[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. 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.

[2] Disinfection function
Applies only to installations with a domestic hot water tank.
The disinfection function disinfects the domestic hot water tank by
periodically heating the domestic water to a specific temperature.
The disinfection function field settings must be configured
by the installer according to national and local regulations.
[2-00] Operation interval: day(s) of the week at which the
domestic water should be heated.
[2-01] Status: defines whether the disinfection function is
turned on (1) or off (0).
[2-02] Start time: time of the day at which the domestic water
should be heated.
[2-03] Set point: high water temperature to be reached.
[2-04] Interval: time period defining how long the set point
temperature should be maintained.

[3] Auto restart
When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
supply failure.
NOTE It is therefore recommended to leave the auto restart
function enabled.
Note that with the function disabled the schedule timer will not be
activated when power returns to the unit after a power supply failure.
Press the pr button to enable the schedule timer again.
[3-00] Status: defines whether the auto restart function is
turned ON (0) or OFF (1).
NOTE If the benefit kWh rate power supply is of the type that
power supply is interrupted, then always allow the auto
restart function.
