Disclaimer

Danger/Warning/Caution

• All sta concerned shall acquaint themselves with

these instructions before beginning any work on the
unit. Any damages to the unit or its components
caused by improper handling or misuse by the
purchaser or the installer cannot be considered
subject to guarantee if these instructions have not
been followed correctly.

• Make sure that the power supply to the unit is

disconnected before performing any maintenance or
electrical work!

• All electrical connections must be carried out by an

authorized installer and in accordance with local
rules and controls.

• Although the mains supply to the unit has been

disconnected there is still risk for injury due to
rotating parts that have not come to a complete
standstill.

• Beware of sharp edges during mounting and

maintenance. Make sure that a proper liing device
is used. Use protective clothing.

• Unit should always be operated with closed doors

and panels.

• If the unit is installed in a cold place make sure that

all joints are covered with insulation and are well
taped.

• Duct connections /duct ends should be covered

during storage and installation, in order to avoid
condensation inside of the unit.

• Check that there are no foreign objects in unit,

ducting system or functional sections.

• The unit is packed to prevent damage of the

external and internal parts of the unit, dust and
moisture penetration. If the unit is not to be installed
immediately, it should be stored in a clean, dry
area. If stored externally, it should be adequately
protected from the weather inuence.

RANGE OF APPLICATION

The GLOBAL units are designed for use in comfort
ventilation applications.

Depending on the variant selected, GLOBAL units can be
utilised in buildings such as oce buildings, schools, day
nurseries,public buildings, shops, residential buildings, etc.

GLOBAL units equipped with plate heat exchangers (PX)
can also be used for the ventilation of moderately humid
buildings; however not where the humidity is continuously
high, such as in indoor swimming baths, saunas, spas or
wellness centres.

Please do contact us if you have a need for a unit that is
suited for such an application.

HOW TO READ THIS DOCUMENT

Please make sure that you have read and understood the
safety precautions below.

Please read chapter 2 where the Symbols and
Abbreviations used for GLOBAL are listed and Chapter 5
where the operating principles of a GLOBAL air handling
unit are described. The commissioning of the unit is
described in chapter 6.

The commissioning chapter is divided based on what
device (Remote Control, Graphical Remote Control or
App) is used to control the unit. Simply go to the sub
chapter, relevant for your device and the base setup for
the operating mode which will be used to control the
unit.

4.1 CIRCUIT BOARD SAT 3  CID372005

The SAT3 circuit board is used for extra functions for
which inputs and outputs are not included as standard
in the control unit of the air handling unit. All outputs
are normally open (N.O.). Maximal load: 230VAC – 4A.
The circuit board SAT3 allows for signalling of the
following by means of a potential-free contact:

• Fan status - O.R. 1

• Dierential pressure alarm - O.R. 2

• Heating demand - O.R.3

• Bypass status - O.R.4

Installation

SAT3 must be plugged onto the control board circuit
(see g.1).

Attention: The SAT3 must be plugged in before
the circuit is powered. SAT must be plugged in
correctly, wrong positioning can damage both
circuits permanently.

Fig. 3

4.2 CIRCUIT BOARD SAT BA/KW  CID372004

SAT TAC5 BA/KW is a satellite circuit designed to be tted on the main
control board. It permits control of external coils.

Installation

The SAT BA/KW must be plugged onto the control board circuit
(se e Fig.2).

Attention: The SAT TAC5 BA /KW must be plugged in before
the circuit is powered. SAT must be plugged in correctly, wrong
positioning can damage both circuits permanently.

Wiring

The terminals of the SAT BA/KW are displayed in g.3

WP WP = Cooling demand (max. 30 V-2 A)

5.1 OPERATING MODE

There are ve main operating modes. The operating
mode determines how the airow or the fan torque
is modulated. The default operating mode is Airow
control. Exceptions are units equipped with backwards
fans without the Constant Air Kit or if Constant Torque
mode has been selected in the product setup menu, in
both cases it is the fan torque that will be controlled and
modulated.

5.0 Functions

In all the operating modes, the supply fan(s) will operate
as per the assigned mode and parameters. The exhaust
fan(s) will operate according to the chosen percentage
of the supply fan (%EXH/SUP ratio). The ve main
operating modes are:

• 1 - Airow control:

Flow control involves operating the air handling unit to keep the pre-set airow constant. The speed of the
fans is automatically regulated to provide correct airow even if the lters begin to become clogged, air
terminals are blocked, etc. Airow control mode is advantageous, since the airow always is exactly as it was
from the beginning. It should however be noted that everything that increases the pressure drop in the
ventilation system, such as blocking of air terminals and dust accumulating in lters, causes the fans to run at
a higher speed. This results in higher power consumption and may also cause discomfort in the form of noise.
There are three airow setpoints to be congured by the user (m³h K1, m³h K2, m³h K3).

• 2 - Torque control:

3 torque setpoints to be congured by the user (%TQ K1, %TQ K2, %TQ K3). The setpoint is congured
in % of the maximal torque. The torque control allows to vary the fan speed automatically, to
provide a variable airow for demand controlled systems (DCV). This allows for demand controlled fan operation
or fan optimisation by a BMS system, mostly used in multi zone systems. This operation mode can partially
replace the constant pressure control when a duct pressure sensor hasn’t been installed.

• 3 - Demand control 0-10V:

The airow is controlled by a 0-10 V signal. The control signal is connected to terminals K2&GND. The assigned
supply airow is set as a percentage of a linear 0-10 V signal. The user denes the link with 4 parameters: Vmin,
Vmax, m³h Vmin and m³h Vmax, applied to the following diagram. The demand control mode is also
available for modulating fan torque instead of airow (relevant for backwards fans units without Kit CA).
The principle is identical to the demand control mode operation with the dierence that Vmin and Vmax are
connected to a %TQ instead of m³/h.

• 4 - Pressure control:

The airow automatically varies to provide constant pressure in the ducting system. This type of control is
also called VAV control (Variable Air Volume).

Pressure on supply: the airow of the supply fan(s) is modulated to maintain a certain pressure Setting
constant. The pressure is measured by a pressure sensor located in the supply air duct.
Pressure on exhaust: the airow of the exhaust fan(s) is modulated to maintain a certain pressure Setting
constant. The pressure is measured by a pressure sensor located in the extract air duct.

• 5 - MODE OFF :

This stops the AHU
