5.8.1 Flash adaptation without outdoor sensor (room temperature
dependent)
The flow temperature control starts with
Flow day set point in rated operation or with Flow
night set point in reduced operation as no set points calculated using characteristics exist
without an outdoor sensor. In rated operation, the heating is switched off when the room
temperature exceeds the
Day set point by 2 °C. In reduced operation, the heating is switched
off when the room temperature exceeds the
Night set point by 2 °C. If the Cycle time is set to
1 minute, the current correction value is not lost on changing from rated to reduced opera-
tion or vice versa. Instead, it is integrated into the calculation of the
Flow day set point or
Flow night set point.

Adaptation
The controller is capable of automatically adapting the heating characteristic to the building
characteristics, provided a gradient characteristic has been set (CO1, 2 -> F11 - 0). The ref-
erence room, where the room sensor is located, represents the entire building and is moni-
tored to ensure that the room set point (
Day set point) is maintained. When the mean mea-
sured room temperature in rated operation deviates from the adjusted set point, the heating
