Exhaust air module
function
An exhaust air module uses the heat that is in the
building's ventilation air to heat up the house. The con-
version of the ventilation air's energy to residential
heating is done in three different circuits. From the
outgoing ventilation air (1), free heating energy is re-
trieved from the house and transported to the exhaust
air module. The exhaust air module increases the re-
trieved heat's low temperature to a high temperature
in the refrigerant circuit, (2). The heat is distributed
around the building in the heating medium circuit (3).
Ventilation air
The hot air is transferred from the rooms to the heat pump
via the exhaust air module.
A
The fan then routes the air to the exhaust air module's
evaporator. Here, the air releases the thermal energy to
the brine and the air's temperature drops significantly. The
cold air is then blown out of the house.
B
Refrigerant circuit
A liquid, a refrigerant, circulates in a closed system in the
exhaust air module, which also passes the evaporator.
The refrigerant has a very low boiling point. In the evapor-
ator the refrigerant receives the heat energy from the
ventilation air and starts to boil.
C
The gas that is produced during boiling is routed into an
electrically powered compressor. When the gas is com-
pressed, the pressure increases and the gas’s temperature
increases considerably, from approx. 5°C to approx. 80°C.
D
From the compressor, gas is forced into a heat exchanger,
condenser, where it releases heat energy to the heating
system in the house, whereupon the gas is cooled and
condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an
expansion valve, where the pressure drops so that the
refrigerant returns to its original temperature. The refriger-
ant has now completed a full cycle. It is routed to the
evaporator again and the process is repeated.
F
Heat medium circuit
The heat energy that the refrigerant produces in the con-
denser is retrieved by the climate system's water, heating
medium, which is heated to 55 °C (supply temperature).
G
Ventilation
The hot air is transferred from the rooms to the heat pump
via the exhaust air module.
J
The fan then routes the air to the exhaust air module heat
exchanger. Here, the air releases the heating energy to
the brine and the air's temperature drops significantly. The
cold air is then blown out of the house.
K
The temperatures are only examples and may vary between different installations and time of year.

Maintenance of S135
REGULAR CHECKS
Your exhaust air module requires minimal maintenance
after commissioning. However, it is recommended that
you check your installation regularly.
If anything unusual occurs, messages about the malfunc-
tion appear on the indoor module’s display in the form
of various alarm texts.
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 S135's air filter regularly, how often depends
on the amount of dust in the ventilation air. Select what
is most suitable for your installation.
1. Cut the power to the exhaust air module.
2. Pull out the filter cassette.
3. Remove the filter and shake/vacuum it clean.
4. Check the condition of the filter.
5. Carry out assembly in reverse order.
Even if the filter appears clean, dirt collects in it and this
affects the efficiency of the filter. Therefore, replace it
after 1 years. New filters can be ordered via the installer.
NOTE
Water or other liquids must not be used for
cleaning.

In most cases, the indoor module notes operational in-
terference (operational interference can lead to disturb-
ance in comfort) and indicates this with alarms and
shows action instructions in the display.
If the operational interference is not shown in the display
the following tips can be used:
BASIC ACTIONS
Start by checking the following items:
• That the feed cable is connected to S135.
• Group and main fuses of the accommodation.
• The property's earth circuit breaker.
LOW OR A LACK OF VENTILATION (EXHAUST
AIR INSTALLATION)
• Filter blocked.
– Clean or replace filter (see page 7).
• The ventilation is not adjusted.
– Order ventilation adjustment.
• Exhaust air device blocked or throttled down too
much.
– Check and clean the exhaust air devices.
• Fan speed in reduced mode.
– Enter menu 1.2.1 and select "normal".
LOUD OR DISTURBING VENTILATION
(EXHAUST AIR INSTALLATION)
• Filter blocked.
– Clean or replace filter (see page 7).
• The ventilation is not adjusted.
– Order ventilation adjustment.
• Fan speed in forced mode.
– Enter menu 1.2.1 and select "normal".
GURGLING SOUND
• Not enough water in the water seal.
– Refill the water seal with water.
• Choked water seal.
– Check and adjust the condensation water hose.
