For a summary of all field settings refer to "6.1.1. Field settings table"
on page 39.
[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] 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 in 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
"[9] Automatic temperature compensation" on page 21 for
compensation values for leaving water temperature.
■ [0-02] Setting not applicable
■ [0-03] Status: defines whether the ON/OFF instruction can be
used in the schedule timer for space heating.
Refer to the operation manual for details how to program the
schedule timer.
The schedule timer for space heating can be programmed in
2 different ways: based on the temperature set point (both
leaving water temperature and room temperature) and based on
the ON/OFF instruction.
In the following tables both methods on how to interpret the schedule
timer are shown.
Operation example: Schedule timer based on temperature set
points.
When setback function (refer to "[2] Automatic setback function" on
page 19) is enabled, the setback operation will have priority over the
scheduled action in the schedule timer.
