About the unit
1.3.1 Applications
General
The purpose of the Comfort air curtain is to separate climates between two rooms and to heat and filter (filter class
EN779-G2) air. The unit is installed above the doorway, across
its full width.
Manual version 7.0 (15-05-2013)

INTRODUCTION
COMFORT AIR CURTAIN
Mounting methods
The free-hanging model is designed for free, visible installation
above the door.
The recessed model is designed for installation into a false
ceiling or into an alcove where the air inlet may be at some
distance from the unit itself.
The cassette model is designed for installation above a false
ceiling where the air inlet is close to the unit and the unit is
easily accessible.
Comfort air curtain for Daikin system
On models CA2V and CA2Q:
The air connection is connected to a Daikin direct expansion
system. The air blown through the unit is heated by the cooling medium. The air curtain is controlled and operated partly
by the Daikin system and partly by the Biddle system.
The system has a number of limitations:
•
The unit is only suitable for use in Daikin direct expansion
systems.
•
The unit is not suitable for cooling.
•
The Daikin system has to be active at all times.
Other versions and intended usage.
On request, versions can be supplied for other applications.

Warning:
Applications other than those described
above are not considered to be an intended
use. Biddle assumes no responsibility for
damage or injury resulting from applications
other than the intended use. The intended
use also implies observance of and
compliance with the instructions in this
manual.
1.3.2 Mode of operation
The air curtain blows out a warm air stream straight down,
thus achieving the following:
•
The exchange of air between two rooms due to temperature differences (convection) is stopped.
•
The cold air entering across the floor due to draught is
heated.
Depending on the air curtain's setting, the unit can also blow
unheated air.
1.3.3 About the automatic CHIPS control
The CHIPS control matches the strength and heat of the air
curtain to changing weather conditions. This reduces energy
consumption and improves comfort through selection of the
optimum setting under all circumstances. CHIPS stands for
“Corrective Heat and Impulse Prediction System”.
The operation of the air curtain is based on the outside temperature and the room temperature near the air curtain.
1.3.4 Type designation
The table below provides an overview of available models of
the Comfort Air Curtain and the corresponding type designations. In combination, the type designations constitute the
type code, for instance: CA S-100-W-F.
If some part of the manual applies to certain models only,
these will be indicated using the corresponding type designation, for example:

Dirty filters reduce the effectiveness of the air curtain. It is
therefore necessary to clean or replace the filters at regular
intervals. The filter contamination is either measured with the
optional filter sensor or calculated.
With the optional filter sensor, the unit measures the filter
contamination every 24 hours by running at the highest fan
speed for 40 seconds. You can set the check time for this in
the menu.

mode.
Use of this function can reduce the comfort.
59. Sensor X82
The sensor connected to terminal X82 on the unit can act as
either an outdoor sensor or as a pipe sensor on the supply
pipe of the central heating system. This sensor is used in the
automatic control of the air curtain.
6XSSO\WHPSHUDWXUH
ZDWHU>ƒ&@
Pipe sensor
The outdoor temperature is derived from the water temperature. For this you need a pipe sensor on the supply pipe of the
central heating system and a weather depended control of the
central heating system.
7HPSHUDWXUH
The outdoor temperature is based on the heating curve of the
supplied water. This curve is defined by three points of outdoor temperature and water temperature.
7HPSHUDWXUH
7HPSHUDWXUH
2XWGRRUWHPSHUDWXUH>ƒ&@
The first point is for the high outdoor temperature, the last
point for the low outdoor temperature. Make sure that the
limits of all temperatures correspond to the temperatures that
can occur.
As this is only an estimation, the working of the air curtain
might be less optimal.

CA2 MANUAL
60. Function of input
OPERATION
The unit has one input which can be used to have a function
controlled by an external accessory such as a door switch,
thermostat or a signal from a building management system
(BMS).
If several units are connected to one control panel, only one
input can be used. The effect of this input is then the same for
all the units.
The function Unit off locally has an effect only on the units
whose inputs are in use.
When the timer is in use, the function Switch all units on/off
of the input on the unit is deactivated, irrespective of this setting.
With the setting Switch all units off a jumper must be laid to
the input for all the other connected units.
61a/b. Function of output 1/2
The unit has an interface for two output signals: These can be
used, for example, for controlling the central heating or cooling system, or for transmitting status reports to a BMS.
The outputs function independently of one another.
69. Temperature display
The room temperature is displayed as default. With this function you can select another temperature to display or switch
off the temperature display.
72. Error display
Some fault messages may be caused by external factors such as
the central heating system and do not necessarily have an
influence on the function of the air curtain.
Use this function to suppress these messages. Messages concerning safety are always displayed.
76. Release delay input
When you are using an input, you can allow the effect of an
incoming signal to continue for some time after the signal has
passed (‘release delay').'This setting can be used, for example,
in combination with a door switch to allow the unit to continue to run for a short time after the door has been closed.
77. Valve position unit off
When the unit is switched off, the valve in the unit is closed by
default.
Select Valve open and set the opening percentage of the valve
to always keep a flow over the heat exchanger into the unit.

OPERATION
78. Valve position fans off
COMFORT AIR CURTAIN
When the fans are switched off, the position of the water
valve depends on the temperature control.
Set the opening percentage of the valve to always keep a flow
over the heat exchanger in the unit when the fans are off. This
is relative to the position the valve has when the fans are running.
This way heat is always directly available
80. Fan off temperature
When there is only a small difference in temperature between
outdoors and indoors, there is less need for a climate separation. In order to save energy, the fans can be switched off
when there is only a small difference in temperature.
Set this value to zero to allow the fans to run at all times.
82. Installation height
In order to use the automatic control as efficiently as possible
and with minimum energy consumption it is necessary to set
the installation height of the air curtain correctly.
If there is a continuously large draught through the door, this
value can be increased in order to adapt the strength of the air
curtain.
The installation height is the distance h between the floor and
the underside of the discharge grille.
84. Heating off temperature
If the outdoor temperature rises above this setting, the heating of the air curtain is switched off.
A higher value offers greater comfort, a lower value saves
energy.
86. IR sensor
The unit can be optionally equipped with an IR sensor in the
discharge grille.
This sensor is used to give an indication of the number of people passing underneath the air curtain. This indication can be
read out in the status screen and in the log-files.
The IR sensor can also be used to switch on the unit for 30
minutes every time it detects motion, and it can be used
instead of a door switch. Choosing this last function disables
the input on the unit for this function.

OPERATION
Two wireless sensors can be connected to the system. The
wireless outdoor sensor replaces the wired outdoor sensor.
The function of the wireless indoor sensor depends on the
sensor chosen in function 51. Indoor sensor:
88. Outdoor temperature
•
When the air curtain sensor is selected as indoor sensor
for the control, both the wireless sensor and the air curtain sensor are used for calculating the air curtain strength
and the air temperature.
•
In case the control panel is selected for the control, the
temperature of the wireless indoor sensor is used.
The CHIPS automatic control needs an outdoor temperature
to calculate the optimal setting. When no outdoor sensor is
connected, the outdoor temperature is estimated on the
month of the year and your country. Climate data is used for
this.
To use this function the date and time need to be correctly
set. After selecting your country you can modify the month
temperatures to your wishes. As this is only an estimation, the
working of the air curtain might be less optimal.

Replacing or cleaning the filter
The filter must be cleaned regularly. A dirty filter may cause
inadequate heating as well as a high noise level. The interval at
which the filter is to be cleaned depends on the local conditions.
By default, filter contamination is monitored on the basis of
the amount of time that the unit is in operation. As an option,
the unit can be fitted with a sensor to measure filter contamination. You can change the time between filter cleaning sessions by adjusting the maximum life of the filter or the cleaning
interval.
You can clean the filter with, for instance, a vacuum cleaner.
After some cleanings, however, the filter must be replaced.
New filters are available from Biddle.
4.1.1 Procedure when replacing the filter
1. Select menu > Filter > Clean filter on the control panel.
2. Wait until the fans have stopped and the heat exchanger
has cooled down.
