Note:
CO is shown in the display of the ambient temperature controller with active
compensation.
To improve comfort and to maintain a reasonable temperature differential
when entering a room with a large window area, you should increase
the room temperature depending on the outside temperature in winter
(winter compensation). The ambient temperature is increased by adjusting
"heating setpoint comfort mode".
Similarly to summer compensation, an external temperature sensor that
sends its measured values to the KNX and therefore can be evaluated by
the ambient temperature controller with display is required to enable winter
compensation.
The following parameters are available for winter compensation
- "winter compensation lower temperature",
- "winter compensation upper outside temperature",
- "winter compensation lower setpoint offset" and
- "winter compensation upper setpoint offset".
The lower and upper outside temperature value specifies from and up
to which temperature a setpoint should be corrected.
The lower and upper setpoint offset specifies how many K the setpoint
should be adjusted during winter compensation in the parameters or by
the user.
Typical values for winter compensation are
- 0 °C: lower outside temperature
- 10 °C: upper outside temperature
- 4 K: lower setpoint offset
- 0 K: upper setpoint offset
This means that a floating setpoint increase from 0 to 4 K will be
implemented if the outside temperature falls from 10 °C to 0 °C.
