2. Product information
2.1. Product description
Living comfort and energy savings are becoming
increasingly important in housing construction.
Nowadays, homes are becoming increasingly better
insulated. Unfortunately, good insulation often comes at
the expense of the indoor climate. Without good
ventilation, moisture, moulds and dust mites can escape
and the air in the house can quickly feel 'stuffy' due to an
increasing concentration of CO2 (carbon dioxide). Itho
Daalderop develops equipment that regulates the indoor
climate and takes into account the requirements for
comfort and energy consumption in homes.
One of these devices is the Itho Daalderop ventilation
unit CVE-S ECO.
The CVE-S ECO ventilation unit is used in individually
controllable ventilation systems based on decentralised,
natural air supply in the facade and central, mechanical
air extraction in the wet rooms.
The CVE-S ECO ventilates several rooms in the house.
Through channels, the kitchen, bathroom, toilet and, if
necessary, the storage/storage room can be accessed.
laundry room connected to the unit for air extraction. A
motorless extractor hood can be part of the system.
To ensure good air distribution, extraction valves are
fitted to the openings of the ventilation ducts in the rooms
to be ventilated. Air is extracted via these extraction
points, while fresh air flows in from outside to inside via
air supply openings (e.g. grilles) in the façades of living
rooms and bedrooms.
The CVE-S ECO is now also equipped with a built-in
humidity sensor as standard. Thanks to its smart control,
this humidity sensor accurately measures the air humidity
and automatically adjusts the ventilation accordingly.
When the sensor detects an (abrupt) rise, the automatic
control will speed up the ventilation unit to the maximum
position. The RH sensor cannot be adjusted (without
special Itho Daalderop tools).
In this way, the unit helps to reduce the humidity in your
bathroom, refresh the toilet and eliminate cooking odours
from the kitchen.

3. Installation
3.1. Installing the ventilation unit
Attach the ventilation unit, preferably in a closed room,
with the appropriate screws and the mounting holes to a
(sloping) wall or ceiling/floor with sufficient load-bearing
capacity (> 200 kg/m2). (A)
The ventilation unit is equipped with five air outlets: one
outlet for the extraction of air to the outside and four
outlets for the extraction of exhaust air from the house. (B)
a) Connect the outlet spigot (1, diameter 124 mm) to
the exhaust duct / roof outlet to the outside.
b) Connect the suction nozzles (1-4, diameter 124
mm) to the ducts leading to the rooms to be
evacuated.
c) Close unused spouts on the unit with the
blue caps provided.

A
ä Warning!
When the unit is used in a stacked construction, a
mechanical non-return damper must be fitted in the
discharge duct to prevent backflow from the central
duct.
