emergency operation has three settings:
I - Auto: El-supplementation is controlled by the control in the unit
(standard setting)
0 - Off: El-supplementation is off and cannot be turned on again by
the control in the unit
II - Manuel: El-supplementation is turned on, and cannot be turned
off by the control in the unit (Don´t turn it on if there is no water in
the tank)
CAUTION
In manual operation, the water temperature can achieve 75 °C, which can cause scalding, if you
are not careful when you open the hot water.
