2 Technical data for the accessory
item
•The FR 10 enables the room temperature control of a single
heating circuit.
•According to paragraph 12 of the EnEV (Order governing the
energy-saving thermal insulation and energy-saving system
technology in buildings in Germany), the FR 10 must only be
used in conjunction with a suitable time switch.
•In systems with a single heating circuit, you can change
automatically between the currently selected operating mode
/ / or heating operation blocked using the time
program of a time switch.
•The FR 10 can be used in systems with room temperature
controller FR 100/FR 110 to extend the system to up to 10
heating circuits (not permissible in Germany). For further
information, see the documentation of FR 100/FR 110.
•The controller is prepared for wall mounting.

3 Installation (for contractors
only)
3.1 Installation
The quality of control of the FR 10 is influenced by the installation
location.
The installation location (= lead room) must be suitable for
controlling the heating system or heating circuit.
BSelect installation location (ÆFig. 3 on page 161).
BRemove top section from base. (ÆFig. 4 on page 161).
BFit the base (ÆFig. 5 on page 161).
BMake electrical connections (ÆFig. 6 on page 162).
BPush on top section.
DANGER: Risk of electric shock!
BBefore installing this accessory:
Disconnect the power supply (220 to 240 V AC)
to the heating appliance and all other BUS
subscribers.
The mounting surface on the wall should be level.

3.2 Disposal
BDispose of packaging in an environmentally responsible
manner.
BWhen replacing components, dispose of the old components in
an environmentally responsible manner.
3.3 Electrical connections
BBUS connection from controller to other BUS subscribers:
Use cables that comply with local regulations and guidelines.
Permissible cable lengths from the BUS-enabled Heatronic 3 to
the controller:
BRoute all LV 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).

6 720 645 356 (2010/09)
5 Operation
The FR 10 can only regulate the heating system if an operating
mode is enabled. In conjunction with a time switch (accessory),
the time program automatically changes between the currently
selected operating mode / / and heating operation
blocked . Frost protection is ensured (ÆChapter 5.6 page 154).
Controls (ÆFig. 1 on page 159)
1Rotary selector :
- Turn = Adjust value
- Press = Confirm setting/value
2Modekey:
- Change operating mode
- Accessing user level = hold down for approx 3 seconds
- Accessing contractor level = Hold down for approx 6
seconds
- Return to the higher level

5.1 Changing the operating mode
BBriefly press mode until the required operating mode is
displayed.
= constant High
= constant Low
= constant Frost
The set operating mode is only active if heating operation is not
blocked .
5.2 Changing the required room temperature
BWith rotary selector adjust the required room
temperature for the current operating mode / / .
During this period, the required room temperature will flash
instead of the display showing the current room temperature.
The change to the required room temperature will remain in
force until the next operating mode change or until the power
is interrupted. At that point the system reverts to the room
temperature programmed at the user level for that particular
operating mode.
Use this function if you want to change the required
room temperature by way of an exception, e.g. for
the duration of a party.

124 | Operation
6 720 645 356 (2010/09)
5.3 Changing the standard setting of the required
room temperature
BAccessing user level: Hold down mode for approx. 3 seconds
until – – is displayed.
BRelease the mode key and turn until the required
parameter is shown:
–1A p = Required room temperature for High
–1b p = Required room temperature for Low
–1C p = Required room temperature for Frost
BBriefly press : The current temperature for the previously
selected parameter will be displayed.
BBriefly press : The current temperature flashes.
BTurn to adjust the required room temperature:
–High = maximum temperature required (e.g. if people are
spending time in the living areas and require a comfortable
temperature). Setting range is higher than Low up to
30 °C.
–Low = average temperature required (e.g. if a lower room
temperature is sufficient or if everyone is out or asleep and
the building must not cool down too much). Setting range
is higher than Frost and lower than High.
Use this function if you want to permanently change
the required room temperature away from the
standard setting.

Operation | 125
6 720 645 356 (2010/09)

5.4 Adjusting the contractor level (contractors
only)
BAccessing contractor level: Hold down mode for approx. 6
seconds until – – – is displayed.
BRelease the mode key and turn until the required
parameter is shown:
–5A p = Code
–5b p = Heating circuit configuration
–6A p = Calibrate the integral room temperature sensor

5.4.3 Calibrating the room temperature sensor (parameter: 6A p)
Setting range: – 3.0 °C (K) to +3.0 °C (K)
Use this parameter if you want to correct the displayed room
temperature.
BPosition a precision instrument near FR 10. The precision
instrument must not transfer any heat to the FR 10.
BKeep away heat sources such as sunlight, body heat, etc. for 1
hour.
BCalibrate the displayed room temperature correction value.
5.4.4 Selecting calibration factor I (parameter: 6b p)
Setting range: 0 % to 100 %
Calibration factor I represents the speed with which the constant
control deviation of the room temperature is compensated.
BSelecting calibration factor I:
–≤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.
