Operation
3.6 Special system settings
Adaption is carried out via the setting of parameters in the rotary
switch setting
"Configuration"
.
Navigating with the rotary switch accesses either the next deeper
level or directly to the appropriate parameter.
3.6.1 Access Rights (Technician password)
Certain settings are restricted by Controller access rights. In
order to gain access to these setting values (parameters) you
need to enter the expert
"Setup"
code in the level.
The fig. 3-12 shows the fundamental procedure for entering the
access code. The expert code will be advised to the expert
company in a separate letter.
3.6.2 Heat curve
With the heating characteristic curve, the inflow target temper-
ature is adjusted to building conditions in accordance with the rel-
evant external temperature (weather-controlled flow temperature
regulation, see section 3.6.4). Generally speaking, the steepness
of the heating characteristics describes the ratio of the flow tem-
perature change to the external temperature change.
The heating characteristic curve applies within the minimum and
maximum temperature limits that have been set for the corre-
sponding heating circuit. The room temperature measured in the
living area may differ from the desired room temperature; these
deviations can be kept to a minimum by installing a room station
or a room thermostat.
The
Controller
is
configured in the factory
so that the
heating
curve
does not adjust itself
during operation.
The
automatic heat curve adjustment
can only be activated by
the heating technician.
Starting conditions for the automatic heating curve adaption:
– Outdoor temperature < 8 °C
– Operating mode is automatic (I or II)
– Duration of setback phase at least 6 hours
If
an automatic heat curve adaption
is not activated, the heat
curve can be set
manually
by
adjusting
the
parameter [Heat-
Slope]
.

Manually adjusting the heating curve
Do not make any corrections to the set values for
1 - 2 days, and then only make them in small incre-
ments.
●
Deactivate additional heat sources (e.g. fireplaces,
direct solar radiation, open windows).
●
Fully open any existing radiator thermostat valves
or setting drives.
●
Activate the operating mode "Heating".
Approximate setting values:
– Radiator: 1.4 to 1.6.
– Under floor heating system: 0.5 to 0.9.
