The EnviroVent Slimline 150 is a ventilation
unit with heat recovery with a maximum
ventilation capacity of 150 m
3
/h and low-
energy fans.
Slimline 150 Features:
• Steplessly adjustable air ow rates through
a control unit (supplied with appliance).
• Filter indication on the control unit / multiple
switch.
• A completely new intelligent frost
protection system. This ensures that
even at low outdoor temperatures the
appliance’s performance remains optimal
and that, if necessary, it activates the
standard preheater.
• Low sound level
• Comes as standard with automatic bypass
valve
• Constant ow control
• Low energy consumption
• High eciency
Slimline 150 is available in two types:
• Slimline 150
• Slimline 150 Plus
Compared to the Slimline 150, the Slimline
150 Plus has a more extensive control board
which increases the connection options.
These installation instructions describe both
the standard Slimline 150 and the Slimline
150 Plus.
With the aid of the supplied mounting
brackets, the Slimline 150 (Plus) can be
mounted either on the wall or on the ceiling.
For the correct position of the connection
ducts and dimensions see page 6.
When ordering an appliance always state
the correct type; subsequent conversion to
a dierent version is highly labour-intensive.
The Slimline 150 comes ready to wire into
the 230V mains fused spur.
The appliance comes as standard with a
control unit, but connection of a simple
4-way switch is possible as well.
If a 4-way switch is installed instead of a
control unit, the settings of the appliance
can only be changed with a laptop.
Connecting a combination of control unit
and multiple switch is another option.

The appliance is supplied ready to wire into
the fuse spur and operates fully automatically.
The extracted indoor air heats up the fresh,
clean outdoor air. That saves energy and
fresh air is sent to the required rooms.
The control system has four ventilation
modes. The air ow rate can be adjusted
per ventilation mode. The constant volume
control system ensures that the air ow
rate of the supply and extract fans is
always delivered despite any resistance
encountered in the ductwork.
The standard bypass valve makes it possible
to supply fresh outside air that is not heated
by the heat exchanger. Particularly during
summer nights it is desirable to supply
cooler outside air. In this mode the hot air in
the dwelling is replaced by cooler outside air
as far as possible.
The bypass valve opens and closes
automatically when a number of conditions
are satised (refer to the table below for
bypass conditions).
The operation of the bypass valve can be
adjusted in step number 5, step number 6
and step number 7 in the settings menu (see
pages 39-41).
To prevent freezing of the heat exchanger
at extremely low outdoor temperatures,
the Slimline 150 features an intelligent frost
control. Temperature sensors measure the
temperatures across the heat exchanger
and, if necessary, the preheater is switched
on. This guarantees a proper ventilation
balance, even at very low outdoor
temperatures.
If, with switched on standard preheater(s),
the exchanger temperature still starts to drop
below zero, stepless unbalance is created in
the appliance.
The user information menu shows when the
Slimline 150 frost control system is activated
(see page 19).
Bypass valve open
-The outdoor temperature is higher than 10°C and
-The outdoor temperature is lower than the indoor temperature in the
dwelling and
-The temperature in the dwelling is higher than the temperature set at step
no.5 in the settings menu
(set a standard at 22°C).
Bypass valve closed
-The outdoor temperature is lower than 10°C or
-The outdoor temperature is higher than the indoor temperature in the
dwelling or
-The temperature from the dwelling is lower than the temperature set at
step no. 5 in the settings menu minus the set temperature by the hysteresis
(tolerance) (step no. 6), this temperature is factory set at 20°C (22.0°C
minus 2.0°C).

The Slimline 150 is also available as a Plus
version. This version is equipped with a
dierent control board with 2 additional
connectors (X14 & X15) with more
connection options for various applications.
Only the Plus is equipped with a 9-pole
connector (connected to X15 on control
board) that is accessible from the outside of
the appliance.
If a postheater or extra preheater is
connected to connector X14 (accessible
after opening the front panel ) the installer
must feed the connected 230 Volt cable
to outside the appliance through a strain
reliever. For this strain reliever (not supplied
with the appliance) a plug must be removed
from the position where this strain relief
must be placed.
See page 32 for more information on the
connection possibilities of connectors X14
and X15.

The Slimline 150 can be mounted directly
to the wall or ceiling using the mounting
brackets supplied for that purpose.
Because of the appliance’s weight,
mounting the appliance must
always be done by two people.
For a vibration-free result the appliance must
be mounted to a solid wall with a minimum
mass of 200 kg/m
2
. A gypsum block or
metal stud wall will not suce. Additional
measures such as double panelling or extra
studs are required in that case. In addition,
the following aspects must be taken into
account.
• The appliance must be placed level; both
lengthwise and laterally.
• The installation room must be such that a
good condensate discharge with air trap
and pitch for condensate can be made.
Make sure that under no condition
the condensate discharge is
installed at a pitch towards the
appliance.
The appliance is only suitable for
ceiling or wall mounting! Never
mount the appliance at on the
oor because of the position of the
condensate discharge bin.
• The installation room must be frost-free.
• When mounting exible ducts, bear in
mind that it must be possible to replace
them in due course.
• Make sure there is sucient free space
at the appliance to allow cleaning of the
lters and maintaining the appliance. It
must be possible to swing the door open.
Ceiling mounting:
At least 70 cm at the underside of the
appliance and a free headroom of 1.8 m; if 70
cm free space is not available, for instance
when mounting on top of a suspended
ceiling, there must be sucient room to
partly open and remove the front panel.
The front panel can be detached after
removing a lock screw at the hinge.
Make sure the lters can always be freely
removed, so there is no frame or other
obstacle at the level of the lters!
Wall mounting:
Make sure there is a free space of at least 70
cm at the front of the appliance and a free
headroom of 1.8 m.
Make sure there is at least 20 cm free space
at the appliance side where the electric
connections are located, so connectors and
sleeves remain accessible.
