1.1 Warnings
All installations must be in accordance
with the regulations. These instructions
must be handed to the user on comple-
tion of the installation. Installers and ser-
vice engineers must be able to demon-
strate competence and be suitably
qualified in accordance with the regula-
tions. To ensure continued and safe op-
eration it is recommended that the ap-
pliance is serviced annually. The air cur-
tain outlet/inlet grille must not be ob-
structed during use. Any modifications
made to the unit not approved by Con-
sort will void manufacturer’s warranty
and potentially create a hazard. The ap-
pliance is NOT intended for use by per-
sons (including children) with reduced
physical, sensory or mental capabilities
or lack of experience or knowledge un-
less they have been given instruction
concerning use of the appliance by a
person responsible for their safety. Chil-
dren should be supervised to ensure that
they do not play with the appliance.
Parts of the heater can become very hot
when in operation and cause burns. The
heater is not equipped with a room ther-
mostat and should not be used in small
rooms as it will overheat.
1.2 Health and Safety
Please read these instructions thoroughly be-
fore installing the appliance. Sole liability
rests with the installer to ensure that all site
safety procedures are adhered to during in-
stallation. Sole liability rests with the installer
to ensure that protective safety wear such
as hand, eye, ear and head protection is
used during installation of the product. En-
sure that all anchoring points are suitable for
the weight of the appliance.
1.3 Electrical Supply
This heater must be permanently connected
to the electricity supply via an all pole switch
having 3mm gap on each pole. There are
no exceptions.
All units must be wired in accordance with
I.E.E. regulations for the Electrical Equip-
ment of Buildings.
BMS control, time switches and door inter-
locks can be installed at the discretion and
responsibility of the installer
1.4 Location
All units should be installed directly over
the door opening. It is recommended that
the air curtain is installed on the inside of
the building.
Care must be taken to allow complete
free air movement into the inlet grilles of
the unit to ensure correct working opera-
tion of the air curtain. The discharge open-
ing should be as close to the top of the
door as possible and cover the entire door
width.
Units can be mounted adjacent to each
other to cover the full door opening across
wider entrances.
1.5 Clearance Distance
It is recommended that a minimum clear-
ance of 50mm is allowed above the heat-
er. The clearance allows for cable entry
and additional air inlet. It also prevents sur-
faces overheating.

2.1 Introduction
This instruction manual describes the
ScreenZone Recessed range of air curtains.
They are designed for discreet positioning
above the doorways of retail or commer-
cial premises up to 3.4m ceiling height.
Models come in a range of wattages from
6-16kW total power.
Models are available in 1.3m and 1.5m
lengths, made up of 2 blower units. For
wider doorways, up to 7 air curtains can
be easily interconnected using CAT5/CAT6
RJ45 networking cable when using the
ACMC.
It is recommended that this control cable
is run separately within its own trunking to
avoid external interference.
The air curtain can be controlled by op-
tional Touchscreen controller (not supplied
with the heater) , mechanical switches or
BMS.
2.2 Mechanical switch Controller
Each air curtain is supplied with a HE8408
mechanical switch. More details can be
found in the Installer wiring section. This con-
troller will provide 2 fan speed and 3 heat
setting options.
2.3 Colour Touchscreen Controller
Optional Colour Touchscreen controller (not sup-
plied with the heater) giving options for 8 fan and
8 heat settings can be mounted up to 50m from
the air curtain. Optional BMS control, remote
thermostats and door interlocks can be installed.
The electronic touch screen controller shown on
the picture below allows the user to control either
a single air curtain, or a network of up to 7 air cur-

tains with the same settings.
The controller is designed to be mounted on
a surface double gang back box, and is
powered by an RJ45 connection. The con-
troller will not fit metal or dry lining back box-
es.
The cable length between the base unit and
the controller can be up to 50 metres.

4.1 Mounting
All units should be installed horizontally directly
over the door opening. Before fitting or wiring
the air curtain, ensure the outlet is facing the
doorway.
Care must be taken to allow complete free
air movement into the inlet grilles of the unit to
ensure correct working operation of the air
curtain. The discharge opening should be as
close to the top of the door as possible and
must cover the entire door width.
Units can be mounted adjacent to each oth-
er to cover the full door opening across wider
entrances.
4.2 Electrical Supply Entry.
The cable entry is located in the middle of the
heater. The top of the heater has 2 x 20mm
holes and the side of the heater has 2 x 20mm
holes. This should suit most installations.
4.3 Installation
It is the sole responsibility of the installer to en-
sure that the points of attachment to the
building are sound. Consultation with the con-
sultant/architect or owner of the building is
recommended to ensure that a sound, me-
chanically stable installation is achieved.
All attachments must be capable of support-
ing the weight of the product .
Each unit has 2 fixing brackets from which it is
suspended. The brackets may be removed to
assist in passing the air curtain through the
recess then reattached when in-situ.
Either drop rods or catenary wire can be used
to fasten the air curtain to the ceiling support
structure.
The height between the ceiling face and the
top of the air curtain case needs to be adjust-
ed to circa 140mm to enable the grille assem-
bly to fit flush with the ceiling. Adjust accord-
ingly.
After fitting the product in the ceiling recess
and adjusting the height to ensure that the
grille sits flush to the ceiling (when re-fitted)
take the grille assembly and refit using the
screws removed.

The air curtain monitors the fan speed,
power output and heatsink temperature. In
the event of a fault the red LED on the sec-
ondary PCB flashes:
The red LED flashes a number of times and
then pauses. The number of flashes de-
notes the fault.
The heater is equipped with electronic over
heat protection and also over temperature
cut-outs. There are four cut-outs on each
air curtain. They are located just In front of
the element. In the unlikely event of elec-
tronic failure, the mechanical cut-outs will
switch off power to the heating element. In
order to reset cut-outs, isolate the heater
from power, allow the heater to cool and
remove the cover and carry out inspection.
The cut-outs will reset automatically when
unit is isolated and cooled down.
The cause of cut-outs operating should be
investigated before resetting.
When the air curtains are powered up in
standby mode, a green LED on the main
board shows that the 12V power supply is
working correctly:
When heat or cold blow is demanded the
secondary PCBs are powered. A second
LED on the main PCB shows that the second
12V power supply is working correctly:
A fault with the auxiliary power is indicated
by a flashing orange LED on the main PCB:
A green LED on the secondary PCBs shows
that they are receiving 12V power:

9.1 BMS Connection
The heater is compatible with BMS systems using
MODBUS protocol.
The connection to BMS system can be made using
one of the RJ45 connectors.
Only one means of control can be used at the
same time. If BMS is used to control the heater, the
colour screen controller must not be used.
The BMS can control fan speed and heat output
and also read and report the heater status.
Speed can be set in the range of 600 - 1700RPM in
1RPM steps. If the speed is set below 600RMP, the
heating element is automatically disabled. Care
has to be taken when selecting speed. The fan
speed should be always correct for the selected
heat output. If the speed is too low, the heater can
overheat.
Heat output can be set in the range of 0 - 100% in
1% steps.
9.2 MODBUS Protocol
The DIP switches 1, 2 and 3 are used to
configure each air curtain with a unique
address.
RJ45 cable can be used to network up
to 7 air curtains in a daisy-chain configuration.

10.6 Timer - time schedule
There are 2 timer periods for each day available.
Tapping the slider in the top right corner will
change between 1 or 2 time periods.
The times for the first time periods are on the top of
the screen, the times for the second timer period
are on the bottom of the screen. Times can be ad-
justed in 15 minute intervals using the buttons.
When the timer is active, an icon will appear on
the home screen giving information about the next
switch time.
10.7 External switches
There is a provision for 2 remote switches than can
be wired into the air curtain with. The switches must
be voltage free type, NO or NC configuration.
SW1 can be connected to a door switch or occu-
pancy sensor installed in the door area. When the
function is activated, the door switch will enable
the air curtain when the door is open and disable it
when the door is closed. The second slider is used
to configure the system for the correct switch type.
When the air curtain is disabled by the door switch,
the heater will operate at a low fan speed. This will
allow for a fast start-up when the door is opened.
When SW1 is active, the home screen will show the
status of the door switch.
SW2 is intended for a remote switch that can be
used to disable the air curtain from a remote loca-
tion. Usually this would be a simple BMS or external
timer connection. Once disabled using remote
switch the air curtain can’t be controller by the
touchscreen controller and will remain disabled
until enabled remotely.
10.8 Operating Mode selection
One of four operating modes can be selected.
Each mode uses a different method of select-
ing heat and fan settings when the air curtain is
not in stand-by mode. Use the settings button
to configure each mode.
10.9 Manual Mode
In manual mode user can select required fan
and heat output by tapping + or - symbols on
the home screen next to the fan and heat bars.
There are 8 fan speeds and 8 heat settings
available. It is possible set maximum and mini-
mum limits for fan speed and heat output.
Once limits are set and functions activated,
only limited fan speed and heat output will be
available on home screen when in manual
mode.
