Starting up
Starting up
After the device has been properly installed (please
observe 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.

Set values Explanatory information

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 8K. The
heating circuit pump is switched on again when the
temperature of the heat generator drops below the
temperature [maximum flow temperature + 5K].
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
temperature by 1K.
=> High values lead to fast control and large heat
generator 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

Explanatory information Set values

Flow temperature [°C]
Outside temperature [°C]
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
temperature is stabilised in the storage tank for 24h
HW thermostat instead of HW sensor: Hot water
preparation 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
entered in Kelvin.
!Small values cause the mixer motor to adjust quickly
and can lead to oscillation.

Settings via DIP switch (rear side)
Switch 1-5 only valid in the case of HS controller without
operating module
HS minimum delimiter ( switch 1+2)
Reduces condensation build-up in boiler when heating
requirement is low. In all cases, the heat generator is
never switched off before the minimum boiler temperature
has been reached + +5K.
OFF, OFF = No HS minimum delimiter
OFF, ON = Minimum delimiter on heat slope
HS switches on when the temperature drops below the
temperature demanded by the consumers (flow set
temperature).
ON, OFF = Minimum delimiter during heat requirement
During heating requirement (pump enabled), the boiler
maintains at least the set minimum temperature
(40°C or 60°C).
ON, ON = Permanent minimum delimiter (24) The HS
maintains at least the set minimum temperature for
24h.
Minimum HS temperature (40°C <-> 60°C)
Reduces condensation build-up in boiler when heating
requirement is low. In all cases, the heat generator is
never switched off before the minimum boiler temperature
has been reached + +5K.
Parallel pump operation (F+D)
OFF => HW partial priority: The heating circuits are
blocked during hot water preparation. The mixers close
and the heating circuit pumps switch off. The mixer circuits
are enabled again when the heat generator has reached
the temperature of [hot water set temperature + heat
generator superheating]. If the heat generator temperature
drops below the enable temperature by the switching
hysteresis , the mixer circuits are blocked again.
ON => Parallel pump operation: During hot water heating
all heating circles are continued to heat. The hot water
heating is extended by this function.
Antibacteria function (F-> 65°C)
Every 20th heat-up operation, or once per week, the
storage tank is heated to 65°C.
Without operating module: In the case of fist charging after
one week has elapsed (Time indefinitely)
With operating module: On Saturday at 01:00 hrs
Sensor selection (5K NTC <-> 1K PTC)
Check the installed sensors (imprint, type plate, or
measurement value - see table) and set the switch
accordingly.
