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 s and ba, 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.
■ [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.
NOTICE
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.
NOTICE
■ Before shipping, the set values have been set as
shown under "Field settings table" on page 15.
■ When exiting FIELD SET MODE, "88" may be
displayed on the user interface LCD while the unit
initialises itself.
