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
Adaption (Heating curve adaption)
Only active if an FBR analogue room device is connected
(room operating mode selection) and an outdoor
sensor.
Function for automatic heal slope setting
Starting Conditions:
External temperature < 8°C
Operating mode is automatic (I or II)
Duration of lowering phase at least 6 hours
At the beginning of the lowering period, the current room
temperature is measured. During the next four hours, this
temperature is used as the set point for the room
regulator. The heating curve is calculated from the values
determined during this time by the regulator for the flow
pipe nominal temperature and the external temperature.
!
The parameter remains activated until the
adjustment has been completed successfully
without an interruption due, for example, to a Warm
Up Temp or the hot water requirement of an
external circuit.
!
During the adaptation, the water heating and the
heating optimisation of the regulator are blocked.
Room Influence (Room sensor influence)
Only active if an FBR analogue room device is connected
(room operating mode selection).
The HS 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 HS
temperature fluctuations.
OFF- => pure weather-dependent control
0
=> pure weather-dependent control **)
20
=> pure room temperature control
**) Special function with room influence = 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").
T-Room adj (Room sensor adaptation)
In the case of room control (e.g. with FBR) the
measurement can be corrected using this setting if the
room sensor is not measuring correctly.
Heat up opti (heatup optimisation)
Activation of function for automatically bringing forward
the start of heating.
Example: Heating program 6:00 hrs – 22:30 hrs
OFF:
Building starts to be heated at 6:00 hrs.
ON:
Depending on weather and room temperature,
heating starts soon enough so that building just reaches
the set room temperature at 6:00 hrs.
00 => start of heating not brought forward
01 => brought forward depending on weather
02 => brought forward depending on room temperature *)
*) Only active if an FBR analogue room device is
connected (room operating mode selection).
!
Heatup optimisation occurs only if the reduced time
of the heating circuit is at least 6 hours.
Max Opt-Time (Maximum bring-forward)
Only active with "Optim Heat = T-Outside or T-Room"
The start of heating is brought forward by no more than
this time.
Opt reduced (Reduction optimisation)
Automatic reduction of burner disabling to end of set
heating time.
The burner is not restarted before the end of the heating
period during the set time period (last heating time only) if
it not already in operation.
This function prevents short-term heating of the heat
generator to the end of the heating period.
PC enable
Code number for enabling access to heating circuit data
from a PC
"0000" => access PC and terminal is blocked.
"0001“ => access is free of Terminal / access PC is
blocked.
