Powering Up The Unit; Setting The Pump Speed; Field Settings - Daikin EDLQ036BA6VJU1 Manuel D'installation

Powering up the unit

When power supply to the unit is turned on, "88" is displayed on the
user interface during its initialisation, which might take up to 30
seconds. During this process the user interface cannot be operated.

Setting the pump speed

The pump speed can be selected on the pump (see "Main
components" on page 12).
The default setting is high speed (I). If the water flow in the system is
too high (e.g., noise of running water in the installation) the speed
can be set to low speed (II).
NOTE The speed dial on the pump indicates 3 speed
settings. However, only 2 speed settings exist: low
speed and high speed. The indicated medium speed
setting on the speed dial is equal to low speed.
The available external static pressure (ESP, expressed in psi (kPa)) in
function of the water flow ((gallons/min) (l/min)) is shown in the graph
below.

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.

Field settings

The unit shall 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 35. 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 26.
Procedure
To change one or more field settings, proceed as follows.
Temperature values displayed on the digital controller
(user interface) are in °C.
