Auto saving (saving temp. dependent on outdoor temp.)

1x011

Below the set value for the outdoor temperature, the saving temperature
setting has no influence. Above the set value for the outdoor temperature,
the saving temperature relates to the actual outdoor temperature. The
function is relevant in district heating installations in order to avoid a big
change in the desired flow temperature after a saving period.

See Appendix “Parameter ID overview”

OFF:

The saving temperature does not depend on the
outdoor temperature; the reduction is 100%.

Value:

The saving temperature depends on the outdoor
temperature. When the outdoor temperature is above
10 °C, the reduction is 100%. The lower the outdoor
temperature, the less the temperature reduction.
Below the set value, the saving temperature setting
has no influence.

Comfort temperature:

The desired room temperature in
Comfort mode

Saving temperature:

The desired room temperature in Saving

The desired room temperatures for Comfort and Saving modes
are set in the display overviews.
