Detailed description
[0] Remote control setup
■
[0-00]
User permission level
The remote controller can be programmed to make certain
buttons and functions unavailable for the user. There are 2
permission levels defined. Both levels (level 2 and level 3) are
basically the same, the only difference is that for level 3 no water
temperature settings are possible (see table below).
By default no level is defined so all buttons and functions are
operable.
The actual permission level is determined by field setting. For
permission level 2, set field setting [0-00] is to 2, for permission
level 3, set field setting [0-00] to 3.
Once the field setting is set, the chosen permission level is not
yet active. Enabling the selected permission level is done by
simultaneously pressing buttons
and
immediately
followed by simultaneously pressing buttons
and
, and
keeping all 4 buttons pressed for at least 5 seconds. Note that
no indication on the remote controller is given. After the
procedure the blocked buttons will not be available anymore.
Deactivating the selected permission level is done on the same
way.
■
[0-01]
Room temperature compensation value
If needed, it is possible to adjust some thermistor value of the
unit by a correction value. This can be used as countermeasure
for thermistor tolerances or capacity shortage.
The compensated temperature (= measured temperature plus
compensation value) is then used for controlling the system and
will be displayed in the temperature read-out mode. See also
Automatic temperature compensation" on page
for
compensation values for leaving water temperature and
domestic hot water temperature.
■
[0-03]
Status: defines whether the ON/OFF instruction can be
used in the schedule timer for space heating.
The schedule timer for space heating can be programmed on 2
different ways: based on the temperature set point (both leaving
water temperature and room temperature) and based on the
ON/OFF instruction.
NOTE
■
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.
■
The field settings are grouped by their field setting
first code.
For example field settings [0-00], [0-01], [0-02]
and [0-03] are defined as group "0".
When different values are changed within the
same group, pressing the
button will save all
the values changed within this group.
Be aware of this when changing field settings
within the same group and pressing the
button.
NOTE
■
Before shipping, the set values have been set as
shown under
"Field settings table" on page 32
.
■
When exiting FIELD SET MODE, "
88
" may be
displayed on the remote controller LCD while the
unit initializes itself.
When running through the field settings you may notice
that there are some more field settings as there are
mentioned in the
"Field settings table" on page 32
These
field settings are not applicable and may not be
changed

NOTE
By default space heating based on temperature set
point (method 1) is enabled, so only temperature shifts
are possible (no ON/OFF instruction).
Advantage of this method is that you can simply switch
off the space heating operation by pushing the
button without disabling the automatic domestic hot
water storage operation (e.g. during summertime when
no space heating is required).
