The detailed system scheme for installing the
hydraulic components and the associated control
devices can be found in the technical guides or
tender specifications.
3.1 Installation
3.1.1 Fitting the heating controller
The control quality of the controller is dependent
on where it is installed.
The installation location (= lead room) must be
suitable for controlling the associated heating
circuits.
BSelect the installation location.
Fig. 5
BRemove the top section and slide cover from
the base.
Fig. 6
BFit the base.
Fig. 7
BMake the electrical connections (ÆFig. 11 on
page 17 or 9 on page 16).
DANGER: Risk of electric shock!
BPrior to the installation of this
accessory:
Isolate the heating appliance and
all other BUS subscribers from the
power supply (220 to 240 V AC).

3.2 Electrical connections
BUse electrical cable according to local codes
and requirements.
BRoute all LV cables/leads separately from
cables carrying 220 to 240 V or 380 to 415 V
to avoid inductive interference (minimum
separation 100 mm).
BIn case of external inductive interference,
shield the cables.
This ensures that the cables are shielded from
external interference (e.g. heavy current
cables, overhead wires, transformer stations,
radio and television set, amateur radio
stations, microwave ovens etc).
3.2.1 Connecting the BUS link
Permissible lead lengths from the BUS-enabled
Heatronic 3 to the controller:
BConnect the controller to a heating appliance
with BUS-enabled Heatronic 3.

how the heating appliance and controller
work and how to operate them.
–Inform the user about the assigned heating
circuits, e.g. heating circuit 1 is for the
radiator heating system and heating circuit
2 for the underfloor heating system.
–Explain to the user how to operate the
system on a day-to-day basis, e.g. time,
operating modes for the heating circuits,
DHW temperature, time programs for
heating circuits and DHW.
–Explain how to use the thermal disinfection
function and the associated risk of
scalding.

Introduction
With the FR 100 / FR 110 heating controller, you
can automatically control the room and DHW
temperatures with a heating and DHW program
created according to your own individual
requirements.
Fig. 12 Example of heating program
Once the controller is set to your personal
preferences, you hardly need the menus for
“everyday use”. Nevertheless, it is useful to be
familiar with basic navigation through the menus.
Therefore, you should read the whole of the
following sections 5.1 and 5.2 below and adjust a
heating or DHW program to your own
requirements as described in chapter 5.2.2.
Why not take the trouble – it will be worth your
while! The procedure for changing a switching
point will illustrate everything you need to know
about navigating through the menus and entering
settings. You can then make all other settings in
the same way with the aid of the information in
chapters 6 and 8.
The description of the menus reflects the
arrangement of the menu points in the heating
controller. The tables in chapters 6.1, 7 and 8.1
show the entire menu structure. They also
provide details of the setting ranges and factory
settings for all adjustable parameters. More
information on the menu points can be found in
sections 6.2 to 6.5 for the user level, and
sections 8.2 to 8.8 for the contractor level.
The description of a menu points starts with its
menu path. That shows you how to reach the
menu point concerned by navigating through the
menus. The individual menu levels are separated
by symbol > , e.g. holiday > start.
Some menu points are dependent on others. In
such cases, a page reference directs you to a
description of the menu point on which it
depends. Make use of such page references to
other menu points. They will help you to
understand associated functions.
If the FR 100 is connected to the
heating appliance via the analogue
connection (1-2-4 interface), only
the heating program, the
parameters for central heating and
the controller-specific settings
(e.g. Time) are active. DHW, solar
and system-specific settings
(e.g. System info) are not available.
In this case, DHW can be switched
directly via the heating appliance.

The controller provides the option
of setting the required room
temperature for the operating mode
concerned.
