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

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.
OFF: The saving temperature does not depend on the
outdoor temperature.
-29 ... 10: 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. When
the outdoor temperature is below the set limit, there is
no temperature reduction.
The comfort and the saving temperatures are set in the display
overviews. The difference between the comfort and the saving
temperature is considered to be 100%. Depending on the outdoor
temperature, the percentage value can be lower according to the
set value in 'Auto saving' .

Boost
Circuit
1
Shortens the heating-up period by increasing the desired flow temperature
by the percentage you set.
OFF:
The boost function is not active.
1-99%: The desired flow temperature is increased temporarily
with the set percentage.
In order to shorten the heating-up period after a saving
temperature period, the desired flow temperature can be increased
temporarily (max. 1 hour). At optimizing the boost is active in the
optimization period ('Optimizer').
If a room temperature sensor or an ECA 30 / 31 is connected, the
boost stops when the room temperature is reached.

Setting in 'Auto saving':
The drawing above illustrates that the reduction percentage at an
outdoor temperature of –5 °C is 40%.
The difference between Comfort and Saving temperature is (22–16)
= 6 degrees.
40% of 6 degrees = 2.4 degrees
The 'Auto saving' temperature is corrected to (22–2.4) = 19.6 °C.
