Table 53 Room temperature, normal
▶ Set the measured value in the room.
The indicated value is used by temperature programs to calculate the
difference between normal and exceptional temperature.
>>> Temperature increase/decrease
Factory setting
Alternative
Table 54 Room temperature increase/decrease
▶ Use this function to adjust the room temperature so that the normal
room temperature (see the previous menu) becomes the desired
temperature.
▶ Use this function to simply increase or decrease the heat when there
are no room controllers.
– – gives approx. 1 °C lower room temperature.
– gives approx. 0.5 °C lower room temperature.
+ gives approx. 0.5 °C higher room temperature.
++ gives approx. 1 °C higher room temperature.

Table 55 Heating increase/decrease limit value
▶ Set which outdoor temperature should be the limit value for the end
point that should be adjusted when increase/decrease is requested.
At outdoor temperatures lower than the limit value, the flow
temperature in the right end point (-35 °C) of the heat curve is
affected, with change indicated in %, see below.
At outdoor temperatures higher than the limit value, the flow

Temperature increase/decrease.
>>> Room temperature influence
Set in the same way as in menu Room sensor (room controller)
( Chapter 20.1). The setting is used in the temperature program to
calculate how the flow line temperature is affected when Room
temperature exception is to apply.
>>> Room temperature during time program

The same as when there is a room controller, see above.
It always takes some time for a change of a heating
setting, e.g. an increase or decrease in room
temperature, to apply. The same applies in the event of a
quick change of the outdoor temperature. This is why
you should always wait for at least 24 hours before
making a new change.
> Circuit 2, 3...
Make the settings for the first mixed circuit under Circuit 2. Other
circuits are displayed only if they exist. The same functions apply to
these as the functions for circuit 2.

The factory settings for the Radiator have a curve value (flow
temperature) of 22 °C at 20 °C an outdoor temperature, 37.4 °C at –
2.5 °C and 60 °C at -35 °C at an outdoor temperature (the high point of
the curve).
The factory settings for the Underfloor have a curve value (flow
temperature) of 22 °C at 20 °C outdoor temperature, 27.2 °C at -2.5°C
and 35 °C at -35 °C outdoor temperature.
