4P487293-1 – 2017.08
NOTICE
This function is NOT possible when there is direct duct
connection.
8.5.10
About the electrical heater operation
If the electrical heater is used, put setting 19(29)‑8 on 03 or 04 and
setting 18(28)‑9 on 01. For more details, see the printed circuit board
heater manual.
8.5.11
About external linkage input
Terminals J2 and JC function as contact signal input to switch the
heat reclaim ventilation unit on or off.
8.5.12
About filter contamination check
The filter contamination check can ONLY be done in the same
conditions as 19(29)‑0‑04 or 05. For example if the unit is working in
bypass it CANNOT be checked. In this case a timer is counting the
hours. After a target value is reached, the conditions are changed for
a short time to be able to do the filter contamination check.
With setting 18(28)‑11‑02: this timer can be set to 0.
With setting 18(28)‑11‑03: it can be chosen to do the filter
contamination check at this moment.
After finishing 18(28)‑11‑02 and 03, the setting is put back
automatically to 18(28)‑11‑01 and the unit operation is continued as
before. The setting can ONLY be done when setting 19(29)‑0‑01 or
02 is used.
INFORMATION
This function is NOT possible in case of errors.

Commissioning
9.1
Overview: Commissioning
After installation and once the field settings are defined, the installer
is obliged to verify correct operation. Therefore a test run MUST be
performed according to the procedures described below.
This chapter describes what you have to do and know to
commission the system after it is configured.
Commissioning typically consists of the following stages:
1
Checking the "Checklist before commissioning".
2
Performing a test run.
3
If necessary, correcting errors after abnormal completion of the
test run.
4
Operating the system.
9.2
Precautions when commissioning
DANGER: RISK OF ELECTROCUTION
CAUTION
Do NOT perform the test operation while working on
the indoor units, the outdoor unit or the heat reclaim
ventilation units.
When performing the test operation, NOT only the unit to
which the user interface is connected will operate, but all
the units that are linked to this one as well. Working on an
indoor unit or the heat reclaim ventilation unit while
performing a test operation is dangerous.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it will
cause injury.
9.3
Checklist before commissioning
After the installation of the unit, first check the following items. Once
all below checks are fulfilled, the unit MUST be closed, ONLY then
can the unit be powered up.
You read the complete installation and operation
instructions, as described in the
installer and user
reference guide
.
Installation
Check that the unit is properly installed, to avoid abnormal
noises and vibrations when starting up the unit.
Field wiring
Be sure that the field wiring has been carried out
according to the instructions described in the chapter
"6.5 Electrical wiring" on page 15
, according to the wiring
diagrams and according to the applicable legislation.
Power supply voltage
Check the power supply voltage on the local supply panel.
The voltage MUST correspond to the voltage on the
identification label of the unit.
Earth wiring
Be sure that the earth wires have been connected
properly and that the earth terminals are tightened.
Insulation test of the main power circuit
Using a megatester for 500 V, check that the insulation
resistance of 2 MΩ or more is attained by applying a
voltage of 500 V DC between power terminals and earth.
NEVER use the megatester for the transmission wiring.
Fuses, circuit breakers, or protection devices
Check that the fuses, circuit breakers, or the locally
installed protection devices are of the size and type
specified in the chapter
"5.4 Preparing the electrical
wiring" on page 11
. Be sure that neither a fuse nor a
protection device has been bypassed.
Internal wiring
Visually check the electrical component box and the
inside of the unit on loose connections or damaged
electrical components.
Air inlet/outlet
Check that the air inlet and outlet of the unit is NOT
obstructed by paper sheets, cardboard, or any other
material.
Installation date and field setting
Be sure to keep record of the installation date on the
sticker on the rear of the front panel according to
EN60335‑2‑40 and keep record of the contents of the field
setting(s).
9.4
Checklist during commissioning
To perform a
test run
.
9.4.1
About the test run
After completing the installation of the system, turn on the power of
the heat reclaim ventilation units. Refer to the manual of the user
interface of each unit (user interface for air conditioner, central
control unit, etc.) for conducting a trial operation.
