ator or the heating circuit. When the incremental encoder
is rotated, the following temperatures are displayed: 1.
Outside temperature (S, arrow 1),
2. Hot water temperature (F, arrow 2) => key: Set value
3. Room temperature(R, arrow 4) => key: Set value
Display „- -„ => No measured value available.

Starting up
Starting up
After the device has been properly installed (please ob-
serve the switch position on the rear side of your device),
switch on the power supply.
The software number for your device and then the index of
your software briefly appears in the display.
Then the readout appears in accordance with the position
of the rotating switch.
The controller is now operational => "Run"
Modifying set values
Rotate the selection switch to the corresponding set value
The display shows the currently set value.
Press the OK key.
The value starts to flash and can now be changed using
the rotary knob.
By pressing the button key OK once more, the value is
stored in the device.
Rotate the rotating switch to RUN Automatic mode
=> the mode is activated after 2 seconds.

Explanatory information
Set values
Room set temperature
Only effective if an outside sensor or a room sensor
(without operating module) is connected.
=> Setting the desired room temperature
Flow set temperature (fixed value)
Only takes effect if no outdoor sensor, room sensor, or
operating module is connected.
=> Input of the desired flow / return flow temperature.
Maximum flow temperature
If an outdoor sensor or a room sensor is connected
The measured temperature setting for the heating circuit
flow is limited to the maximum flow temperature setting
(overheating protection).
EThe heating circuit pump of the direct heating circuit is
switched off if the temperature of the heat generator
exceeds the maximum flow temperature by 8 K. The
heating circuit pump is switched on again when the
temperature of the heat generator drops below the
temperature [maximum flow temperature + 5 K].
Room sensor
Only active if a room sensor or the FBR analogue room
device (room sensor + selection of operating mode) is
connected..
The flow set temperature is increased by the set value
when the temperature drops below the required room tem-
perature by 1 K.
=> High values lead to fast control and large heat genera-
tor temperature fluctuations.
- - - - => pure weather-dependent control
0 => pure weather-dependent control *)
20 => pure room temperature control
*) Special function with ROOMS-INFL = 0
For one-off heating requirements during the night reduction
the heating pump continues to run until the next heating
period is reached (see chapter entitled "Circulation pump
control").
Heat-Slope
Only active if an outside sensor (without operating module)
is connected.. The gradient of the heat slope indicates by
how many degrees the flow temperature changes if the
outside temperature rises or drops by 1 °C.
Setting tip:
At cold outside temperatures, room temperature too low =>
Increase heat slope (and vice-versa)
At high outside temperature (e.g.16 °C) room temperature
too low => correction via set room temperature

Heat slope diagram (setting aid)
Setting 0 => Room control only
!The heat slope can best be set at outside
temperatures below 5 °C. The change in heat slope
setting must be made in small steps and at long
intervals (min. 5 to 6 hours) because the system
must first adjust to the new values each time the
heat slope is changed.
Guideline values
Underfloor heating S = 0.4 to 0.6
Radiator heating S = 1.0 to 1.5
Hot water set temp. (only in the case of boiler module)
Setting the desired hot water temperature. This tempera-
ture is stabilised in the storage tank for 24 h
HW thermostat instead of HW sensor: Hot water prepara-
tion in the event of short circuit on the sensor input.
If a corresponding operating device is connected the hot
water function is only activated during hot water enable
times.
Mixer dynamic (only in the case of mixer module)
Speed setting at which the mixer motor adjusts when a
control difference occurs. The control difference at which
the mixer motor opens/closes without interruption is en-
tered in Kelvin.
!Small values cause the mixer motor to adjust quickly
and can lead to oscillation.
BUS-ID (heating circuit number)
KM: [- -] HS with direct heating circuit and Hot water
[00] HS with header pump and Hot water
[01 - 08] [11-88] HS in a cascade with HS-Pump
=> Enter number of the heat generator. Setting > 08 can
be supported only during cascading by cascades with ap-
propriate cascade managers.
MM: The heating circuits are sequentially numbered start-
ing with "01". heating circuit numbers must not be assigned
twice. For replacement controllers, please enter exactly the
same heating circuit numbers as the replaced controller.
