SOUND TRANSMISSION

When a unit is positioned next to a wall, low frequency sound can

generate vibrations in the wall, even if the sound level from the

unit is acceptable. Generally the unit should be positioned against

a wall to a room that is not sensitive for noise. When this is not

possible the unit should be positioned 400-500 mm from the wall.

Duct lead-through must be designed with care so that rigid con-

nections between the duct and wall do not occur. In addition, the

seal around the duct must be carefully installed to prevent the

transmission of noise to areas. For sensitive installations it may

be a good idea to connect ducts using ﬂexible connections.

If the ﬂoor structure is weak, noise can be transmitted to other

areas in the building. Use of a heavy insulating mat can prevent

that problem.

TRANSPORT

Use a fork lift truck, pallet truck or platform trolley for transport on

site. The unit can be lifted from the front or from the side.

To move size 06 through a 900 mm opening remove the door and

the center strut. See section 12.3.

NOTE! The weight of the duct system

with components must not lay weight on the unit.

4. CONNECTIONS

4.1 DUCT CONNECTIONS

Size 03, 04 (315 mm) have circular duct connections. Size 06 has

rectangular duct connections (600 x 300 mm).

4.2 POST HEATER, ELECTRICAL

The electrical post heater for size 06 is duct mounted, see sepa-

rate instruction. The rectangular connection is PG on the unit and

the accessories. If the unit is selected with ﬂange connection the

unit is delivered with an adapter for ﬂange. This can be placed on

the unit or on the accessories. If the accessories are not placed

directly at the unit more adapters are available with the code

RDTZ-25-06-1.

4.3 POST HEATER, HOT WATER

Connect the pipes for the heating coil inside the unit according to

pictures below. View from gables.

NOTE! To avoid freezing the temperatures for frost

protection must not be set too low. If the building

has to be left unheated for long periods during

winter, the water must be drained from both the

pipework and the heating coil.

WARNING! Wear protective gloves

when using a ﬁn comb.

Warning - hot water!!

FläktGroup takes no responsibility neither for

the connection of air heaters to the heating

system, nor for damage or injury caused by

incorrect planning, installation or maintenance

of this system. Pipework, valves etc. are to be

designed due to pressure drop and function, not

the dimensions of the air heater connections. The

weight of the pipe work system with components

must not lay weight on the water coil.

PREVENTING FREEZING

There is a risk of freezing in the hot water coil at low outdoor

temperatures. This can cause water damage. The risk can

appear:

1. if the temperature of the water is too high. The risk increases

in spring and autumn. Adjust the water temperature in relation

to the outdoor air temperature.

2. if the post heater is oversized. Decrease the temperature of

the water to increase the water ﬂow.

FINS

Any deformed ﬁns can be adjusted using ﬁn comb EQAZ-14.

VENTING

The air must be properly vented from the system to ensure good

function. The venting is made through the pipe system.

6.11 EXTERNAL CONTROL/EXTENDED FUNCTIONS

The unit can be controlled by an external source, e.g. push but-

tons to activate proﬁles and proﬁle bypasses. External control

inputs can also be used to vary fan speed from a remote source.

For conﬁguration see chapter 9, control functions.

If conﬁgured, External Stop is a NC circuit which lets the unit

operate according to the current proﬁle number. If the contact is

open, the unit is switched off and a message is shown on the

HMI.

External Control contacts are used as

1. NO circuits activating conﬁgured proﬁles with Ext. Control 1

being low and Ext. Control 2 high priority.

2. Push button circuits activating a proﬁle bypass for a conﬁgured

time with Ext. Control 1 being low and Ext. Control 2 high

priority.

3. External setpoints for fan control (manual/volume ﬂow/

pressure) with Ext. Control 1 being fan control 2 and Ext.

Control 2 fan control 1.

Please note that only two functions can be conﬁgured at the

same time for external controls.

6.12 FIRE PROTECTION FUNCTION

Two external ﬁre alarms can be connected to the unit to stop it in

case of ﬁre by using universal analogue inputs. Smoke detectors

and ﬁre dampers cannot be connected directly to the air handling

unit, a separate ﬁre system is needed.

Several functions which are activated if ﬁre alarm is triggered

can be implemented. Therefor the fan speeds can be set inde-

pendently or completely stopped if needed.

6.13 SUMMARY ALARM

There are two separate alarm outputs for indicating A- and

B-alarms. Both can be connected as either NO or NC potential

free contacts.

6.15 7" HMI CONNECTION

6.14 UNIT OPERATION ON/OFF INDICATION

STARTING THE UNIT

When the electrical connections are made and all the accesso-

ries are mounted the unit is ready to start up.

1. Turn the safety switch to 1 (ON).

2. Start the unit (see chapter 8).

DAMPERS

Check that all dampers opens and closes correctly.

VALVE ACTUATORS

Check that valve actuators for heating and cooling works correctly.

AIR FLOW MEASUREMENT

The eCO Side has measuring nipples for air ﬂow measurement.

Using a measuring pressure Dpm (Pa) and a constant (k) the air

ﬂow q

at 20 °C can be calculated using the following equation:

NOTE! When the unit is supplied with

Constant Air Volume Control there will be

no measuring nipples on top of the unit.

TEMPERATURE CORRECTION

The air ﬂow formula above applies to air with a temperature of

+20 °C. At other air temperatures the air ﬂow must be corrected

using the formula:

The value of the constant (k) is shown in the table below.

= 1000

Size 03 04 06

k-value air fan 58.4 51.5 49.2

The measuring pressure, Dpm, is the difference between the

pressure in the empty section at the fan inlet and the pressure

inside the inlet cone. A manometer (RDTZ-56) can be connected

to view the measuring pressure. This is used as a reference for

monitoring the unit. Connect hoses with 4 mm diameter between

the nipples on the top of the unit and the manometer, see Fig. 1.

If the unit is supplied with Constant Air Volume control the air

ﬂow can be read in the control panel.

8.1 GENERAL

HMI

This section introduces the touchscreen control panel and the

web conﬁgurator, also known as the ‘Human Machine Interface’,

or simply HMI.

The HMI serves two main purposes: To provide information about

the current operational state of the unit. To allow the unit to be

setup and conﬁgured.

TOUCH SCREEN TIPS

To select an item, touch the centre of the icon or option. Do not

press too hard, the touch screen is sensitive enough to pick up

light, ﬁrm touches. Use the tip of your ﬁnger or the back of a pen-

cil to touch the required option. Be careful not to touch any other

options.

CLEANING THE SCREEN

Disconnect the power cord (this is in most cases the ethernet

which provides PoE). Gently wipe the screen with a soft, dry

non-abrasive cloth. If the marks remain, moisten the cloth slightly

with a detergent that is designed for touchscreens and wipe the

screen gently from top to bottom. Never use other detergents, as

8. CONTROL PANEL, OPERATIONS, COMMISSIONING

Bypass current proﬁle for a certain number of minutes by another

proﬁle.

Change conﬁguration of proﬁles. Unit needs a switch of proﬁle

before applying changes to current operating proﬁle.

The home screen will always contain at least 3x3 tiles. If the

conﬁguration doesn’t include enough settings this tile will be used

as a placeholder.

CHANGING CONTROL TILE VALUES

To change the basic settings mentioned above there can be two

different ways. Press a control tile and one of the following menus

show up.

Setpoints are changed by using the control wheel, which can

easily be dragged to the desired value. Also, the up and down

arrows allow accurate setting by predeﬁned steps. The amount

of each step depends on the control value that is edited (e.g. air

volume ﬂow steps are 100 m³/h, regarding this is the determined

unit for air volume ﬂow).

Control types are changed by using an option dialog, from which

the user can choose a preconﬁgured number of behaviours.

USING AUXILIARY TILES

Auxiliary tiles do not allow individual changes to the current

operation of the unit but most of them have a temporary or

permanent effect on its behaviour.

Proﬁle bypass Allows to run another proﬁle for up to 60 min

(5 min steps) and switching automatically back

to time scheduled proﬁle afterwards.
