2 Hints for the operator and the qualified personnel
Product description
The CLIMOS is a ventilation device with heat recovery for healthy, balanced and energy-saving comfort ventilation. A
comfort ventilation system consists in exhausting stale, odorous air for example from the kitchen, the bathroom,
W.C.s and in introducing an equal quantity of fresh air into living rooms, bedrooms and children’s rooms.
For heat recovery, the CLIMOS is equipped with a membrane moisture heat exchanger (enthalpy exchanger) which,
due to its physical properties, is not only able to transfer heat, but also moisture. The use of moisture sensors for limit
monitoring in rooms with high humidity rise is recommended. The casing is made of powder-coated sheet metal with
anthracite colouring. The internal lining made of high-quality polypropylene provides the necessary heat insulation
and device noise protection.
The CLIMOS is equipped with an integrated defroster heater. The design of layout air connection is available in the
construction types A or B. Amongst others, the type plate informs about the construction types.
The CLIMOS includes two maintenance-free 230 Vac radial fans with the integrated power supply unit and electronic
commutation. The volume flow constant fans keep the air quantity at a constant speed for each selected fan rotary
speed. The air quantity is also not affected by soiled filters.
By default, a filter in class ISO Coarse ≥70 % (M5) is used in the unit for the outdoor air and the extract air. As an
option, filters in class ISO ePM1 ≥60 % (F7) can be used for the outdoor air.
They consist of a synthetic woven filter medium with a frame made of polypropylene.

Type plate
The type plate clearly identifies the product. The information on the type plate is necessary for the safe use of the
product and in case of service-related questions. The type plate is located on the side of the casing next to the
electrical connections. The type plate must be permanently attached to the product.
Frost protection
The CLIMOS is equipped with an automatic frost protection which prevents the heat exchanger from freezing at a too
low outside temperature. If the outside air temperature limit at the device falls below the threshold value a PTC heater
battery is activated. If the heat emission of the PTC heater battery is not sufficient enough, the fans will be
temporarily switched off when the treshold value is exceeded.
Monitoring of the supply air temperature for frost protection of an optional hydraulic heater battery
downstream is not available!

Joint operation with heat-producing appliances
In case of simultaneous operation with heat-producing appliances, e.g. chimneys, the corresponding standards and
regulations must be complied with by the qualified personnel. The joint operation of indoor air-dependant heat-
producing appliances and ventilation plants requires an appropriate safety device (differential pressure switch) or a
plant-specific measure, in the event that dangerous negative pressures can be generated in the installation room of
the heat-producing appliance during operation.
Available control modules
The CLIMOS can be equipped with the following control panels:
•External control panel (W x H x D in mm: 71 x 71 x 25)
•External control signal (0-10 V)
•External boost ventilation switch (any number, potential-free)
External control panel
The operating panel is equipped with a rotary knob for stepless control of the ventilators with a 9-step scaling for the
air volume flow. The two ON/OFF buttons are used to select the operating mode. Either normal mode (both
ventilators on), or extract air (only exhaust air ventilator on) or supply air mode (only supply air fan on) can be
selected. The selected operating mode is indicated by green a LED of the respective symbol. The operating functions
are carried out with the button boost ventilation mode / reset filter runtime. The fan-symbol with the red LED signals
the respective operating mode depending on the function.

Button boost ventilation
mode / reset filter runtime
Function-button for boost ventilation mode:
Pushing this button activates the boost ventilation with an air volume flow for the
duration of 15 min which corresponds to position 9 of the rotary knob. After the boost
ventilation time of 15 min is over, the air-flow returns to the previously suppled air
quantity in the respectively active operating mode. The boost ventilation mode can be
terminated any time by pushing this button > 3 seconds.
Function button for reset filter runtime:
An operating hour counter with a set runtime of 180 d is integrated in the control for
cyclical filter control. The button boost ventilation mode / reset filter runtime is used to
reset the filter runtime. Pushing this button > 3 s restarts the filter runtime.
If a reset of the filter runtime is carried out before expiration of the 180 d by pushing
the button > 3 s, the reset is acknowledged by 4x quick flashing of the LED-fan-
symbol.
No reset command is possible during an active boost ventilation mode!

Tab. 3: Function assignment of LED-signalling
External control signal 0-10V
The ventilation device can be operated with an external control signal 0-10 V. A 0-10 V applied analogue signal is
interpreted as control signal for the fan rotational speed. The externally suppled control voltage is only valid above
the range of the present scale position of the rotary knob.
In order to use the whole external 0-10 V – control range, the rotary knob must be in position 1!
Boost ventilation mode with external boost ventilation sensing device
In most cases, boost ventilation sensing devices are mounted in exhaust air rooms such as bathrooms, W.C.s or
kitchens in order to activate temporary maximum ventilation in these rooms for fast discharge of increased moisture
and odours.
When operating this control element, the functional properties and visualisations described for the boost ventilation
mode are generated. The boost ventilation mode is started again at each activation and interrupts the current
operating mode for the duration set. Following this, the device switches back to the previously active operating mode.

11
Maintenance by the operator
Maintenance of the ventilation device and plant by the operator is limited to the periodic change of the filters and
cleaning of the supply and extract air valves. The filter must be checked every 3 months and changed if necessary,
however, at least every 6 months.
In this context, also check other filters available inside the ventilation plant and change them if necessary. A
replacement or cleaning of the filter mats at the extract air valves (e.g. bathroom, kitchen, W.C.s) should be carried
out every 2 – 3 months or at your own discretion when checking the degree of soiling.
If maintenance work is not carried out regularly, this impairs the functioning of the comfort
ventilation in the long term!
Replacement of the filter
The plant must not be operated without filter. During filter replacement and maintenance work, the
ventilation device must be switched off!
Two high-quality original filters of the manufacturer are installed inside the CLIMOS. After the corresponding
message of the control panel or after visualisation of a programmed digital output signal, the filters in the CLIMOS
shall be checked. In order to do so, proceed as follows:
1. Switch the device to standby mode or disconnect it from the power supply.
2. If applicable, pull the red design filter cover Aout of the casing cover’s holder.
3. Grasp into the recessed grip B of the filter compartment.
Perhaps the EPP-filter covers are very tight during the first filter change. Using a blunt
object (e.g., the handle of a spoon) the EPP-filter cover can be levered.

Reset of filter runtime
After a filter change the counter for the filter runtime has to be reset. The reset is carried out by pushing the button
boost ventilation mode / reset filter runtime > 3 s. The quick flashing cycle of the LED in the filter-symbol is ended.
All maintenance work performed must be documented in check list A!
What to do in the event of a failure?
Please contact the installer immediately in the event of a failure. Make a note of the error display and the failure code
respectively. Also note down the type of your CLIMOS, for that purpose, see type plate on the side of the device.
The mains connection must always be available, unless the CLIMOS must be put out of operation due to a serious
failure, maintenance work or for other imperative reasons.
As soon as a power disconnection has been performed, the living space is not mechanically
ventilated anymore. This may cause moisture and mould problems in the living space. Therefore,
the long-term shutdown of the CLIMOS has to be avoided!
For the period of absence, the plant should be operated at the lowest fan speed or in the un-
occupied mode!
Disposal
When the life time cycle of your CLIMOS has expired, the company PAUL Wärmerückgewinnung GmbH offers you
free take-back. If you do not make use of the possibility of feedback of recyclable product parts into the cycle of
materials, we would like to remind you that the CLIMOS must not be disposed of in the normal household garbage.
For this kind of disposal, please obtain information on the possibilities of reuse of components or the eco-friendly
treatment of the materials from you community.

Mounting Preparations
At first, mount at the long sides of the CLIMOS 2 pieces of the provided mounting brackets each with 4 cross-head
screw each.
Fig 9: Mounting brackets
At first, check the necessary load capacity of the respective fixing surface (own weight of the CLIMOS is 30 kg) and
the secure fixing possibility using the mounting brackets. If the fixing is made at a wooden or lightweight construction,
we recommend the die insertion of a vibration-damping distance washer for each mounting bracket.
Mounting position ceiling-hanging
In case of the mounting position ceiling-hanging, the mounting is made horizontally at the ceiling surface in the
slotted holes (38x10 mm) of the 4 mounting brackets with suitable fixing elements depending on the ceiling
construction.
If the CLIMOS is to be mounted in an intermediate ceiling, we recommend the use of the product-related drywall
inspection flap in the suspended ceiling. The distance between the lower edge of the raw ceiling and the lower edge

15
of the drywall inspection flap is at least 270 mm. In this case, the ventilation device is fixed centrically in the opening
space of this maintenance flap at the raw ceiling.

Air duct connection
When mounting the air ducts, the following points must be taken into account:
•Mount the types of air ducts of the ventilation plant to the connection stubs according to the present
construction form R (right - type A) or L (left - type B), see label air ducts next to the type plate.
Fig 16: Arrangement of air ducts depending on construction type – right (type A) or left (type B )
•Remove the caps of the air connection sockets
•Use air duct material with air resistance as low as possible, and connect the ventilation components air-tight
among each other
•The connection stubs of the device are made of EPP and have sleeve dimensions DN 125
•The outdoor air and exhaust air ducts must be insulated in such a way that they are vapour-diffusion tight
•In the event that a low point is unavoidable when installing the exhaust air duct from the device’s exhaust air
stub to the exhaust air outlet, a connection for condensate drain must be provided at that point
•A straight pipe routing of the exhaust air from the device connection stub to the roof hood should be avoided,
since during defrosting of possible ice formations, they might fall onto the blades of the exhaust air fan and
cause damage to these blades
Fig 17: Arrangement drainage of the outdoor air duct and exhaust air duct
•If a silencer is provided at the exhaust air stub, it must be guided upwards by means of a bend in order to
protect it against drenching caused by condensate returning from the exhaust air duct.
•If the exhaust air is guided over the roof, this guidance must be equipped with a double-wall or insulated roof
lead-through. Thus, condensate formation between the roof boards is prevented.

•For the supply and extract air ducts, we recommend a thermal and vapour resistant insulation in order to avoid
unnecessary temperature loss both in summer and winter.
Electrical connections
Electrical connections must be established in accordance with the applied standards to electrical
equipment and only by qualified personnel!
The electrical power supply of the CLIMOS is provided via the 3-pole plug connection Aof a lower power device by
means of the power cable. The cable to the control panel is connected to control board of the device. To do this the
