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 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.

4.1 DIGITAL OUTPUTS
The digital outputs DO7 to DO11 may be used to activate a
relay (1 N/O contact. Input voltage: 24 V DC). See gure 1 for
example with DO7.: output for heat circulator pump, gure 2
for DO9: output for alarm indication, gure 3 for DO10pressure
alarm indication. Same principle for DO8 and DO11.

4.2 PRESSURE SWITCHES
In application where pressure switches are used, follow gure
4 wiring, with pressure switch for supply lter connected on X4
and the exhaust one on X2.
N.B.: connectors X2/X4 may be ordered separetely
(CID522223) if other pressure switches are used instead of the
ones in the dedicated kit CID360025.

4.3 CIRCUIT BOARD SAT IO  CID3 72 144
SAT IO is a satellite circuit designed to be tted on the main control
board. It permits to extend the number of inputs and outputs.
Installation
The SAT IO must be plugged onto the control board circuit (see Fig.5).
Attention: The SAT IO must be plugged in before the circuit is
powered. SAT must be plugged in correctly, wrong positioning can
damage both circuits permanently.

4.4 EXTERNAL COILS CONTROL
In case of addition of external coil, the kit EBA or KWext will be necessary to connect respectively the EBA (external
hydraulic/evaporation/condensation battery) or KWext (external electrical coil) to the control board TAC. Both kits
consist simply in extender cable, anyway necessary to reach the external battery, connectorized at the control board
side extremity.
