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 tempera-
ture 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 sup-
port 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: SFiSP-100-W-F.

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 multi-
ple 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 work-
ing 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 regu-
lated 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:
wNEVER change the settings of the other DIP
switches.
4. Close the unit.
With the other units, leave this setting unchanged.

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 oper-
ated 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:
nDo 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
off the heating, or no power is supplied to the unit.

2.9 Installing the controller
2.9.1 Mounting and connecting the touchpad
controller (SFi)
Note:
nTake the following into account, otherwise faults may
occur:
- Keep control cables away from electromagnetic fields
and interference sources such as high-voltage cables
and fluorescent-light starters.
- Stretch control cables out or wind them bifilarly.
1. Drive two screws into the wall at a centre distance of 80
mm Keep a clearance of approx. 2 mm between screw
head and wall.
2. Hook the control panel on the screws using the key holes.
3. Connect the controller cable to socket 1in the top of the
unit.
Multiple units operated from one control panel
•OnlySFi-type units can be simultaneously operated using
one single control panel.
• Up to 100 units can be connected to one single control
panel. The units must be interlinked using special control
cable from Biddle.
• The total length of the control cables is not to exceed
100m.
•If a unit has been set as master: the control panel may be
connected to any unit.
Note:
nUse only control cables from Biddle. Standard modular
telephone cable is not suitable.
1. Interlink the units: Connect the control cable of the unit to
which the controller is linked to socket 2, and that of the
next unit to socket 1.
