Technical information
Application
- CERA units are pressure-independent fresh outside air volume control
units (ventilation units) suitable for stacked housing. The units have
been designed particularly for systems with low noise criteria and for
the accurate measurement and control of air volumes courtesy of the
®
.
The CERA unit controls the amount of fresh air supplied to the room
based on the measured CO
2
level and features override options using
switches, all of which save energy. The CERA unit controls the amount
of fresh air supplied to the room based on the measured CO
2
levels
between a factory calibrated minimum and maximum set-point. It will
provide increased air volumes when the ‘cooking’ function or ‘bathroom’
function is activated. When the ‘night’ function is active it will provide

The units take up very little space and are suitable for use in new or
refurbishment projects (renovations/transformation). The units are

01-01-2021 and did replace the EPC calculation. The BENG calculation
is required for applying for a new building environmental permit and

The energy performance of a building is determined with the new

supply and return spigots. The supply and return air run synchronously
with each other and ensure air balance in the apartment. Two versions of
the CERA system are available: the one-zone system (CERA-1) and the
two-zone system (CERA-2).
a specially-designed servo-actuated 3-way valve that directs air to the
main zones & the sub zones depending on the need.
The CERA PLUS system can be connected to several CO
2
sensors for
several bedrooms and/or other rooms. The highest CO
2
value measured
will be used in the air volume calculation. The CERA PLUS system is
available for the CERA-1 (up to 5 sensors) and the CERA-2 (up to 6
sensors).
The units and the system are not suitable for direct connection to
a motorless or motorised kitchen hood.

Installation drawing type NXOJOOB | CERA-1
Remark:
CERA units | type NXOJOOB
Assembly and installation intructions
The CERA units shall be installed with 3 no. bolts/screws according to
the following installation drawing.
Wall plugs and screws are not supplied. Good quality wall plugs and
screws must be used. The weights of the units are mentioned on
page 9 (CERA-1) and page 13 (CERA-2).
The required diagrams are available upon request.
Point of attention:
- High mechanical stresses in the CERA unit casing must be avoided
as these may cause damage to the structure.
- The CERA unit must never be twisted as this could have a negative
impact on the operation of the damper valves.
- Built-in controller components, electronics and measuring tubes
must be accessible at all times; control equipment is mounted on
- A power supply point, wall socket, must be present at the CERA unit.
The unit is standard equipped with a 1.5 meter power cable with
a plug.
- After installation and adjustment, the unit must be fused. (see page 6).
Recommendation:
should take into account the lowest possible resistance in the total duct
system. The system pressure for the operation of the CERA units
should be a minimum of 100-150 Pa. The secondary resistance
(after the CERA unit) should be as low as possible, preferably
<35 Pa.

A central AHU provides fresh air and ensures static pressure in the system. The distribution of air in the home will be determined by
The central AHU unit must function 24/7.
•
In normal operation, the measured CO

By actuating the pulse switches (kitchen/bathroom) with LED feedback, the air volume in the home can be temporarily set to an increased or

13 hours (night/sleep setting), the control sequence will automatically return to normal operation.

•
CERA-1 is also suitable for integration with the bathroom light; the CERA-1 unit will automatically switch to the increased mode after a 5-minute
•
•
CERA-1 PLUS is available for monitoring CO

levels in multiple bedrooms. A
CERA-S-TCO2
CO

sensor can be installed in a total of 4 bedrooms
and the living room. The highest CO
2
value measured will be used in the calculation of the desired air volume.
•
Optionally a humidity sensor can be used in the bathroom/bedroom, which ensures that the CERA unit automatically switches to elevated
increased mode the moment the humidity rises above a preset percentage. As standard for this type CERA-KLH100-HD-R5V sensor a percentage

Performance data
TYPE CERA-2
1. Sound data is determined in a reverberation
room at an independent sound laboratory,
according to ISO 3741 en ISO 5135
standards.
2. Lw/Oct. (re. 1pW) are sound power levels
for discharge and radiated sound. Values
< 17 dB are indicated by “-“.
3. The values for insertion loss L
w
do not
include end reflection.
4. dB(A), NC and NR index values are sound
pressure levels. Sound pressure levels
< 20 are indicated by “--“.
5. The sound pressure levels for discharge
sound include the values for an acoustic
hose in accordance with table 1.
6. Lp values are including a room absorption
of 10 dB/Oct.
7.
∆
p
s
is the static pressure loss in the CERA
sis the static pressure loss in the CERA
s
unit with the damper fully open.
8. Where an “X” is shown in the table,
the unit’s own resistance is > 100 Pa,
which means sound levels at 100 Pa
are not available.
9. For non standard applications and/or
selections please contact our technical staff .

Sequence of operation of the CERA-2 two-zone system (standard model):
•
The CERA-2 unit features two supply connections on the home side and one return duct with built-in air valves to control the air volume.
®
®
®
Type CERA-2 measures the CO
2
content in two
zones (living room and bedroom). A specially-designed, motorised-sided 3-way air valve controls the supply air between the two zones.
•
A central AHU unit provides fresh air and ensures static pressure in the system. The distribution of air in the home will be determined by
•
In normal operation, the measured CO
2
value (living room) will be used to calculate the required air volume between a minimum air volume
2
value
800 ppm, then the air volume will be equal
zones.
•
By actuating the pulse switches (kitchen/bathroom) with LED feedback, the air volume in the home can be temporarily set to an increased or
reduced mode (night/sleep mode).
•
In increased mode, the required air volume will be maximum regardless of the measured CO
2
value; it will be equally (50/50) divided between the
two zones. After 60 minutes, the control sequence will automatically return to the demand-driven CO
2
control.
•

reading. After
13 hours (night/sleep setting), the control sequence will automatically return to normal operation.
•
•
CERA-2 is also suitable for integration with the bathroom light; the CERA-2 unit will automatically switch to the increased mode after a 5-minute
•
•
CERA-2 PLUS is available for monitoring CO
2
levels in multiple bedrooms
.
In total, a maximum of two sensors in the living room zone and four
CERA-S-TCO2
CO
2
value will be used in
calculating the required air volume and how it is divided.
•
Optionally a humidity sensor can be used in the bathroom/bedroom, which ensures that the CERA unit automatically switches to elevated
increased mode the moment the humidity rises above a preset percentage. As standard for this type CERA-KLH100-HD-R5V sensor a percentage
