Operation
–
Off
: the built-in plate heat exchanger in the
heating appliance is not kept constantly
hot (eco mode); as a result energy is saved.
In eco mode, the hot tap has to be run for
a short while before the water becomes
hot.
•
If the DHW cylinder and FR 100 are directly
connected to the heating appliance, the DHW
program switches between the following
operating modes:
–
On
: Cylinder heating enabled (temperature
in accordance with setting on heating
appliance).
–
Off
: Cylinder heating blocked.
•
With appliances connected to a DHW cylinder
and FR 110, the DHW program specifies the
required water temperature (set
temperature).
–
If the temperature measured in the DHW
cylinder is below the set temperature, the
cylinder is reheated.
–
Once the set temperature is reached (or
exceeded), cylinder reheating is stopped.
DHW circulation program
The DHW circulation program specifies when a
connected DHW circulation pump for domestic
hot water runs.
5.2 Setting programs
5.2.1 Display views and menu navigation
The user interface of the FR 100 / FR 110 room
temperature-dependent heating controller is
implemented as a so-called "menu". Within that
menu, the various functions are arranged in a
hierarchical structure. For greater clarity, the
menu is subdivided into three sections (
MAIN
MENU
,
INFO
,
INSTALLER SETTINGS
). Each
section can be accessed by its own button. The
entire menu structure is shown in tabular form in
chapters 6.1, 7 and 8.1.
To navigate through the menu:
•
Press
to
open
MAIN MENU
. From any
point within the
MAIN MENU
, press
to
go back to the standard display.
•
Press
to open the
INFO
menu. From any
point within the
INFO
menu, press
to go
back to the standard display.
•
Hold down
for at least 3 seconds to open
the
INSTALLER SETTINGS
menu. From any
point within the
INSTALLER SETTINGS
menu,
press
to go back to the standard display.
•
The selected menu point/parameter is
displayed in
colours, i.e. white on
black.
•
Arrows in the left margin indicate that there is
more information than can be shown on the
display at once. It can be viewed with
.
•
opens the submenu associated with the
selected menu point/parameter or activates
editing mode for the parameter (the
parameter setting starts flashing).
If the DHW program changes from a
higher to a lower temperature, the
water in the cylinder will not
immediately cool to the lower
temperature, i.e. water at a higher
temperature will continue to be
available for some time. However,
the cylinder will not be reheated
until the temperature falls below
the new set temperature.
The functions of the controls and the
meanings of the symbols on the
display are explained on pages 2
and 3.
