• Before maintenance work the HERU unit must be
currentless. If there is a need of changing or complement any electrical components, it should be
done by a qualified person.
• The HERU unit includes rotating parts that could
cause serious danger on the occasion of contact.
This is why the unit must be duct connected and
the lid closed with the screws tightened, before
starting up the unit.
• After the current is cut for service and maintenance the electric heater may still be warm.
• Make sure that the access cable is not damage at
mounting and installation.
• The HERU S needs a permanent electrical supply.
The unit must be connected via a safety switch.
Any electrical connections must be made by a qualified electrician.

age, always check so the unit is starting up again.
• HERU S is supplied for right handing application, see picture below. If the unit is installed left
handed, and no electrical heater is fitted, changes
can be made in the ”Service Menu” and in the submenu ”Flow Direction”. See page 20.
Carefully read through the manual before starting
up the unit.
• Important when adjusting the flow: Go to Service
Menu (password 1199), choose “AC-motor setup”.
This disable functions such as Summer cooling or
Boost during flow adjustment. The preset fan
speed is standard. See page 11.
When adjusting the airflow of AC-fans there is a
possibility to change the voltage for the different
fan speeds via the separate transformers for supply
resp. exhaust fan. Normal operation should be
done in standard mode. HERU 14 S/19 S has 5step transformers and HERU 35 S/52 S has 7-step.
See wiring diagrams on pages 36-37.
Note! When ajusting fan speed manully, make
sure that the speed keeps the sequences.

in the supply air duct. See page 7 and 36-37. GT7
is connected at the relay card. The temperature
sensor GT7 is placed in the control cabinet when
delivered.
• The antenna should be mounted outside the unit.
The antenna for HERU S is delivered connected,
is placed in the control cabinet.
Note! The antenna should not be mounted against
any metal area or metal items as this will shield
the signal.
The antenna should be mounted as central as
possible. This to achieve the best signal all over
the house. If neede an extension cord is available
as an accessorie.
• All HERU can be fitted with a built-in electric
heater. Choose heater ”On/Off” according to the
instruction on page 18.

R E G U L AT E T H E T E M P E R AT U R E
The air temperature can be regulated either for constant supply air temperature, constant room temperature or constant exhaust air temperature.
For constant room temperature a sensor should be
placed in the room for room regulation (this is also
suitable when a cooling coil is incorporated in the
system).
Exhaust air regulation functions in a similar way
but with the difference being that the sensor is
placed in the extract air duct.
FA N C A PA C I T Y
Airflow (fan speed) is regulated via the week timer
that can be programmed for specific time points
when the fan speed should change from one speed to
antoher (e.g. home or away setting). A special feature
is that you can pressure compensate when supplementary heating, using an open fire or stove (the
exhaust air fan then drops to a lower speed).
The wireless control unit can also manually adjust
the fan speed and even boost the airflow for an indicated length of time. The fan speed can also be controlled by a carbon dioxide (CO2) and humidity
(RH) sensor so that the unit gives a higher airflow
(boost) when the maximum limit value is reached.
The temperature can be regulated in 5 sequences:
1.Cooling recovery + After cooling: The regulation
unit can control a cooling coil (e.g. cooling water
from bedrock), when the cooling recovery from
the rotor is not enough.
2.Cooling recovery or regulated fresh air cooling:
The rotary heat exchanger starts if the extract air
temperature is lower than outside temperatur.
Fresh air cooling: The outside temperature is lower
than desired room temperature. The rotor regulate
the supply air temperature.
3.Outside temperature = desired temperature: When
the outside temperature is the same as desired supply air temperature the rotor stops.
4.Heat recovery: The rotary heat exchanger starts to
recover the warmer room temperature.
5.Heat recovery + heat: In climate conditions where
the rotary heat exchanger, in spite of its high efficiency, is not sufficient to reach the desired supply
air temperature, the controller can regulate either
the built-in electric duct heater or a heating coil.
”Summer Cooling” is a function where you can use
the cool outside temperature at night, to cool down
the inside air. The fan speed is boosted when the
ratio between the outside temperature and the
exhaust air temperature is within the programmed
criteria.
Via the wireless control unit the HERU can be put in
an ”Off mode”, which means that the motors for fans
and rotor are ”Off” but the unit is ”Stand by”. If there
is a requirement of totally cut off power, a switch
must be mounted on the mains.
Boosting the airflow for a specified time can be done
via the wireless control, there is also a opportunity to
do that via a timer connected to the ”0” and ”Boost”
connection on the PCB. With the connectors closed
the boost function will be ”On”.

”Modbus” is a function for data communcation. A special wireless control unit is required.
Modbus is available on one RS485 port. The baud rate is set from the wireless control unit. Communication
uses 1 start bit, 8 data bits, one stop bit and no parity.
Enabling Modbus: Modbus is enabled when the relay unit is paired with a ”modbus enabled” wireless control
unit. Normal wireless control units are not ”modbus enabled”.
Disabling Modbus: Modbus is disabled when the relay unit is paired with a normal wireless control unit.
OTHER FUNCTIONS
• Function test of rotor motor.
The rotor runs for three minutes every day at
12.03, if the rotor has not been operate for 24
hours.
• Function test of heating coil valves and cirkulation
pumps.
Once a week (Mondays at 12.09) there is a
maintenance program running in order to secure
functions of valves and pumps.

CLEANING/FILTER CHANGE
• The filters should be change once a year or at
alarm for filter change. When alarm for Filter
Change, this should be done as soon as possible; as
there otherwise is a risk that the adjusted flow is
not obtained.
• Always turn off the electrical supply and ensure
that it cannot be turned on.
• Open the lid by removing the four screws 15 in
every corner. Do not remove the protective plates
that covers the fans and rotor. 16
• The filters are taken out by pulling them straight
out from their fastening strips 4 .
When changing a filter it is also appropriate to
check if the fans are dirty.
• Remove the the fans and rotor\s protective plates
when the fans have stopped and the heater has cooled. 16
• The fans are taken out, after the quick connectors
have been disconnected 1 , removing the screw 2
and pulling it straight out from the unit 3 .
Dismount the motor plate from the fan housing
12
(the outer screws) and lift out the motor with the
fan wheel. If necessary the fan wheel and fan housing are wiped clean with a damp cloth. The interior of the unit housing can be wiped when necessary.
• If necessary the rotor 6
1 can also be dismounted
(see Dismounting).

SS-EN ISO 3741.
FÖRKLARINGAR
Tabellen ovan visar total A-vägd ljudeffektnivå, LwA, samt denna uppdelad i oktavband
i dB(A) (ref 10-12W). I ”Tekniska Data”, återfinns total ljudtrycksnivå, LpA, i dB(A) (ref 20
x 10-6Pa) beräknat på den totala ljudeffektnivån för aggregatljud vid 230 V.
Relationen mellan ljudtryck och ljudeffekt är
D E S I G N AT I O N S
The table above present the total A-weighted sound power level, LwA, as well as in octave bands in dB(A) (ref 10-12W).
In the ”Technical Data”, the total sound pressure, LpA, calculated from the total surrounding sound power level, LwA, at 230 V is presented in dB(A) (ref 20 x 10-6Pa).
The relationen between sound pressure and sound power is
LpA = LwA+ 10 x log
4pr2 AEkv
LpA = LwA+ 10 x log
4pr2 AEkv
där Q är riktningsfaktor, r är avstånd från aggregatet och AEkv är ekvivalent absorbtionsarea. Vid beräkning av LpA har det antagits att Q=2, r=3 m och AEkv=20 m2, vilket ger
att LpA » LwA - 7.
where Q is the propagation factor, r is the distance from the unit and AEkv is the equivalent absorbtion area.
When calculationg the LpA it has been assumed that Q=2, r=3 m and AEkv=20 m2,
which gives LpA » LwA - 7.
