Installation manual

13.9. 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 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
"13.10. Field settings table" on page 40. 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 31.

Detailed description

[0] User permission level

If required, certain user interface buttons can be made unavailable for
the user.

Three permission levels are defined (see the table below). Switching
between level 1 and level 2/3 is done by simultaneously pressing
buttons

pfi

and

pfj

immediately followed by

simultaneously pressing buttons

and

, and keeping all 4

buttons pressed for at least 5 seconds (in normal mode). Note that no
indication on the user interface is given. When level 2/3 is selected,
the actual permission level – either level 2 or level 3 – is determined
by the field setting [0-00].

[1] Weather dependent set point (heating operation only)

The weather dependent set point field settings define the parameters
for the weather dependent operation of the unit. When weather
dependent operation is active the water temperature is determined
automatically depending on the outdoor temperature: colder outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift up
or down the target water temperature by a maximum of 5°C. See the
operation manual for more details on weather dependent operation.

■

[1-00] Low ambient temperature (Lo_A): low outdoor
temperature.

■

[1-01] High ambient temperature (Hi_A): high outdoor
temperature.

■

[1-02] Set point at low ambient temperature (Lo_Ti): the
target outgoing water temperature when the outdoor
temperature equals or drops below the low ambient
temperature (Lo_A).
Note that the Lo_Ti value should be higher than Hi_Ti, as for
colder outdoor temperatures (i.e. Lo_A) warmer water is
required.

■

[1-03] Set point at high ambient temperature (Hi_Ti): the
target outgoing water temperature when the outdoor
temperature equals or rises above the high ambient
temperature (Hi_A).
Note that the Hi_Ti value should be lower than Lo_Ti, as for
warmer outdoor temperatures (i.e. Hi_A) less warm water
suffices.

Changes made to a specific field setting are only stored
when the

button is pressed. Navigating to a new field

setting code or pressing the

button will discard the

change made.
