8.6. Powering up the indoor unit
When power supply to the indoor 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.
8.7. Setting the pump speed
The pump speed can be selected on the pump (see
components in the unit" on page
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 medium speed (II) or low speed (III).
The available external static pressure (ESP, expressed in kPa) in
function of the water flow (l/min) is shown in the graph below.

8.8. 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
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 in chapter
