1. . Introduction
1.1 About this manual
1.1.1 General
This manual describes the installation, operation and
maintenance of the comfort air curtain model CA2with
CHIPS control. The manual also provides instructions and
information on service operations.
1.2 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 How to use this manual
If you are unfamiliar with the comfort air curtain, read this
manual section by section.
If you are familiar with the device, you may use this manual as
a reference. Refer to the table of contents for looking up
information.
For CA2V and CA2Q only:
This manual makes cross-reference to the manuals of the
Daikin components (outdoor unit, indoor unit, control panel,
etc.).

supplied with the unit:
• Wiring diagram for installation and service
1.4 About the unit
1.4.1 Applications
The comfort air curtain is intended for the separation of
climates between two rooms, and for the heating and filtering
(filter class EN779-G2) of air. The unit is installed above the
doorway, across its full width.
The free-hanging model is designed for free, visible installation
above the door.
The recessed model is designed for integration into a false
ceiling or into a cove, with the inlet opening possibly at some
distance from the unit.
The cassette model is designed for installation above a false
ceiling, with the inlet opening close to the unit and with easy
access to the unit.
CA2V and CA2Q
The CA2V/CA2Q air curtain 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.

MANUAL INTRODUCTION
Version: 6.1 (05-12-2011) 7
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 temperature control is less accurate than with water
or electric heating.
• The Daikin system has to be active at all times.
Other versions and intended use.
On request, versions can be supplied for other applications.
Warning:
wApplications 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.
1.4.2 Function
The air curtain blows out a stream of heated air 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 curtains setting, the unit can also blow
unheated air.
1.4.3 Models and type designations
Ta b l e 1-2 provides an overview of available models of the
comfort air curtain and the corresponding type designations.
Combined, the type designations constitute the type code, for
instance: CA2 S-100-W-F. Not every combination is available.
If some part of the manual applies to certain models only,
these will be indicated using the corresponding type
designation, for example:
-CA

12.5.1 Particulars
Caution:
cThe supply and return pipes of the central heating system
must be connected to the correct corresponding
connections 1. The directions are indicated on the unit
using arrows.
• The maximum permissible operating pressure of the hot
water circuit is specified on the type plate (see
section 1.4.4). It is based on a water temperature of
110 ºC.
Caution:
cThe unit has an integrated water control. The central
heating connection must not be fitted with a control valve.
• The water-side control valve is automatically closed as
standard if the air curtain and/or the heating is switched
off. This can be altered at the control panel via
Menu>configuration>77. Valve open.
Caution:
cBiddle recommends the inclusion of a valve in each pipe.
• The bleed valve 2of the heat exchanger is located at the
left in the top of the unit.

Units with side connection
On request, units with electrical 12 and water-side 3
connections on the side can be supplied. The water-side
control is then not built-in, but has to be connected outside
the unit during installation.
1. Connect the valve to the connections 3as shown in the
diagram opposite.
2. Connect the valve drive to terminal 2.
2.5.2 Frost protection
The electronic control features integrated frost protection. It
works in two stages:
1. If the discharge air temperature falls to below 5 ºC:
- the control panel will temporarily display fault message
E6 (see section 5.3);
- the valve of the integral water control will open fully;
- the output on the unit gives a signal for the central
heating installation (if function 61a/b. Function of output
1/2 on the operating panel is set to Frost protection).
2. If the discharge air temperature falls to below 2 ºC:
- fault message E6 will become final;
- the fans will be switched off, but the valve of the water
control will stay open.
The frost protection is automatically lifted when the incoming
or outgoing air temperature rises to above 8 ºC.
Caution:
cThe frost protection reduces the risk of freezing but does
not warrant 100% protection.
Take the following precautions if you install the unit in a
room where frost may occur:
- Provide for constant circulation of the water at the
right temperature;
- Add up to 20% glycol to the water when the unit is not
in operation during the wintertime;
- Or drain the system and the unit (see section 6.8).
2.5.3 Connect the unit
1. Connect the unit to the central heating system.

2. Vent the heat exchanger.
3. Check the connections for leaks.
2.6 Connect the unit to a Daikin system (CA2V and CA2Q)
2.6.1 Preconditions for connection to a Daikin system
• The Daikin system must always be active when the Biddle
air curtain is active.
• A control system must be connected to the Daikin system.
This can also be a Daikin control panel that is connected
to the Biddle air curtain.
Warning:
wUnits of type CA2V may only be connected to a
Daikin VRV system.Units of type CA2Q may only
be connected to a Daikin ERQ system.These units
are not interchangeable.
2.6.2 Connection of the control system
