1.3 About the unit

1.3.1 SensAir

The unit

Among other things, the unit contains:

• heating element 1(depending on the type of unit)

The heating capacity is controlled by the unit. For this pur-

pose, water-heated models have an integrated control

valve.

•fans2

The speed (strength) is controlled by the unit.

• air inlet sensor 3

•dischargesensor4

•For models with water heating or connected to a

Daikin system:

heating medium sensor 5

• IR sensor 6

• connection for

the b-touchcontrol panel 7

• connection for Modbus 8

The b-touch control panel

In addition to menus for the settings, the b-touch control panel

contains, among other things:

• temperature sensor 9

• connection for extra temperature sensor 0. With this, the

temperature at a different place in the room can possibly

be measured: for example, at a place where draughts

quickly occur.

1.3.2 Applications

General

The purpose of the Comfort air curtain is to separate cli-

mates between two rooms and to heat and filter air (filter

class EN779-G2). The unit is installed horizontally above the

doorway, across its full width.

Mounting types

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 an alcove, 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; the unit must

be easily accessible.

INTRODUCTION COMFORT AIR CURTAIN

Comfort air curtain for Daikin system

With models SRV and SRQ:

The air curtain is connected to a direct expansion system

from Daikin. The air discharged by 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.

This 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 use

Upon request, we can supply versions for non-standard appli-

cations.

Warning:

wApplications other than those described

above are deemed to be usage other than for

the intended purpose. Biddle is not liable for

damage or loss resulting from usage other

than for the intended purpose. Usage for the

intended purpose also entails observance of

the instructions in this manual.

1.3.3 Operation

General

In an opening between two rooms, air is exchanged through

pressure and temperature differences (convection). This leads

to energy losses and detracts from the comfort in the room.

For reasons such as accessibility, it may nevertheless be desira-

ble to leave the door standing open. An air curtain above the

door opening counteracts losses of energy and comfort. At

the location of the opening, it blows out a stream of air and

thereby brings about the following:

• The exchange of air between two rooms due to a temper-

ature difference (convection) is counteracted.

• The air that enters at floor level due to draught is possibly

heated.

SENSAIR MANUAL INTRODUCTION

Manual version 1.0- North America (13-09-2016) en-9

The automatic CHIPS control

The CHIPS control automatically adjusts the strength and heat

of the unit to changing weather conditions. Thus, in all situa-

tions the energy loss is minimal and the comfort maximal.

CHIPS stands for ‘Corrective Heat and Impulse Prediction System’.

Control when unit ‘on’

The unit and the auto-active control have been developed for

situations in which the door stands open.

For the most efficient climate separation and preservation of

comfort it is important that the airflow just touches the floor

and is heated sufficiently. The unit continuously measures the

values that are needed in order to achieve this:

1. The installation height (entered in the control panel)

2. The temperature difference between the two rooms:

- outdoor temperature

- room temperature

3. The temperature of the discharged air

As soon as the situation changes, the control adjusts the out-

let flow rate and the temperature of the airflow to that.

Control with unit ‘off’

If the unit is off – at night, for example – it is not active.

If it is off, the unit can indeed still perform other functions:

• The unit can be set to keep the room at a minimal ‘night’

temperature.

• Water-heated models are equipped with integrated frost

protection.

Door response

The unit and the auto-active control have been developed for

situations in which the door stands open.

If the door is not continuously open, the operation can be

adjusted to this:

• Normal operation: the unit is always active.

• Direct door response: the unit responds directly to the

opening and closing of the door.

INTRODUCTION COMFORT AIR CURTAIN

en-10

• Gradual door response: the unit responds to the opening

and closing of the door. The speed of response is based on

the open/closed ratio.

Note:

nWith the door closed, the unit can be set to keep

the room at a minimal room temperature.

Note:

nIn some situations the unit is not active, even though

it is on.

1.3.4 i-sense infra red technology

The i-sense infra red technology makes it possible to use the

automatic CHIPS control without adding external controls

such as an outdoor temperature sensor and a door contact

switch.

Next to the discharge grille is an IR sensor which measures

the temperature in a strip of 8 planes perpendicular to the

door opening. As a result, the sensor provides the controller

with diverse information:

Note:

nThe temperature of a floor surface changes gradually.

• indoor temperature (T8)

• outdoor temperature (lowest measured value of T1, T2

and T3)

Note:

nAn outdoor temperature is only measured if the IR

sensor recognises the door as being open.

• door position

If the difference between T5 and T1, T2 or T3 is at least

3°C is, it is assumed that the door is open.

Note:

nAn outdoor temperature can only be recognised if

the unit is on and climate separation is active.

• signal for quick start or 30 minutes on (T7 and T8)

If the measured value briefly changes, it is assumed that

someone is walking below the sensor.
