Room influence These settings determine how the room temperature should influence flow tempera-
ture control. They are only applicable when a room sensor is connected in the heat
circuit.
Display text Parameter Default value,
range Description
Max. ampli-
fic. Maximum
amplification Default value:
0.0 K
Range:
– 25.0 - 25.0
K
If the room temperature exceeds the
room temperature setpoint, the flow tem-
perature in the heat circuit will be re-
duced according to the Max. amplific.
setting
Min. amplific. Minimum am-
plification Default value:
0.0 K
Range:
– 25.0 - 25.0
K
If the room temperature falls below the
room temperature setpoint, the flow tem-
perature in the heat circuit will be in-
creased according to the Min. amplific.
setting
Adaptive Default value:
OFF
Range:
ON, OFF
When the setting is ON, the flow tem-
perature is adjusted according to varia-
tions of the room temperature over a
period of time
!
Note:
When this setting is ON, the Max. am-
plific. and Min. amplific. settings should
be symmetrical with respect to 0, for
example, Max. amplific. = –3 K and
Min. amplific. = + 3 K
10.2.4 Limiter
This section describes the parameters you can set in pictures under the Limiter menu
item.
Return temperature The following settings affect the return temperature limiter. See also page 47.
Display text Parameter Default value,
range Description
Type Type of limi-
tation Default value:
MAX
Range:
MIN, MAX
Type of return temperature limitation
used: maximum or minimum. The flow
temperature is modified, when the return
temperature is either above the calcu-
lated setpoint or below it
Calc. setpoint Calculated
setpoint – The setpoint for the return temperature,
calculated from the return temperature
curve. This parameter is read-only and
cannot be set
