Summer mode only becomes effective when the controller is in automatic mode ( ).
5.6 Delayed outdoor temperature adaptation
The calculated outdoor temperature is used to determine the flow temperature set point. The
heat response is delayed when the outdoor temperature either decreases, or increases and de
-
creases. If the outdoor temperature varies by, for example, 12 °C within a very short period of
time, the calculated outdoor temperature is adapted to the actual outdoor temperature in small
steps. Assuming a
Delay
of 3 °C/h, the adaptation would take

Note!
The delayed outdoor temperature adaptation helps avoid unnecessary overloads of central
heating stations in combination with either overheated buildings occurring, for example, due to
warm winds, or temporarily insufficient heating due to the outdoor sensor being exposed to di-
rect sunshine.
In the operating level, the outdoor temperature blinks on the display while delayed outdoor tem-
perature adaptation is active. The calculated outdoor temperature is displayed.

5.7 Outdoor temperature-dependent advance heating
The controller activates the heating depending on the outdoor temperature before the
time-of-use starts in normal operation. The
Advance heating time
is based on an outdoor tem
-
perature of –12 °C. The advance heating time is shorter when the outdoor temperature is
higher.
