Setting The Pump Speed; Field Settings - Daikin EKHBX030BA Installation Manual

Setting the pump speed

The pump speed can be selected on the pump (see "Main
components" on page 10).
The default setting is high speed (III). 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 medium speed (II) or low speed (I).
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.

Field settings

The indoor 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 on the indoor unit.
Each field setting is assigned a 3-digit number or code, for example
[1-03], which is indicated on the user interface display. The first digit
[1] 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.
