Excess temperature
Setting an increase in the heat requirement for the heat generator, in order to equalise
temperature losses caused by long pipes or leaking mixers.
Room temp. mod.
 Temperature modulation: Integration of the current room temperature for adjusting
the effective target room temperature using the following formula:
T
corr
= T
target
+ (T
target
– T
current
)
T
corr
= adjusted target room temperature (0..30 °C)
T
target
= desired target room temperature
T
current
= measured room temperature
(T
target
– T
current
) – max. 7 K
Example: T
target
= 21 °C (1), T
current
= 19 °C (2)
T
corr
= 21 °C + (21 °C – 19 °C)
T
corr
= 23 °C (3)
Result: The heating curve is translated by a
room temperature of 2 K. This results in an
increase in the flow temperature. This normally
also increases the room temperature.
Adjusting the heating curve using room temperature modulation
 Thermostat function: In addition to the "Temperature modulation" function, the fol-
lowing logic applies here: Switching off the heating when the room set target value
+
3
/
16
K has been reached. Switching it back on when the room set target value -
2
/
16
K has been reached.
 None: The target room temperature is used as set.
