SPECIALIST PERSONNEL GENERAL
USER
The heat pump combi unit PKOM4has been
designed and manufactured for use in the
field of controlled mechanical aeration and
ventilation with an additional heating and
cooling function for flats and rooms with
a similar purpose such as seminar rooms
and small oces. The heating performance
for the service water heating is designed
for an average hot water demand (draw-o
profile L in compliance with EN 16147).
The heat pump combi unit PKOM4is intend-
ed for installation in residential buildings
or in commercially used objects. It is a
compact ventilation unit with an integrated
heat pump module and is used for the me-
chanical aeration and ventilation of rooms
and their conditioning (heating or cooling).
In the version with a reservoir additionally
the service water is heated and provided.
Designated use extends to a maximum air
air volume flow of 250 m³/h for the supply
and extract air.
The heat pump module, which consists
of two separately working refrigeration
circuits, enabling heating of the service
water with simultaneous heating or of the
supply air.
The supply sections are supplied with
filtered and conditioned fresh air. The
extract air containing humidity and odours
is dissipated from the bathroom, toilet and
kitchen.
The extracted air must be free of aggres-
sive vapours and substances causing wear.
Any other use shall be deemed contrary
to designated use. The manufacturer shall
accept no responsibility for damages
or consequential damages arising from
improper use.
Designated use also includes adherence
to the maintenance work prescribed in the
operating and installation manual.
This unit is not intended for use by persons,
including children, with limited sensory or
mental capacities or lacking experience
and/or knowledge, unless under supervi-
sion or instruction of a person responsible
for their safety. The unit is not suitable for
outdoor installation and may be installed
in suitable and temperature-controlled
interior areas only. The heat pump combi
unit is not suitable for drying and heating
out new buildings.
The heat pump combi unit of the
type PKOM4is not a ready-for-
use product and may only be
commissioned after having been installed
and connected properly in the ventilation
system. Only qualified and instructed
personnel may work on and with the unit.
Persons transporting, installing or working
on the unit must have read and understood
the operating instructions, in particular
Section 5 "Safety".

2.2 REGULATIONS FOR THE OPERATION
WITH FIREPLACES
Local requirements must be taken into con-
sideration by compliance with correspond-
ing standards, laws and directives.
The central ventilation units
with heat recovery may only
be installed in rooms, flats or
utilisation units of a comparable size in
which fireplaces dependent on room air are
installed, if:
• simultaneous operation of room air-de-
pendent fireplaces and the air extraction
unit is prevented by safety devices, or
• the flue gas evacuation of the room
air-dependent fireplace is monitored by
special safety devices.
- In the case of room-air dependent
fireplaces for liquid or gaseous fuels,
activation of the safety device must
lead to the switch-o of the fireplace or
ventilation unit.
- In the case of room-air dependent
fireplaces for solid fuels, activation of the
safety device must lead to the switch-o
of the ventilation unit.
The central ventilation units for the con-
trolled aeration and ventilation of a flat or a
comparable living unit must not be installed
if room air-dependent fireplaces in the
living unit are connected to exhaust gas
systems, which themselves have multiple
connections.
Shut-o device
Normal operation of the ventilation sys-
tems established by means of the central
ventilation units requires the possibility of
shutting potentially available combustion
air ducts as well as exhaust gas systems
o from room air-dependent fireplaces.
In the case of exhaust gas systems of
fireplaces for solid fuels, it must be ensured
that the shut-o device can only be oper-
ated manually. The position of the shut-o
device must be identifiable by the setting
of the operating handle. This specification
is considered as complied with if a shut-o
device against soot is used.
Fire protection requirements
With regard to the fire protection instal-
lation regulations for the set-up of the
ventilation unit, the provisions of national
law, in particular the building regulation
concerning the fire protection requirements
with regard to ventilation systems in the
relevant latest version must be observed.
Due to the heavy load as well as the irreg-
ular operation, the extract air of a kitchen
extractor hood must not be integrated into
the dwelling's ventilation system. Extract
air from such extractor hoods must be con-
ducted separately by means of an exhaust
air pipe over the roof. The supply air must
be provided for separately (e.g. by window
ventilation). If an extractor hood without
the separate provision of supply air is op-
erated, the balance of the air volume in the
dwelling is no longer kept and the proper
function of the dwelling's ventilation system
is no longer ensured (odour diversion, etc.).
Another option is to operate the extractor
hood in recirculation mode.
2.3 PROVISIONS FOR THE OPERATION

7. Product description
One device, 4 benefits:
Ventilating – heating – cooling – hot water
The PKOM4heat pump combi unit unites
these four functions on a footprint of less
than 0.75 m². Controlled ventilation of living
rooms will constantly ensure fresh and
filtered outside air in the rooms and ensure
hygienic exchange of air. The highly ecient
heat recov-ery system is also optionally
available as a design with recovery of was-
te air humidity.
To prevent overly high summer temperatu-
res in the living rooms, heat recov-ery may
also be bypassed during cooler night hours
by means of a bypass flap.
We dierentiate between 2 versions:
• PKOM4classic: Version with household
hot water.
• PKOM4trend: Version without household
hot water
7.1 PKOM4CLASSIC The PKOM4classic heat pump combi unit
is the pre-ferred compact overall solution
for passive house con-struction homes
with up to 130 m² living area. The vol-ume
of household hot water will comfortably
provide for a family of 4 – 5.
A controlled heat pump will in addition con-
dition the supply air, i.e. heated or cooled on
demand.
Another heat pump is used for ecient
provision of household hot water. Both
heat pumps may be oper-ated in parallel to
ensure uninterrupted provision of air and
water.
7.2 PKOM4TREND Household hot water storage and the asso-
ciated heat pump are omitted in the PKOM4
trend unit version. The PKOM4trend heat
pump combi unit is the best alternative to
conventional living room ventilation units.
The supply air into the living rooms will be
cooled and dehumidified during summer,
as needed. The supplied air will be heated
in the colder months.

In principle: "As much ventilation
as required"
Adjustment of air volume requires relevant
expertise and is performed by a specialist
during initial start-up.
If ventilation is too low, poor indoor air
quality or mould formation may result in
living areas.
If ventilation is too high, indoor air may
become too dry - particularly in the colder
months.
The active ventilation level is displayed
by various buttons. The selected ventila-
tion level can be changed by pressing the
button.
The following selection options are avail-
able:
Scheduler
The system runs on the ventilation level
that is currently active in the scheduler.
The scheduler can be programmed in the
[menu] under [settings].
A demand-controlled air volume regula-
tion is carried out in the scheduler of the
ventilation level and with activated CO2and/
or humidity sensors. Sensors available as
accessories. (For details see section 14.6,
page 37 and section 17, pages 55)
O: The system is in standby mode.
Automatic: In automatic mode an automatic
change-over between summer and winter
mode is eected. This depends on the
outdoor air temperature.
The automatic mode is shown in brackets
below the current operating mode.
Summer: In this operating mode
no heating operation with the
heat pump takes place (exception:
frost protection).
An active cooling operation with the heat
pump can be optionally enabled or inhibit-
ed. The service water (hot water) is heated
via the heat pump.
Frost protection: If the room tem-
perature falls below 10 °C or the
outdoor temperature falls below the frost
protection limit, the heat pump switches on
automatically for the purpose of heating.
Winter: In this operation mode
the heat pump generates heat
if required. Cooling operation is
inhibited. The service water (hot water) is
heated via the heat pump.
Vacation: In this operation mode,
the heat pump generates heat.
Cooling operation is inhibited. Hot
water operation is inhibited. A desired room
temperature specially for the period of
absence can be entered. The time of return
can be also set. On the date of return the
program skips back automatically to the
operating mode before the vacation mode,
which was selected last.
Hot water: In this operation mode
only the service water heating is
active. The ventilation unit and the
heat pump for heating and cooling remain
inactive.

is generally activated for this period of time.
If the heat pump is running in cooling oper-
ation, ventilation level 4 is activated. These
minimum air volumes are necessary to
be able to transport the heating or cooling
energy in each case.
There are various configurations and oper-
ating modes that result in your ventilation
unit being operated with air volumes other
than those set. These include:
CO2-controlled regulation (Figure 1)
Acceptable indoor air should not exceed a
CO2 value of 1000 ppm, meaning that active
ventilation should take place every 1 to 2
hours. A living room ventilation unit with
CO2concentration-based control (CO2 sen-
sor module available as part of the acces-
sories) automatically ensures that a defined
CO2 value of 1000 ppm is not exceeded.
Humidity-controlled regulation (Figure 2)
The relative humidity is a factor that also
contributes significantly to a comforta-
ble living climate. Acceptable humidity is
defined by a comfort window.
When humidity regulation is activated, the
air volume flow is reduced below a relative
room humidity of 35 % and increased above
a relative room humidity of 60 % (see Sec-
tion 14.3, page 37).

Depending on the setting, regulation is
based on the room air or extract air tem-
perature, the desired temperature can be
entered via the control unit.
Scheduler
When the scheduler is activated, a change-
over between normal and operation and re-
duced operation takes place. The scheduler
can be programmed in the [menu] under
[settings].
Normal mode
Here, the setpoint temperature for the ven-
tilation and heating mode is entered.
Lowered mode
Here, an additional setpoint temperature for
the ventilation and heating mode is entered.
Only possible in connection with the activat-
ed scheduler.
Cooling mode
Setpoint temperature for cooling operation.
If cooling is enabled by the user, a setpoint
for the active supply air cooling via the heat
pump can be entered.
Cooling enabled
Here, an active supply air cooling via the
heat pump can be enabled or inhibited. In
addition to a permanent cooling activation
also the possibility of only enabling this
activation during ECO mode is provided.
Control
Here it is defined whether the temperature
is to be regulated via the extract air sensor
integrated into the heat pump combi unit or
via a room sensor.
Room sensor
In the case of regulation via a room sensor
this sensor can be specified in greater de-
tail. Sensors integrated into the control unit
or a separate room sensor are provided for
selection (see accessories page 56).
In the case of regulation via
the room sensor, adjacent heat
sources or direct solar radiation may have
undesired impacts on the control behaviour.
Heating circuit
If the additional function of a heating circuit
is executed (see Section 14.3, page 35), here
the desired room setpoint can be entered.
