Other versions and intended use

Upon request, we can supply versions for non-standard applications.

w Applications 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.

1.3.2 Operation

General

An air curtain above the door opening counteracts losses of energy and comfort. Located at the opening, it blows out a stream of air and thereby brings about the following:

en-6

• The exchange of air between two rooms due to a temperature difference (convection) is counteracted.

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

Page 7

INDAC2 MANUAL INTRODUCTION

The automatic CHIPS control

Depending on the implementation, the unit may be equipped with an automatic CHIPS control.

The CHIPS control automatically adjusts the strength and heat of the unit to changing weather conditions. Thus, in all situations the energy loss is minimal and the comfort maximal.

CHIPS stands for “Corrective Heat and Impulse Prediction System”.

Control when unit ‘on’

The unit andthe automatic controlwere 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 outlet 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 as climate separation.

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.

Manual version 7.0 - North America (21-03-2017) en-7

Page 8

Note:

INTRODUCTION INDUSTRIAL AIR CURTAIN

Door response

The unit and the automatic 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 discharging air.

• Direct door response: the unit responds directly to the opening and closing of the door.

• 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.

n If the door is closed, the unit works as a room

temperature controller.

n In some situations the unit does not discharge any

air, even though it is on.

1.3.3 Type designation

The table below provides an overview of the available models of the industrialair curtain and the corresponding type designations. In combination, the type designations constitute the type code, for instance: IndAC

If some part of the manual applies to certain models only, these will be indicated with the corresponding type designation, for example:

• 150: models with discharge width 150

• H: water-heated models

• 0: horizontal models

• Auto: models with automatic control

MX-150-H2-0-Auto-480/52.

n In the illustrations in this manual, one type of unit is

used as a general example. The outer appearance of your unit may be different but its function is the same, unless stated otherwise.

25. Auto: Door response Door response

The unit can respond in various ways to the opening and closing of the door. Configure whether the response should be immediate or gradual.

Immediate change: The unit responds immediately to the

opening and closing of the door by quickly switching between the fan speeds for the door open situation and the door closed situation. Use this setting if the door is not often opened repeatedly in quick succession.

Gradual change: The speed at which the unit responds to the

opening and closing of the door is based on the open/closed ratio. If the door opens repeatedly in quick succession, the unit adjusts gradually, so that it does not need to start up completely over and over again and high fan strengths (with attendant noise) are not so necessary. Use this setting if the door is regularly opens repeatedly in quick succession and the changes between low and high fan strengths are undesired.

Fan speed

Set what the fan speed must be if door is closed. This is also the minimum setting with door open.

If this function is set to 0 (fans off) or 5, then, because of the room temperature control, the fans can nevertheless start working while the doors are closed.

Room temperature control

If the door is closed, the unit helps to keep the room at the correct temperature controller. If the set fan setting for closed door has been set to 0 or 5, this function does not work.

If room temperature control is indeed desired, the function can still be activated here.

Fan speed for room temperature control

Set the percentage of the fan speed that must be used for room temperature control if this has been set via menu 25.

Auto: Door response.

en-66

As soon as the room temperature has been reached, the fans switch off.

Page 67

INDAC2 MANUAL OPERATION WITH B-TOUCH

Note:

Stand-by heating

The control can be set in such a way that heat is immediately available when the door is opened. This is a percentage of the maximum heat available for this function. The maximum heat depends on the outdoor temperature, among other things.

Set the amount of heating that must be available when the door is opened:

• If immediate heat is important, set a high percentage.

• If saving energy is important, set a low percentage.

n The room temperature control can affect this

amount of available heat.

26. Manual: Door response Set the way in which the unit in manual mode should respond

to the opening and closing of the door:

•Direct response.

• No response. (The unit always works on the set fan setting)

31. Maximum strength In order to restrict the sound level, the maximum fan speed

can be limited. This function only has effect on the automatic mode.

Use of this function can reduce comfort.

32. Deceleration time You can set a post-rotation time for the fan. Here, set the

period of time it should take for the fan to decelerate from maximum speed to standstill.

33. Boost function If there is a great difference between the desired room tem-

perature and the actual room temperature, the fan speed can be increased in order to reach the desired temperature more quickly.

Set the temperature difference at which the boost function should be activated and what the fan’s increase in speed should be.

Use this function if the unit is also used for heating the room.

If 61. Function of outputs is set to value Risk of freezing, a contact on that output is also made when the actual temperature is higher than this setting.

41/42/43 Operation at higher outdoor temperatures

As the outdoor temperature rises, the need for climate separation and heating changes. In functions 41, 42 and 43 you specify at what outdoor temperatures the heating and the fans must react to this.

SITUATION NEED FUNCTION OPERATION

It is colder outdoors than indoors.

It is approximately as warm outdoors as indoors.

Heated climate separation Normal operation Heating: on

Fans: on

Ambient climate separation 41. Heating OFF temperature Heating: off

Fans: on

No climate separation 42. Fan OFF temperature Heating: off

Fans: off

It has become much warmer outdoors than indoors.

Ambient climate separation 43. Temperature unheated usage Heating: off

Fans: on

41. Heating OFF temperature

If the outdoor temperature rises above this point, the unit’s heating is switched off.

A higher value gives more comfort, a lower value saves energy.

42. Fan OFF temperature

When the outdoor temperature rises, there is less need for climate separation. In order to save energy, the fans can be switched off at a pre-set outdoor temperature.

Set this value at 50°C in order to leave the fans on all the time.

43. Temperature unheated usage

When the outdoor temperature becomes higher than the desired room temperature, there is a need for climate separation without heating. Set the outdoor temperature at which the unit should function in an unheated mode in order to keep the heat out.

Set this value at 50°C in order to leave the temperature control on all the time.

en-68

Page 69

INDAC2 MANUAL OPERATION WITH B-TOUCH

Note:

44. Outdoor temperature The automatic CHIPS control needs an outdoor temperature

in order to calculate the optimal setting. Without temperature data from a sensor, the outdoor temperature is estimated on the basis of the month of the year and your country. Climate data are used for this.

You can only use the function if the date and time have been correctly set. After selecting your country, you can modify the monthly temperatures in accordance with your wishes. Since this is only an estimation, it may be that your unit does not function optimally.

n The automatic control works less efficiently without

an outdoor temperature sensor.

45. Extra frost protection For water-heated models only

When the unit is switched off, the water valve closes by default.

By default, the unit is equipped with frost protection. You can additionally protect the unit against frost damage by leaving the water valve partially open at certain temperatures.

Select Valve position and set the opening percentage of the valve so as to always keep a flow running over the heat exchanger in the unit.

Set the maximum outdoor temperature at which the additional frost protection must be activated. When the temperature exceeds this value, the additional frost protection switches off again.

46. Maximum discharge temperature The controller limits the discharge temperature to a maxi-

mum of 50°C. Possibly set a lower value in order to save energy.

47. Overheat protection If the actual room temperature becomes higher than the pre-

set room temperature, the heating can be switched off in order to prevent the room from becoming too warm.

Set the temperature above which the heating must be disabled.

n This function can only be used if the unit is set to

automatic.

n If this function is activated, then function 6. Minimum

air temperature is ignored.
