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. See

"Selecting weather dependent set point operation (only in heating
mode)" on page 6

 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 sanitary water tank.

The disinfection function disinfects the sanitary water tank by
periodically heating the sanitary water to a specific temperature.

[2-00] Operation interval: day(s) of the week at which the
sanitary 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 sanitary 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.

NOTE

Before shipping, the set values have been set as
shown under 

"Field settings table" on page 15

.

When exiting FIELD SET MODE, "

" may be

displayed on the user interface LCD while the unit
initialises itself.
