Ventilations is a pure necessity. Unfortunately some people
tend to forget! Insufficient ventilation can cause serious
damage in a building. Fungi and woodrot can cause
permanent deterioration of the construction (In the
Netherlands alone, this type of damage accounts for many
tenths of millions of Euro).
Allergenic and hazardous substances in too high
concentrations-- are perhaps an even more serious threat
with severe consequences for your health.
Ergo, you can never have enough fresh air. But there is a
snag. Ventilation also requires energy, not only to run the
fans but especially because fresh air is also cold air that
needs to be heated to room temperature. In modern
buildings these so-called 'ventilation losses' may account to
as much as 50% of the total heating costs. Because of this,
modern or refurbished houses are usually as air-tight as
possible and the inhabitants are stuck with a dilemma:
“How do I get a good indoor air quality without wasting
energy?
ClimaRad is your answer! It provides healthy ventilation
and it saves energy.
CO , Indoor Air Quality and ClimaRad
2
People produce CO and humidity through breathing. In
2
occupied, badly vented rooms the CO -concentration will
2
increase rapidly. High concentrations of CO are not
2
damaging on the short term, but they create a damp and
smelly indoor climate. If people stay in such a climate for a
Why ClimaRad ventilation?
longer period it may irritate eyes, throat and nose. Also,
most obvious at work or school, higher CO concentrations
2
are known to affect the ability to concentrate.
Apart from that, CO is an important indicator for the
2
presence of other hazardous substances (VOCs, solvents,
formaldehyde, radon, fine dust particles, etc.) that can be
detrimental to your health. In other words, a CO concen-
2
tration below certain threshold values usually guarantees a
good indoor air quality overall.
The table below shows threshold values for CO2
concentration that are used in practice.
Desired CO -concentrations indoor climate:
2
Nominal : 1200 ppm CO2
80% satisfied : 1000 ppm CO2
People with respiratory
problems : 800 ppm CO2
The ClimaRad Sensotronic features a CO sensor that
2
measures the CO level and automatically adjusts the fan
2
speed to maintain the desired level. Thus the ClimaRad
always provides the adequate ventilation.
Humidity and ClimaRad
Every day several litres of condense and humidity are
released in a house because of the presence of people and
certain activities like cooking, washing and cleaning. Apart
from that, in new homes, humidity may stem from the
building construction.
Mites, fungi and rot thrive on a high humidity level in the
house. The mites and fungi can cause allergies and wood
rot can be detrimental to the building construction.
Adequate ventilation can prevent high humidity. The
ClimaRad has a humidity sensor that will react to high
humidity levels and try to lower it in an intelligent way. For
instance, if in (rare) cases the absolute outdoor humidity is
higher, no extra ventilation will occur.
Outside Air and ClimaRad
Depending on where you live, outdoor air may be polluted
with allergenics (pollen), exhaust fumes (benzene), lead
and fine dust particles. Obviously these substances are not
desired indoors.
There are two types of filters available for the intake-duct
of a ClimaRad to remove these substances:
!A fine dust and pollen filter and
!a combi-filter for fine dust with an additional active coal
filter
Energy Use and ClimaRad
By far the most popular way of ventilation is opening
windows and ventilation-grids.
A considerable drawback of this “method” is that it is
unpredictable whether the ventilation is too little,
unnecessary or just enough. On top of that, the warm
indoor air is lost before its heat content (energy) being put
to good use. This energy waste is not only bad for your
wallet, but also for the environment.
ClimaRad has an air-to-air heat exchanger that transfers
the heat of the outgoing air to the ingoing cold air. This
saves a bundle on your heating costs, but also the
ClimaRad is especially equipped to perform its function with
a minimum consumption of electricity. It uses DC fans in
combination with a highly efficient power supply. At a
ventilation rate of 40 m³ per hour the electricity
consumption is as low as 7 W. At 80 m³/h it is a mere 25
W. The stand-by power use (fans-off but sensors still
working) is as low as 1.5W.

The ClimaRad-system is a combined heating and
ventilation-system, especially developed for individual
dwellings in residential and commercial buildings. In every
dwelling the ClimaRad takes care of the indoor climate,
independently of the number of people present. Its very
short intake- and exhaust ducts do not require a complex
air duct network in the home, making it the ideal system to
install and maintain in both new and renovated houses.
The ClimaRad Parts
The ClimaRad-system consists of the following parts:
1 the ClimaRad radiator;
2 the ClimaRad balanced ventilation unit;
3 the ClimaRad mounting frame and radiator-supports;
4 the ClimaRad wall-ducts.
Depending on the configuration you ordered, a control
panel is also part of your ClimaRad.
ClimaRad radiator
The ClimaRad is shipped with a specially developed one- or
two-panel radiator. This radiator is connected to a
conventional CH-system with flexible piping. Once mounted
on its special supports, it can be tilted forward to allow for
easy access to the ClimaRad balanced ventilation unit, e.g.
for cleaning. The control of the ClimRad radiator is identical
to what you are familiar with: a normal or a thermostatic
valve. And should the situation require, there is no problem
to install even motor-valves.

ClimaRad: Energy Saving and Healthy
ClimaRad has solved the dilemma: A healthy indoor climate
and saving energy at the same time is possible.
Any dwelling with at least one outside wall can have an
optimal indoor air quality. You set the desired level of air
quality and the intelligent Sensotronic automatically takes
care of the rest. If you leave the room, the ClimaRad
Sensotronic detects the decreased CO2-level and will
automatically reduce the fanspeed. Even opening a window
doesn't escape the attention of the Sensotronic and it will
cut back the fan-speed without the user having to lift a
finger!
Always a good indoor air quality at the lowest possible
energy bill. That is what the ClimaRad has to offer!

Sensotronic

ClimaRad (balanced) ventilation unit
The ventilation-unit is located behind the radiator and
consists of two maintenance-free DC fans (for air-intake
and exhaust), a plastic heat exchanger, air-filters and an
electronic control-unit; all this in a sturdy plastic housing.
Three types of ClimaRad balanced ventilation units are
available:
!The Sensotronic features CO - and humidity sensors
2
continuously measuring the air quality. The ventilation
rate is PID-controlled on the basis of the desired air
quality level. The user sets the desired air quality level
through the control panel.
!The Slave-Unit has no sensor, no central processing
unit and no control panel en must always receive its
settings from a Sensotronic version.
Air Filters
Every ClimaRad has a HAF (High Air Flow) air filters for the
air-intake and the exhaust air. At the air intake side the
filter cleans the incoming fresh air. Used air from the room
is also passed through a filter to keep the ClimaRad heat
exchanger clean. An light on the control panel indicates
when the air intake filter needs inspection. The filter for the
outgoing air needs some regular cleaning with a vacuum
cleaner from the outside (no need to dismount the filter).
In principle this filter can be replaced. Both the intake and
exhaust filters can be easily exchanged by the user and
require no special tools (see chapter ‘Maintenance’).
Energy Saving
The ClimaRad is a balanced ventilation system with waste
heat recovery. 'Balanced' implies that per time period-- the
amount of air that is extracted from the room equals the
amount of fresh air. Waste heat recovery means that the
heat of the used exhaust air is used as much as possible to
preheat the incoming fresh air. This saves on your energy
costs and prevents cold draughts from the incoming fresh
air.
The automatic control of the ClimaRad Sensotronic also
saves energy, because no unnecessary ventilation occurs.
Finally, the DC fans, the efficient power supply and the low
stand-by consumption contribute to minimal electricity
consumption. (see technical specifications for typical use
data).

Your ClimaRad needs to be installed by a qualified
ClimaRad installer, who also has taken the additional
ClimaRad installation-training. Only in that way, an optimal
operation of your ClimaRad can be guaranteed.
Note: The power cord should only be
replaced by qualified personnel. This product
needs to be connected to a grounded wall
socket (230V, 50 Hz).
Because ClimaRad requires no in-house system of air ducts
it offers unique possibilities for installation.
For instance, in older existing homes and buildings you can
start installing one ClimaRad in a room with critical air
quality (e.g. a children's bedroom) and then expand the
system gradually to other rooms in the house.
Also in new houses and commercial buildings the fact that
you don't need an in-house duct system offers big
advantages like lower installation costs, appropriate
ventilation per room and ease of maintenance.
To optimise the energy saving potential of the ClimaRad it
is recommended to use the ClimaRad units in the rooms
and combine them with discontinuous extraction fans in the
“wet” areas of the house (shower, toilet). 'Discontinuous'
means for instance timer or humidity controlled.
After the installation, the installer is also responsible for
testing en preparation for first use of the ClimaRad.
Instructions for first use
Check if the power supply cord is correctly
connected to a grounded wall socket (230V,
50 Hz)
The control panel allows you to check and alter the
ventilation-settings. Check whether the control panel is
properly connected. The ClimaRad also works without a
control panel, but in that case settings cannot be checked
or altered.
Switching on
You turn on the ClimaRad by switching on the on/off switch
at the left lower bottom of the ventilation unit. The control
panel indicators will light up and the electronics will
perform a self-test during the first seconds.
Note: the ventilation-unit must always remain switched on.
It may only be switched off during servicing and
maintenance.

air quality) and “-“ (allow lower air quality) you can set the
desired air quality.
The scale of the 5 indicator lights on the control panel of
the Sensotronic corresponds to the following CO2
concentrations. (lower CO2 levels mean higher air quality
level).
Control panel
See the illustration of the control panel on the inside cover.
The Sensotronic control panel allows the setting of the
following parameters:
!Desired air quality
!Base ventilation (on/off)
!Pause button (max. 60 minutes fans off)
!Boost button (max. 30 minutes at max. rate)

Boost
If you want to get rid of nasty smells or cigarette smoke,
you can run the ClimaRad fans temporarily on maximum
speed using the boost-button. After 30 minutes the
ClimaRad automatically returns to sensor controlled mode
and vent accordingly.
!Boost 'on': press the boost-
button. The ClimaRad will run both
its fans at maximum speed for 30
minutes
!The default maximum flow rate is
100 m3/h. Using the ‘+’ and ‘-’
buttons you can change this value.
!Boost 'off': press the boost-
button. This will immediately stop
the boost-mode and the unit
returns to the sensor controlled
mode and vent accordingly.
Night Cooling
During the summer months it is often cool in the evening
and at night. You can use this fresh air to cool your house
by using the Night Cooling mode. When this mode is
activated, the ClimaRad compares the inside and outside
temperature and if the outside air is sufficiently colder, the
ClimaRad will blow the cold outside air into your room for 6
hours. No room air is extracted. After 6 hours the ClimaRad
automatically returns to the sensor controlled mode and
vent accordingly. The default factory setting for the
ventilation rate is 100 m3/h. Using the ‘+’ and ‘-’ buttons
you can change this ventilation rate.
!Night Cooling 'on': press the
Cool Air button. The ClimaRad unit
will run both fans for a short while
to measure inside and outside air
temperature. During this
preparatory stage the Cool Air
indicator light will blink. If the
temperature difference is high
enough, the cooling phase will start
and last for 6 hours. If there is not
enough temperature difference the
ClimaRad unit will wait for 15
minutes before doing another
measurement.
!Night Cooling 'off': press the
Cool Air button again. This
immediately ends the Night Cooling
mode.
