Field Settings - Rotex RDLQ011AA6V3 Mode D'emploi

Failure diagnosis at the moment of first installation
In case nothing is displayed on the remote controller (the current
set temperature does not display), check for any of the following
abnormalities before you can diagnose possible malfunction
codes.
Disconnection or wiring error (between power supply and unit
and between unit and remote controller).
The fuse on the PCB may have run out.
If the remote controller shows " E3 ", " E4 " or " L8 " as an error code,
there is a possibility that either the stop valves are closed, or that
air inlet or air outlet are blocked.
If the error code " U2 " is displayed on the remote controller, check
for voltage imbalance.
If the error code "L4" is displayed on the remote controller, it is
possible that air inlet or air outlet are blocked.
The reversed phase protection detector of this product only
works during the initialisation stage after a power reset.
The reversed phase protection detector is designed to stop the
product in case of an abnormality when the product is started
up.
When the reversed phase protection circuit forced the unit to
stop, check if all phases are existing. If this is the case, shut
off the power supply to the unit and replace two of three
phases. Turn on power again and start the unit.
Reversed phase detection is not performed while the product
is operating.
In case of possible reversal of phases after a momentary
black out of power and the power goes on and off while the
product is operating, install a reversed phase protection
circuit on site. Such situation is not unimaginable when using
generators. Running the product in reversed phase can
break the compressor and other parts.
For a missing phase in case of W1 units, " E7 " or " U2 " will be
displayed on the remote controller of the unit.
Operation will be impossible with either one of these
phenomena. If this happens, turn off the power, re-check the
wiring and switch the position of two of the three electrical wires.
Installation manual

Field settings

The unit should be configured by the installer to match the installation
environment (outdoor climate, installed options, etc.) and user
demand. Thereto, a number of so called field settings are available.
These field settings are accessible and programmable through the
user interface.
Each field setting is assigned a 3-digit number or code, for example
[5-03], which is indicated on the user interface display. The first digit
[5] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given under "Field
settings table" on page 27. In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of each field setting is given under "Detailed
description" on page 22.

setting first code.
Press the bgj button to select the appropriate field
3
setting second code.
4 Press the pfi button and pfj button to change

required.
When finished, press the z button to exit FIELD SET MODE.

NOTE Changes made to a specific field setting are only
stored when the pr button is pressed. Navigating to a
new field setting code or pressing the z button will
discard the change made.
NOTE Before shipping, the set values have been set as
shown under "Field settings table" on page 27.
When exiting FIELD SET MODE, "88" may be
displayed on the user interface LCD while the unit
initialises itself.
