3.2
Electrical connections
Connection via BUS interface or
1-2-4 interface:
B To achieve as even a radiator
temperature as possible,
connect the controller via the
2-wire BUS.
The flow temperature is only
heated to a level that allows the
required room temperature to be
reached. This demanddependent flow temperature
control is achieved through
longer pump run-on times,
allowing as low a flow
temperature as possible, and
therefore energy saving
operation. This type of control
offers the full range of setting
options and displayed
information.
B To reduce the pump run-on time,
connect the controller via
1-2-4 interface.
Through the output control, the
boiler reacts quickly to changes
in room temperature. This type
of control reduces the range of
setting options and displayed
information. This classic type of
control is highly suitable for
combi boilers in apartments, for
example, because the displays in
these systems are extremely
convenient.
B In 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).

Operation
Introduction
With the FR 120 heating controller, you can
automatically control the room and DHW
temperatures with a heating and DHW program
created according to your own individual
requirements.
[°C]
[t]
6 720 612 481-70.1J
Fig. 12
Example of heating program
If the FR 120 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.
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.
The functions of the controls and the
meanings of the symbols on the
display are explained on pages 2
and 3.
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 .
6 720 800 817 (2012/02)
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 menu structure in chapter 6.1 and
the tables in chapters 7 and 8.1 show the entire
menu tree. 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.
The controller provides the option
of setting the required room
temperature for the operating mode
concerned.

5.1
Heating and DHW programs
5.1.1 General
Heating program
The programs for heating and DHW enable you to
achieve maximum energy savings while still
enjoying optimum comfort in terms of room
temperature and availability of hot water. That is
achieved, for instance, by deactivating DHW
heating at times when nobody requires hot
water.
The heating program regulates the heating
operation. There are three modes for heating
operation:
5.1.2 7-day program
The time program is set up so it repeats every
seven days. The program memory can store 6
switching times per day, i.e. a total of up to 42
switching times.
To simplify programming, you can set switching
times for groups of days as well as for individual
days.
•
Comfort
•
Economy
•
Frost (frost protection)
For each of these operating modes, there is a set
room temperature stored in the heating
controller (Æ chapter 5.6.1, page 27).
DHW program
The DHW program acts differently, subject to the
method of DHW heating:
•
The following groups of days are offered:
•
All days
•
Mon - Fri
•
Sat + Sun
– On: if the eco button on the heating
appliance is not lit, hot water is available
very quickly on demand (comfort mode).
– 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, for example, you change and save a switching
time for menu point Mon - Fri, that change is
simultaneously applied to every day from
Monday to Friday.
5.1.3 Structure of programs
Programs for heating and DHW are always
structured in the same way. Up to six switching
points (switching times) can be specified. A
change of operating mode is specified for each
switching time. The specified operating mode
applies until changed by the next switching time.
With combi boilers (boilers which produce hot
water instantaneously on demand), the DHW
program switches between the following
operating modes:
•
With boilers connected to a domestic hot
water cylinder, the hot water programme
specifies the desired water temperature
(specified 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.
6 720 800 817 (2012/02)
20 | Operation
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.
DHW circulation program
The DHW circulation program specifies when a
connected DHW circulation pump for domestic
hot water runs.
6 720 800 817 (2012/02)
5.2
Display views and menu
navigation
The user interface of the FR 120 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 menu to open MAIN MENU. From any
point within the MAIN MENU, press menu to
go back to the standard display.
•
Press info to open the INFO menu. From any
point within the INFO menu, press info to go
back to the standard display.
•
Hold down menu for at least 3 seconds to open
the INSTALLER SETTINGS menu. From any
point within the INSTALLER SETTINGS menu,
press menu to go back to the standard display.
•
The selected menu point/parameter is

Solar settings
Main menu: Solar
Solar optimisation
Use this menu if you want to limit the cylinder
temperature or optimise the set DHW and flow
temperatures based on the available solar energy
in your geographical region.
In order to use as much solar energy as possible,
the FR 120 heating controller can estimate the
expected solar yield over the course of a day and
take it into account when controlling the DHW.
The heating appliance will then not be required
to produce as much heat and will use less gas.
Limiting cylinder temperature
In order to store as much solar energy as
possible, a high cylinder temperature is required.
Limiting the cylinder temperature prevents
overheating of the domestic hot water. The
temperature setting is transmitted by the ISM
module during commissioning.
WARNING: Risk of scalding!
If the cylinder temperature is
higher than 60 °C.
B If the cylinder temperature limit
is set to > 60 °C, install a
thermostatic DHW mixer or the
DHW comfort assembly (WWKG,
accessories Æ Fig. 4 on
page 11) in the DHW line.
B Set the DHW mixer unit to 60 °C
max.
•
T2: Max. solar cylinder temperature: Cylinder
temperature > 60 °C in DHW cylinders only if
outlet temperature is limited by thermostatic
DHW mixer.

Æ chapter 8.5.3 on page 49
•
Optimizing influence DHW: Maximum
reduction of set DHW temperature by effect of
solar thermal system.
Example:
– Set DHW temperature = 60 °C
– Optimizing influence DHW = 15 K
– Set DHW temperature for heating
appliance = 60 °C – 15 K
– Provided there is sufficient solar output
available, the maximum reduction is set
and the heating appliance heats the DHW
to 45 °C, with the remaining 15 K being
provided by the solar contribution.
Optimizing influence DHW does not
start until a calibration phase of at
least 30 days has been completed
after commissioning of the solar
thermal system. In that period, the
FR 120 heating controller “learns”
what level of solar yield is possible.

so, it is guided by the heating times
required on previous days. In that way the
controller is able to take account of
seasonal outside temperature fluctuations.
While the modes Economy

are active, the conditions must remain
constant for the lead room:
Keep the same doors closed.
Keep windows closed wherever possible.
Heat the same rooms.

•
Calibrate room temperature sensor:
– Fit a suitable precision instrument near or
FR 120. The precision instrument must not
transfer any heat to the FR 120.
– Keep away from heat sources such as
sunlight, body heat, etc. for 1 hour.
– Adjust the displayed room temperature
correction value.
•
Adjustment factor I
The Adjustment factor I is the rate at which a
constant room temperature control deviation
is corrected.
– ≤ 40 %: Set a lower factor to achieve
minimal room temperature overshoot by
more gradual correction.
– ≥ 40 %: Set a higher factor to achieve
faster correction by a greater room
temperature overshoot.
•
Amplification factor V:
Subject to changes in room temperature, the
Amplification factor V influences the heat
demand.
– ≤ 80 %: Set a lower factor to reduce the
influence on the heat demand. The
selected room temperature is reached
more slowly with only minimal overshoot.
– ≥ 80 %: Set a higher factor to increase the
influence on the heat demand. The
selected room temperature is reached
quickly with a tendency to overshoot.

58 | Energy saving tips
10 Energy saving tips
•
The temperature in the lead room (where the
controller is fitted) acts as a guide for the
heating circuit to which the controller is
assigned. Therefore, set the output of the
radiators inside the lead room as low as
possible:
as the heating system stays off.In that case set
the switching point for Economy to an earlier
time.
•
Don't keep windows slightly open for
ventilation. This leads to a constant extraction
of heat from the room without noticeably
improving the ambient air in the room.
•
Vent briefly but intensively (open window
fully).
•
When ventilating, turn off the thermostatic
valve or set the operating mode selector to
Frost.
•
Make effective use of the temperature levels
and switching times for the domestic hot
water by setting them to suit the preferences
of the occupants.
– For manual valves via preselection.
– With fully opened thermostatic valves via
the return fitting.
If the thermostatic valves in the lead room
are not fully open, they may reduce the
heat supply even though the controller
requests heat.
•
Regulate the temperature in adjacent rooms
via thermostatic valves.
•
External heat in the lead room (e.g. solar
radiation, stove etc.) can result in too little
heating in adjacent rooms (the heating system
remains cold).
•
If heat-up optimisation is switched on:
•
To make best use of heat-up optimisation, set
the times for heating up to the temperature
levels for Economy or Comfort as late as
possible.
•
The heat-up optimisation function learns the
conditions in the lead room Æ chapter 8.3 on
page 46.
The first time heat-up optimisation is used,
there may be significant temperature
differences. During the initial learning phase,
do not change the setting before heat-up is
complete. After a few days, the learning
process will have advanced and the control
accuracy will improve.
•
Set the temperature for Economy or Frost as
low as possible.
•
During Economy or Frost the lead room
conditions must remain constantly the same
Æ chapter 8.3 on page 46.
If the conditions change, it can take several
days for heat-up optimisation to adapt to the
new conditions.
•
If the home is not heated for an extended
period, e.g. over the weekend, the rooms may

Much energy can be saved by reducing the
room temperature via economy phases.
Reducing the room temperature by 1 K ( °C)
enables up to 5% energy to be saved.
It is not recommended to let the room
temperature of heated rooms fall below
+15 °C during the daytime, otherwise the
cooled-down walls continue to radiate cold
and the room temperature rises higher,
leading to higher energy consumption than if
an even heat supply is applied.
Good thermal insulation of the building: the
set temperature for Economy is never
reached. Nevertheless energy is being saved

cool down to such an extent that the heating
appliance cannot bring them up to the
required temperature by the specified time
(start time for heating appliance up to 6 hours
before the set time for Economy or Comfort).
In that case, bring the time forward by an
appropriate amount.
•
Only charge the DHW cylinder outside the
heat-up period, e.g. 30 minutes after the
heating start time.
•
If the radiators become unpleasantly hot, the
maximum flow temperature should be
reduced accordingly on the heating appliance.
Solar optimisation
Activate the Optimizing influence DHW by
setting a figure of between 1 K and 20 K
Æ chapter 6.5 on page 38. If the influence of the
Optimizing influence DHW is too great, reduce
the setting step by step.
