ERS 10 - An excellent choice
ERS 10 is a ventilation heat exchanger with high temperature efficiency
and low energy consumption.
Excellent properties for ERS 10:
■DC fans
Two energy efficient DC fan (Class A) are integrated in the ventilation
heat exchanger.
■Low noise level
The ventilation heat exchanger has a very low noise level.
■Easy to install
The ventilation heat exchanger is easy to install together with a NIBE
heat pump or indoor module. During installation, the ventilation heat
exchanger is connected to the main product, which enables you to read
off the exhaust air module's values from the main product's display.

Ventilation heat exchange function
An ventilation heat exchanger makes use of the heat in the building's
ventilation air to heat up the incoming outdoor air. From the outgoing
ventilation air (1), free heating energy is retrieved from the accommodation
and transported to the heat exchanger. The exchanger (2) transfers the
heat from the indoor air to the incoming outdoor air.
Ventilation air
The hot air is transferred from the rooms to the heat exchanger via the
building's ventilation system using a fan.
A
In the ventilation heat exchanger the air releases heat energy and the air's
temperature drops significantly. The cold air is then blown out of the house.
B
Outdoor air
The outdoor air is transferred to the ventilation heat exchanger via the
house's ventilation system.
C
In the ventilation heat exchanger the air releases the heating energy and
the temperature is raised.
D
A fan blows the heated air into those rooms that have supply air inlets.

Maintenance of ERS 10
Regular checks
Your ventilation heat exchanger requires minimal maintenance after
commissioning. On the other hand, it is recommended that you check
your installation regularly.
If something unusual occurs, messages about the malfunction, in the form
of different alarm texts, appear in the main product display.
NOTE
Always cut the power before opening ERS 10.
Cleaning the ventilation devices
The building’s ventilation devices should be
cleaned regularly with, for example, a small
brush to maintain the correct ventilation.
The device settings must not be changed.
NOTE
If you take down more than one ventilation
device for cleaning, do not mix them up.
Cleaning the air filter
Clean the filters in ERS 10 regularly, how often depends on the amount
of dust in the ventilation air. Test until you find what is most suitable for
your installation. Remember that the efficiency of the installation can be
reduced by a dirty air filter.
You will receive a reminder to clean the filters in the main product's display.
The default setting for the reminder is every three months, however, if the
power to the main product is interrupted the countdown begins again.
1. Switch off the installation using the MCB in the fuse box or the main
switch for the installation.
2. Remove the front hatch by lifting it slightly and then pulling it towards
you.

3. Pull out the filter cassette.
Supply air filter
Exhaust air filter
4. Remove the filters and shake/vacuum them clean or replace both fil-
ters. Water or other liquids must not be used for cleaning.
5. Check that the filters are not damaged.
6. Carry out assembly in reverse order.
Even if the filters appear clean, dirt collects in them and this affects the
efficiency of the filters. Therefore, both the exhaust air and supply air filters
must be replaced annually. New filters can be ordered via the installer.
Supply air filter: F7 = Pollen filter (Fine filter class F7)
Exhaust air filter: G4 = Standard filter (Coarse filter class G4)
NOTE
Use of a vacuum cleaner or compressed air on the filter is not recommen-
ded, as this diminishes the degree of filtration.

house

Check the water lock for condensation water
The water seal is located outside ERS 10. Contact your installer if you are
unsure of where to find it.
The water seal may dry out during the hotter periods of the year when no
condensation is generated. Therefore, before the cold periods of the year,
the condensation water drain must be checked for blockage due to dirt
and filled with water.
Pour approx. one litre of water into the water seal and check that it runs
through unobstructed.
The water seal must not dry out during those months of the year that
condensation is created because, due to the negative pressure in the unit,
air will be sucked into the unit which will then prevent the condensation
water from running off. ERS 10 can produce several litres of condensation
water each day. If the condensation water drain does not function, water
may cause damage inside the house.
Cleaning the heat exchanger
The heat exchanger in ERS 10 must be inspected at regular intervals. Every
other year is recommended. Contact your installer for assistance with
cleaning.

3 Disturbances in comfort
In most cases, the main product notes a malfunction (a malfunction can
lead to disturbance in comfort) and indicates this with alarms and shows
action instructions in the display.
Manage alarm
info / action
reset alarm
aid mode
Low pressure alarm
alarm
In the event of an alarm, some kind of malfunc-
tion has occurred, which is indicated by the
status lamp changing from green continuously
to red continuously. In addition, an alarm bell
appears in the information window.
Alarm
In the event of an alarm with a red status lamp,
a malfunction has occurred that the main
product cannot remedy itself. By turning the control knob and pressing
the OK button, you can see in the display what type of alarm it is and reset
it. You can also choose to set the main product in aid mode.
info / action Here you can read what the alarm means and receive tips
on what you can do to correct the problem that caused the alarm.
reset alarm In most cases it is enough to select "reset alarm" to correct
the problem that caused the alarm. If a green light illuminates after select-
ing "reset alarm" the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the problem that caused
the alarm remains. If the alarm disappears and then returns, contact your
installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
heat pump produces heat and/or hot water despite there being some
kind of problem with the heat pump. This can mean that the heat pump's
compressor is not running. In this case the immersion heater produces
heat and/or hot water.
Problems with ERS 10 do not affect the main product's operation. You
therefore do not need to select ”aid mode" in event of problems with ERS
10.
Caution
Selecting "aid mode” is not the same as correcting the problem that
caused the alarm. The status lamp will therefore continue to be red.
If the alarm does not reset, contact your installer for suitable remedial ac-
tion.

NOTE
Always state the heat pump's and ventilation heat exchanger's serial
numbers when contacting your installer.

5 Glossary
Climate system
The climate system can also be called the heating and/or cooling system.
The building is cooled or heated using radiators, under floor coils or con-
vector fans.
Disturbances in comfort
Disturbances in comfort means unwanted changes in the indoor comfort,
e.g. that the indoor temperature is not at the desired level.
Exhaust air
The air that comes from the exhaust air device in the various rooms of the
accommodation, to ERS 10.
Exhaust air devices
Vents, usually in the ceiling, in the kitchen/bathroom/clothes closet where
the air is drawn in to be forwarded to ERS 10.
Extract air
The air from which the ERS 10 has retrieved heat, and thereby cooled. This
air is blown out of the house.
Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Outdoor air
Air that is drawn into the ERS 10 and heated.
Supply air
The heated air that is blown from ERS 10 and out into the room.
Supply air device
Valves, usually in the ceiling, where the heated supply air is blown out and
aids in heating up the accommodation.
