1.2.3 Related documentation
Besides this manual, the following document comes with the
unit:
• wiring diagram for installation and service purposes.
1.3.1 Applications
The comfort air curtain is designed to separate the climates
between two rooms. The unit is installed above the doorway,
across its full width.
By installing multiple units side by side, openings of unlimited
width can be screened off in steps of 50 cm.
The model is designed for free, visible installation above doors
as well as for integration into coves or suspended ceilings.

MANUAL INTRODUCTION
1.3.2 Working
The air curtain blows a stream of either heated or unheated
air straight down, achieving the following:
• The exchange of air between two rooms due to temperature differences (convection) is stopped.
• For heated air: the air entering across the floor due to
draught is heated.
• For unheated air: warm outside air is kept outside to support the air-conditioning in the room.
The air curtain is designed such that there is no need for air
filters.
1.3.3 Models and type references
Table 1-2 on page 7 provides an overview of the available
models of the comfort air curtain and the corresponding type
references. Combined, the type references constitute the type
code, for instance: SFi
SP-100-W-F.
If some part of the manual applies to certain models only,
these will be indicated using the corresponding type refer
ence, for instance:

MANUAL INSTALLATION
2.7 Setting a unit as master (SFi , optional)
With multiple units operated from one control panel
only
2.7.1 Working
On delivery, each unit comes set as equal. If you apply multiple units with one control panel, the units work independently:
• If you connect an external control (see section 2.8.1), only
the unit to which it is connected to will respond to it.
• With the automatic temperature control (see section
3.2.3), the temperature is regulated independently in each
unit.
You may choose to set one unit as master. By this, the working of the units will be linked:
• If you connect an external control to the master unit, the
other units will respond to it in the same way.
• With the automatic temperature control, all units are regulated from the master unit.
2.7.2 Setting the unit
With the unit that is to be set as master:
1. Open the unit. (see section 6.2)
2. Take out the PCB if necessary (see section 6.3)
3. Set DIP switch no. 3 on the PCB into the ’ON’ position.
Warning:
w NEVER change the settings of the other DIP
switches.
4. Close the unit.
With the other units, leave this setting unchanged.

INSTALLATION COMFORT AIR CURTAIN
2.8 Connecting external controls (SFi , optional)
2.8.1 Input for external control
To the input, you may connect a door contact switch and/or a
BMS system.
The connector is located in the top of the unit. It comes with
a bridge in it on delivery. The connector is wired to the PCB
(connector INHIBIT).
The input is fit for potential-free switch contacts. It is operated as follows:
• contact closed (or with a bridge): The unit works normally.
• contact open: The unit remains switched off.
• with a resistance across the contact (3,3 kΩ): The unit works,
but the heating remains switched off (Summer setting).
Multiple units operated from one control panel
To let all connected units respond to the external control in
the same way:
1. Set one unit as master. (see section 2.7)
2. Connect the door contact switch to the master unit.
Note:
n Do NOT remove the bridges from the other units.
2.8.2 Output for fault signal indication
To the output, you may connect a BMS system.
The connector is located on the PCB (connector HEALTHY).
The output works as follows:
• 24V DC: The unit is working normally.
• no potential: Either the high-limit thermostat has switched

2.10 Integrating the unit
The SF is as standard fit for integration into coves or above
2

suspended ceilings. To that end, the discharge section pro
trudes 24mm from the bottom of the unit. If that is not
enough, the unit can be supplied with a loose telescopic dis
charge grille instead of the standard mounted discharge grille.
Optionally, an air intake grille for integration can be supplied.
2.10.1 Mounting the telescopic discharge grille
1. Make a hole in the ceiling for the discharge section (see
Ta b le
2-3 for the dimensions).
2. Using the supplied screws, fix the two angle profiles 1 to
the unit, along the edges of the discharge opening.
3. Slide the telescopic discharge grille 2 into the unit's dis-
charge opening until you reach the desired height.
4. Fix the discharge duct to the angle profiles 1 using the
supplied screws.

MANUAL OPERATION
3 . . Operation
This section describes the functions you should know for the
day-to-day use of the comfort air curtain.
3.1 Three-speed switch (SFs )
The three-speed switch of the SFs allows you to switch the air
curtain On and Off and to set the strength of the air curtain.
The three-speed switch is used for units without heating
(SFs
A) as well as for water-heated units (SFs W) either with-
out discharge temperature control or with a fixed discharge
1
temperature.
3.2 Touchpad controller (SFi )
3.1.1 Setting the air curtain strength
• Turn knob 1 to the desired mode:
0 = Off
1 = Low
2 = Medium
3 = High
Recommended air curtain strength
To achieve maximum climate separation with minimum energy
consumption, Biddle recommends to select the lowest
strength at which no draught occurs.
All functions of the SFi can be operated from the touchpad
controller. The controller allows you to:
• switch the air curtain On and Off;
• set the strength of the air curtain;
• enable and disable heating;
• regulate the desired room temperature;
• control the desired heating capacity.

• Press key 1 briefly to switch the air curtain On or Off.
Upon switching off the unit, the heat and air-flow settings are
retained. If heating is enabled, the unit will keep on running at
low speed for another minute.
3.2.2 Setting the air curtain strength
You can set the strength of the air curtain by choosing from 3
fan speeds.
• Press key 4 to increase the air curtain strength by one
step.
• Press key 3 to decrease the air curtain strength by one
step.
LEDs on the controller indicate the air curtain strength.
Recommended air curtain strength
To achieve maximum climate separation with minimum energy
consumption, Biddle recommends to select the lowest
strength at which no draught occurs.
3.2.3 Enabling or disabling heating
Depending on the type of the unit, the heating of the air curtain can be controlled automatically and manually. This only
applies for the types SFi

Automatic temperature control
In the Automatic mode, the unit reads the air inlet temperature and automatically selects the heating level required to
reach or maintain the preset air temperature level.
• Press key 2 to enable or disable automatic temperature
control.
If automatic temperature control is enabled, the LED next
to the text “AUTO” on the controller will be lit.
•Keys 5 and 6 allow you to regulate the desired room
temperature.
If the first LED is lit, heating is disabled. The next LEDs

indicate the temperature setting from 18°C to 24°C. This
temperature is read in the unit’s air intake section and may
slightly differ from the real room temperature.
Setting heating manually
In the Manual mode, you can set the heating at full or half
capacity or you can disable heating.

3.2.4 Enabling or disabling Automatic restart
When the supply power is interrupted, you can have the unit
operate in either of the following ways:
100%50%off
• Automatic restart (default setting): The control panel retains
all settings, and the unit will continue to work in the same
way when the power is restored.
• Manual restart: The unit remains off when the power is
restored.
To change this setting:
1. Switch the unit on with key 1.
2. Hold down key 2 until the LED next to “AUTO” flashes.
3. Press key 3 to toggle the setting.

4.1 Cleaning the unit
You may clean the exterior of the unit with a damp cloth and a
domestic cleaner. Do not use any solvents.
Caution:
c Make sure no water runs into the unit.
4.2 Scheduled maintenance
Biddle recommends to have the following inspection and maintenance works performed by an installer or other technical
expert each year.
• Check if the heat exchanger or the electric heating elements are clean. Settled dust may cause unpleasant smells.
• Gently remove dust with a vacuum cleaner.
Caution:
c The fins of the heat exchanger are delicate parts.
Warning:
w The fins of the heat exchanger are sharp.
• Check the operation of the fans.
